00:06:31.609 --> 00:06:34.237 00:06:34.237 --> 00:06:37.085 What scientists discovered is that as humans 00:06:37.085 --> 00:06:39.712 evolved, another part of the brain called 00:06:39.712 --> 00:06:43.950 the Cortex, also become involved in processing fear. 00:06:43.950 --> 00:06:45.595 >> The part that makes us most human 00:06:45.595 --> 00:06:48.495 about the brain is our frontal cortex. 00:06:48.495 --> 00:06:50.599 >> If the amygdala is the first floor, 00:06:50.599 --> 00:06:53.547 the cortex is the second floor of the brain. 00:06:54.702 --> 00:06:57.813 It's the brain's thin, wrinkly outer layer that's 00:06:57.813 --> 00:07:00.077 divided into four sets of lobes. 00:07:00.323 --> 00:07:01.980 >> If you unfolded the cortex of a monkey, 00:07:01.980 --> 00:07:03.855 it would be about the size of the piece of paper. 00:07:03.855 --> 00:07:06.619 If you unfolded our cortex, it is about four sheets 00:07:06.619 --> 00:07:09.678 of paper - large - and the reason it is wrinkly is 00:07:09.678 --> 00:07:11.453 because you have to squish that all inside 00:07:11.453 --> 00:07:12.729 of the skull. 00:07:12.729 --> 00:07:15.408 >> The Frontal Lobes comprise the area just above 00:07:15.408 --> 00:07:17.989 our eyes and these are the newest rooms 00:07:17.989 --> 00:07:19.025 of the brain. 00:07:19.025 --> 00:07:19.704 00:07:19.704 --> 00:07:22.386 As humans evolved, the frontal lobes became the 00:07:22.386 --> 00:07:24.324 place where conscious rational thought 00:07:24.324 --> 00:07:25.696 is processed. 00:07:25.864 --> 00:07:28.292 It's where we do our problem solving. 00:07:28.292 --> 00:07:30.414 >> The frontal lobes are so interesting 00:07:30.414 --> 00:07:34.872 because they're really the conductor of the brain. 00:07:34.872 --> 00:07:38.545 They synchronize all activity. 00:07:38.652 --> 00:07:40.780 >> Scientists made a major breakthrough 00:07:40.780 --> 00:07:43.382 in fear research when they found that information 00:07:43.382 --> 00:07:46.162 from our senses reaches the amygdala almost 00:07:46.162 --> 00:07:49.321 twice as fast as it takes to get to our frontal lobes. 00:07:49.321 --> 00:07:50.290 00:07:50.290 --> 00:07:53.152 The speed of the different brain signals means 00:07:53.152 --> 00:07:55.547 unless we instinctively know how to react 00:07:55.547 --> 00:07:58.486 to a potential threat, we may freeze in fear 00:07:58.486 --> 00:08:00.968 waiting for the frontal lobes to catch up 00:08:00.968 --> 00:08:03.181 to figure out the right response. 00:08:03.181 --> 00:08:05.455 >> Part of what happens with fear and panic is 00:08:05.455 --> 00:08:07.529 the unknown, is the not knowing what to do next 00:08:07.529 --> 00:08:09.011 and so your brain essentially freezes 00:08:09.011 --> 00:08:11.206 the way a deer freezes in a headlight. NOTE Paragraph 00:08:11.206 --> 00:08:13.240 >> So, the amygdala may get very fast signals 00:08:13.240 --> 00:08:15.999 about fear but sometimes they're wrong 00:08:15.999 --> 00:08:18.331 and quickly the situation may say to you, 00:08:18.331 --> 00:08:20.782 no it's not a fear situation and you're not afraid. 00:08:20.782 --> 00:08:23.176 So, these very quick amygdala signals that you get 00:08:23.176 --> 00:08:26.603 can be controlled in sort of a top down way. 00:08:26.603 --> 00:08:29.209 >> This is where the Navy's training comes in. 00:08:29.209 --> 00:08:32.003 It teaches recruits to minimize that delay by 00:08:32.003 --> 00:08:35.249 generating fast, accurate reactions to situations. 00:08:35.249 --> 00:08:47.627 00:08:47.627 --> 00:08:50.281 With demand for special forces increasing, 00:08:50.281 --> 00:08:51.974 the Navy continues to develop 00:08:51.974 --> 00:08:54.978 brain training techniques to see if they can 00:08:54.978 --> 00:08:57.709 improve the pass rate. 00:08:57.709 --> 00:08:59.953 But there are some fears that scientists 00:08:59.953 --> 00:09:02.816 believe are pre-programmed into our brains, 00:09:02.816 --> 00:09:06.140 primal fears or super fears that few 00:09:06.140 --> 00:09:08.287 people can overcome. 00:09:08.287 --> 00:09:10.353 The Navy makes its trainees tackle these 00:09:10.353 --> 00:09:11.574 head on. 00:09:11.574 --> 00:09:14.192 It's why their most dreaded exercise happens 00:09:14.192 --> 00:09:15.459 under water. 00:09:15.459 --> 00:09:16.177 00:09:16.177 --> 00:09:18.816 As recruits face the fear of drowning.

learning more now about the brain 00:09:32.396 --> 00:09:34.703 than at any other time in history. 00:09:34.703 --> 00:09:37.616 How it's put together and how it operates. 00:09:39.140 --> 00:09:41.070 Breakthroughs in brain science are helping 00:09:41.070 --> 00:09:44.325 the Navy to rethink how they train Seal recruits. 00:09:44.325 --> 00:09:48.561 00:09:48.561 --> 00:09:51.192 Specialized exercises can improve their brains' 00:09:51.192 --> 00:09:54.115 reactions in fearful combat situations. 00:09:54.115 --> 00:09:54.997 00:09:54.997 --> 00:09:57.192 But the candidates need something more to cope 00:09:57.192 --> 00:09:59.409 with a super fear like drowning. 00:09:59.409 --> 00:10:03.698 00:10:03.698 --> 00:10:06.470 Experts believe evolution has hard-wired 00:10:06.470 --> 00:10:10.049 our brains to dread being trapped under water. 00:10:10.049 --> 00:10:13.144 As a result, it's almost impossible to control 00:10:13.144 --> 00:10:16.273 the brain's overwhelming impulse to surface for air. 00:10:16.273 --> 00:10:19.098 00:10:19.098 --> 00:10:21.811 And it is why recruits struggle so much to pass 00:10:21.811 --> 00:10:24.134 the Underwater Pool Competency Test. 00:10:24.134 --> 00:10:30.416 00:10:30.416 --> 00:10:32.841 >> Pool Comp is a very important milestone 00:10:32.841 --> 00:10:34.185 in their career here. 00:10:34.185 --> 00:10:36.795 They're being tested how they can deal with 00:10:36.795 --> 00:10:38.011 fear under water. 00:10:38.011 --> 00:10:40.026 And there is controlled harassment, 00:10:40.026 --> 00:10:42.238 planned harassment projected at them 00:10:42.238 --> 00:10:44.981 under water and we see how they can cope with that. 00:10:44.981 --> 00:10:47.961 >> Students must spend up to 20 minutes under water 00:10:47.961 --> 00:10:50.149 enduring repeated attacks on their breathing 00:10:50.149 --> 00:10:52.334 equipment by an instructor. 00:10:52.334 --> 00:10:55.357 Half of the time they are without air. 00:10:55.357 --> 00:10:57.075 >> Their air is shut off, 00:10:57.075 --> 00:11:00.107 their breathing hoses are wrapped around in 00:11:00.107 --> 00:11:03.488 difficult positions and they need to respond 00:11:03.488 --> 00:11:05.829 to those problems with a series 00:11:05.829 --> 00:11:08.054 of emergency procedures. 00:11:09.116 --> 00:11:12.002 >> Step by step instructions for untangling their gear 00:11:12.002 --> 00:11:14.503 are drilled into the recruits' heads beforehand. 00:11:15.410 --> 00:11:17.709 They must follow these to the letter. 00:11:17.709 --> 00:11:18.466 00:11:18.466 --> 00:11:21.356 But putting theory into practice isn't easy. 00:11:21.356 --> 00:11:24.944 00:11:24.944 --> 00:11:26.673 >> You go down to the bottom and the instructors 00:11:26.673 --> 00:11:28.380 they come down and will start attacking you, 00:11:28.380 --> 00:11:29.661 taking your mask off, 00:11:29.661 --> 00:11:30.990 just creating all this stress 00:11:30.990 --> 00:11:32.836 and the more the stress builds up, 00:11:32.836 --> 00:11:34.019 they want to see how you'll handle it. 00:11:34.634 --> 00:11:36.865 >> As the trainee begins running out of air, 00:11:36.865 --> 00:11:39.332 his brain's amygdala pushes the panic button 00:11:39.332 --> 00:11:41.608 that urges him to surface. 00:11:41.608 --> 00:11:44.573 His frontal lobes must win this battle in the brain 00:11:44.573 --> 00:11:46.822 if he is to stay in control. 00:11:46.822 --> 00:11:48.430 >> Physically it is very challenging. 00:11:48.430 --> 00:11:50.191 You have to hold your breath for longer than 00:11:50.191 --> 00:11:51.384 you normally would. 00:11:51.384 --> 00:11:53.070 The instructors just take you kind of to that 00:11:53.070 --> 00:11:55.163 breaking point to see how you'll respond. 00:11:55.809 --> 00:11:58.426 >> No sooner has the candidate untied one set of 00:11:58.426 --> 00:12:01.042 knots then his instructor is back attacking 00:12:01.042 --> 00:12:02.936 him again and again. 00:12:02.936 --> 00:12:04.653 >> The more the stress builds up they want to see 00:12:04.653 --> 00:12:05.698 how you'll handle it. 00:12:05.698 --> 00:12:07.106 Will you want to go to the surface and get air, 00:12:07.106 --> 00:12:08.004 which you want to do, 00:12:08.004 --> 00:12:09.909 or will you take the little air you have 00:12:09.909 --> 00:12:11.810 and all the problems and solve them and do 00:12:11.810 --> 00:12:14.202 what's necessary to pass the test? 00:12:14.202 --> 00:12:16.110 >> More Seals fail Pool Comp 00:12:16.110 --> 00:12:18.983 at this stage in their training than anything else. 00:12:18.983 --> 00:12:20.925 The Navy wanted to know what was going on 00:12:20.925 --> 00:12:23.855 inside their recruits' heads to cause this. 00:12:24.870 --> 00:12:26.451 >> And there's almost nothing more scary 00:12:26.451 --> 00:12:28.099 than not being able to breathe. 00:12:28.099 --> 00:12:30.624 That creates a tremendous stress response. 00:12:30.624 --> 00:12:32.649 You have this huge release of stress hormones 00:12:32.649 --> 00:12:35.206 that make controlling things with thought 00:12:35.206 --> 00:12:36.529 more difficult. 00:12:36.529 --> 00:12:38.826 00:12:38.826 --> 00:12:41.233 >> Under normal conditions, the brain communicates 00:12:41.233 --> 00:12:44.829 with the body using minute electrical signals. 00:12:44.829 --> 00:12:47.444 The brain sends out electrical impulses 00:12:47.444 --> 00:12:49.898 from its nerve cells to others that travel at over 00:12:49.898 --> 00:12:52.087 270 miles per hour. 00:12:53.731 --> 00:12:56.312 This is one way your brain can tell your body 00:12:56.312 --> 00:12:57.680 to do something. 00:12:57.680 --> 00:12:59.252 00:12:59.252 --> 00:13:01.037 But under extreme duress, 00:13:01.037 --> 00:13:03.110 the brain releases chemical hormones. 00:13:03.957 --> 00:13:06.275 The part of the brain that senses fear, 00:13:06.275 --> 00:13:07.255 the amygdala, 00:13:07.255 --> 00:13:09.483 triggers a chain reaction that sends 00:13:09.483 --> 00:13:11.601 adrenaline and cortisol hormones 00:13:11.601 --> 00:13:13.764 into the body's blood stream. 00:13:13.764 --> 00:13:16.192 These stress hormones act as a SWAT team, 00:13:16.192 --> 00:13:19.074 quickly preparing the body for action. 00:13:19.074 --> 00:13:21.143 They increase breathing, heart rate, 00:13:21.143 --> 00:13:23.172 and blood pressure. 00:13:23.172 --> 00:13:25.136 Senses become keener, 00:13:25.136 --> 00:13:26.638 memory sharper, 00:13:26.638 --> 00:13:29.376 and the body becomes less sensitive to pain. 00:13:29.376 --> 00:13:29.996 00:13:29.996 --> 00:13:32.218 But even in this heightened state of alertness, 00:13:32.218 --> 00:13:35.585 Pool Comp is still too challenging for many trainees. 00:13:35.585 --> 00:13:37.778 00:13:37.778 --> 00:13:39.673 >> Your mind is going everywhere and you're seeing 00:13:39.673 --> 00:13:41.274 your friends swim up from up the water - 00:13:41.274 --> 00:13:42.757 they've passed or they've failed. 00:13:42.757 --> 00:13:44.455 And you're kind of sizing yourself up 00:13:44.455 --> 00:13:46.046 saying, well he failed can I pass? 00:13:46.046 --> 00:13:47.279 And vice versa. 00:13:47.279 --> 00:13:48.974 So, your mind goes everywhere and it is key 00:13:48.974 --> 00:13:51.140 just to stay focused on what you have to do. 00:13:52.064 --> 00:13:55.356 >> Eventually, the student completes the series of tasks 00:13:55.356 --> 00:13:57.593 and can touch the bottom and then surface 00:13:57.593 --> 00:13:58.993 to learn from the instructor 00:13:58.993 --> 00:14:00.729 whether he's passed the test. 00:14:00.729 --> 00:14:07.353 00:14:07.353 --> 00:14:08.870 >> I feel fine! 00:14:08.870 --> 00:14:11.193 >> Few Seal candidates succeed at Pool Comp 00:14:11.193 --> 00:14:12.439 the first time. 00:14:12.439 --> 00:14:14.181 They get four attempts and there's more 00:14:14.181 --> 00:14:15.798 at stake with each try. 00:14:17.322 --> 00:14:21.151 >> The most common reason for failing Pool Comp 00:14:21.151 --> 00:14:26.256 is panic, losing composure under water. 00:14:26.256 --> 00:14:28.496 Some of our students, that's it, 00:14:28.496 --> 00:14:32.260 we will performance drop them from training. 00:14:32.813 --> 00:14:34.690 >> The Navy wanted to help borderline 00:14:34.690 --> 00:14:36.976 candidates who had the potential to pass 00:14:36.976 --> 00:14:39.171 these crucial phases in training. 00:14:39.171 --> 00:14:41.604 00:14:41.604 --> 00:14:43.322 After consulting with experts, 00:14:43.322 --> 00:14:45.149 they came up with a ground-breaking 00:14:45.149 --> 00:14:47.007 mental toughness program. 00:14:47.007 --> 00:14:48.936 A set of techniques to boost the trainees' 00:14:48.936 --> 00:14:50.740 ability to control fear. 00:14:50.740 --> 00:14:52.338 00:14:52.338 --> 00:14:54.672 Even in the most extreme situations. 00:14:54.672 --> 00:14:56.367 00:14:56.367 --> 00:14:57.742 >> You guys need to stay fired up while 00:14:57.742 --> 00:14:58.754 you're out there. 00:14:58.754 --> 00:15:00.743 The pain, the cold, and all that stuff 00:15:00.743 --> 00:15:01.966 it's going to eat away at you 00:15:01.966 --> 00:15:03.529 but you got to keep going. 00:15:03.529 --> 00:15:05.279 >> The techniques that we're most interested in 00:15:05.279 --> 00:15:07.071 are what I call the Big Four: 00:15:07.071 --> 00:15:07.826 Goal Setting, 00:15:07.826 --> 00:15:08.791 Mental Rehearsal, 00:15:08.791 --> 00:15:09.823 Self Talk, 00:15:09.823 --> 00:15:11.071 and Arousal Control. 00:15:11.071 --> 00:15:13.852 00:15:13.852 --> 00:15:16.030 >> Scientists think goal setting works by 00:15:16.030 --> 00:15:17.970 assisting the frontal lobes. 00:15:17.970 --> 00:15:20.800 As the brain's supervisor, the frontal lobes 00:15:20.800 --> 00:15:23.148 are responsible for reasoning and planning. 00:15:23.148 --> 00:15:24.010 00:15:24.010 --> 00:15:25.826 Concentrating on specific goals, 00:15:25.826 --> 00:15:28.511 let's the brain bring structure to chaos 00:15:28.511 --> 00:15:31.167 and keeps the amygdala, the emotional center 00:15:31.167 --> 00:15:32.977 of the brain, in check. 00:15:32.977 --> 00:15:39.755 00:15:39.755 --> 00:15:41.245 >> I got up every morning and I said, 00:15:41.245 --> 00:15:43.121 I'm going to make it to breakfast. 00:15:43.121 --> 00:15:44.251 And then at breakfast I said, 00:15:44.251 --> 00:15:45.678 OK, I'm going to make it to lunch. 00:15:45.678 --> 00:15:47.957 And then I'm going to make it through 00:15:47.957 --> 00:15:49.188 the run this afternoon. 00:15:49.188 --> 00:15:53.564 And then you take it in these little sort of chunks. 00:15:55.240 --> 00:15:57.296 >> The second technique, Mental Rehearsal, 00:15:57.296 --> 00:15:58.630 or Visualization, 00:15:58.630 --> 00:16:00.589 is continually running through 00:16:00.589 --> 00:16:01.780 an activity in your mind. 00:16:01.780 --> 00:16:04.947 So when you try it for real, it comes more naturally. 00:16:04.947 --> 00:16:07.842 00:16:10.737 --> 00:16:13.633 >> If you practice in your mind first 00:16:13.633 --> 00:16:15.992 and imagine and rehearse how you might do 00:16:15.992 --> 00:16:17.431 in these stressful situations, 00:16:17.431 --> 00:16:19.098 the next time in reality you're faced with 00:16:19.098 --> 00:16:21.497 these situations is actually in effect, 00:16:21.497 --> 00:16:23.917 the second time you've faced it so you'll have 00:16:23.917 --> 00:16:25.534 less of a stressful reaction. 00:16:25.534 --> 00:16:26.782 00:16:26.782 --> 00:16:29.093 >> The third technique, Self Talk, 00:16:29.093 --> 00:16:30.973 helps focus the trainees' thoughts. 00:16:32.481 --> 00:16:35.013 The average person speaks to themselves at a 00:16:35.013 --> 00:16:38.122 rate of 300 to 1000 words a minute. 00:16:38.122 --> 00:16:40.944 00:16:40.944 --> 00:16:44.062 If these words are positive instead of negative, 00:16:44.062 --> 00:16:46.640 'can do' instead of 'can't', 00:16:46.640 --> 00:16:48.887 they help override the fear signal 00:16:48.887 --> 00:16:51.027 coming from the amygdala. 00:16:51.857 --> 00:16:55.193 >> The frontal lobes are always on so it is very easy 00:16:55.193 --> 00:16:57.519 to think about something difficult, something bad, 00:16:57.519 --> 00:17:00.654 like I'm going to fail, what am I doing here? 00:17:00.654 --> 00:17:03.024 I didn't practice enough. 00:17:03.024 --> 00:17:04.653 What you're trying to do is you're trying to replace 00:17:04.653 --> 00:17:07.348 those bad thoughts with good thoughts. 00:17:07.348 --> 00:17:09.435 00:17:11.927 --> 00:17:14.619 >> The final technique, Arousal Control, 00:17:14.619 --> 00:17:16.774 is centered on breathing. 00:17:16.774 --> 00:17:19.590 Deliberate slow breathing helps combat some of the 00:17:19.590 --> 00:17:21.181 effects of panic. 00:17:22.518 --> 00:17:25.598 Long exhales in particular, mimic the body's 00:17:25.598 --> 00:17:28.326 relaxation process and get more oxygen to the 00:17:28.326 --> 00:17:30.430 brain so it can perform better. 00:17:30.430 --> 00:17:32.300 00:17:32.300 --> 00:17:34.459 >> Breathing is a great focusing strategy 00:17:34.459 --> 00:17:37.123 but you can only do it so much because 00:17:37.123 --> 00:17:38.612 in a response to fear, 00:17:38.612 --> 00:17:40.906 your brain will get jacked up. 00:17:40.906 --> 00:17:43.963 00:17:43.963 --> 00:17:46.923 >> On it's own, arousal control wouldn't work. 00:17:46.923 --> 00:17:49.405 The amygdala sends out such a powerful signal 00:17:49.405 --> 00:17:53.211 it's tough to suppress if we're still feeling fearful 00:17:53.211 --> 00:17:55.618 but combing the four techniques 00:17:55.618 --> 00:17:57.509 made a big difference to the trainee Seals 00:17:57.509 --> 00:17:59.816 pass rate, increasing it from a quarter 00:17:59.816 --> 00:18:01.163 to a third. 00:18:01.163 --> 00:18:04.172 The idea of pushing boundaries may not be new 00:18:04.172 --> 00:18:07.169 but here is positive proof that you can train 00:18:07.169 --> 00:18:10.399 your brain and now science knows how. 00:18:10.399 --> 00:18:14.855 00:18:14.855 --> 00:18:17.321 >> It goes back to a lot of much earlier sort of 00:18:17.321 --> 00:18:20.192 warrior traditions where you're sort of transcending 00:18:20.192 --> 00:18:23.622 whatever it is you thought your limitations were. 00:18:23.622 --> 00:18:26.171 00:18:26.171 --> 00:18:27.849 >> I am a different person, actually. 00:18:27.849 --> 00:18:30.236 Your confidence goes through the roof. 00:18:30.236 --> 00:18:32.502 You see things and do things that you wouldn't 00:18:32.502 --> 00:18:34.480 have imagined before. 00:18:34.480 --> 00:18:37.042 >> But it's not just the battlefield where brain science 00:18:37.042 --> 00:18:38.993 is having a big impact. 00:18:38.993 --> 00:18:42.061 It's also unlocking some tantalizing secrets about 00:18:42.061 --> 00:18:44.910 what happens in the bedroom. 00:18:44.910 --> 00:18:47.399 >> Everybody knows sex is between the ears 00:18:47.399 --> 00:18:49.646 and we wanted to find out what is really going on. 00:18:49.646 --> 00:18:55.866 00:18:55.866 --> 00:18:58.458 >> While the brain has evolved a fear response 00:18:58.458 --> 00:19:00.467 to keep us out of danger, 00:19:00.467 --> 00:19:03.984 it is also equipped with a strong sexual impulse 00:19:03.984 --> 00:19:07.382 to ensure the survival of the species. 00:19:07.382 --> 00:19:09.735 >> Having an orgasm is one of the most powerful 00:19:09.735 --> 00:19:13.308 human experiences so begin to creep into the mind 00:19:13.308 --> 00:19:16.372 and find out exactly how the brain is producing 00:19:16.372 --> 00:19:19.618 this overwhelming ecstasy is exciting. 00:19:20.402 --> 00:19:22.426 >> In the Netherlands neuroscientist, 00:19:22.426 --> 00:19:23.954 Dr. Gert Holstege, 00:19:23.954 --> 00:19:27.807 is blazing a trail in sex research by revealing 00:19:27.807 --> 00:19:30.517 for the first time what happens in the brains 00:19:30.517 --> 00:19:32.688 of men and women during orgasm. 00:19:32.688 --> 00:19:33.556 00:19:33.556 --> 00:19:35.200 >> 15 years ago it was not possible 00:19:35.200 --> 00:19:37.799 but now with newer imaging techniques, 00:19:37.799 --> 00:19:40.791 it is very well possible to see what's happening. 00:19:40.791 --> 00:19:43.780 >> To find out, he needs volunteer couples. 00:19:43.780 --> 00:19:46.026 The man or woman agrees to be injected 00:19:46.026 --> 00:19:49.410 with a radioactive oxygen tracer and then stimulated 00:19:49.410 --> 00:19:51.046 to orgasm by their partner. 00:19:52.738 --> 00:19:54.946 While this happens, they lie with their head 00:19:54.946 --> 00:19:58.084 in a 3D imaging machine called a PET scanner. 00:19:58.084 --> 00:20:02.351 00:20:02.351 --> 00:20:05.229 >> The PET scanner is measured in only blood flow. 00:20:05.229 --> 00:20:08.229 It is measuring the amount blood going to different 00:20:08.229 --> 00:20:09.949 parts of the brain. 00:20:10.549 --> 00:20:13.782 >> The brain has many miles of blood vessels. 00:20:13.782 --> 00:20:16.133 When nerve cells are busy firing, 00:20:16.133 --> 00:20:18.305 they need lots of energy-laden 00:20:18.305 --> 00:20:20.425 and oxygen-rich blood. 00:20:20.425 --> 00:20:22.870 When they're not, they need very little. 00:20:22.870 --> 00:20:23.853 00:20:23.853 --> 00:20:28.103 >> So you see what brain regions take part 00:20:28.103 --> 00:20:31.009 in this whole thing of ejaculation or orgasm. 00:20:31.009 --> 00:20:34.463 00:20:34.463 --> 00:20:36.007 >> Aside from the obvious challenge 00:20:36.007 --> 00:20:38.881 facing the volunteers to reach orgasm in a laboratory 00:20:38.881 --> 00:20:41.687 setting, there is a time constraint, too. 00:20:42.517 --> 00:20:46.120 The oxygen tracer has a half-life of just two minutes. 00:20:46.120 --> 00:20:48.258 00:20:48.258 --> 00:20:50.061 >> I think would be tough to have an orgasm 00:20:50.061 --> 00:20:51.143 under these circumstances, 00:20:51.143 --> 00:20:52.760 under any of these circumstances. 00:20:52.760 --> 00:20:55.378 Everywhere in the world we have the vast majority 00:20:55.378 --> 00:20:59.348 of our sex in private unlike almost all other animals. 00:20:59.348 --> 00:21:00.158 00:21:00.158 --> 00:21:03.253 >> Fortunately, 11 men and 13 women did manage 00:21:03.253 --> 00:21:05.599 to get the timing just right. 00:21:06.307 --> 00:21:08.231 And what this ground-breaking experiment 00:21:08.231 --> 00:21:10.804 revealed was a startling difference between 00:21:10.804 --> 00:21:13.743 male and female brain activity during sex. 00:21:14.404 --> 00:21:16.350 >> The outcome was very surprising. 00:21:16.350 --> 00:21:20.365 When you look at the male brain during ejaculation 00:21:20.365 --> 00:21:24.213 or orgasm then you see several parts activate. 00:21:24.890 --> 00:21:27.974 >> During male orgasm, blood gushes to the top 00:21:27.974 --> 00:21:29.418 of the brain stem. 00:21:29.772 --> 00:21:31.758 As well as being one of the oldest parts 00:21:31.758 --> 00:21:34.132 of the human brain, it's the area that controls 00:21:34.132 --> 00:21:36.721 the release of dopamine across the brain. 00:21:37.397 --> 00:21:39.281 Dopamine is a type of hormone 00:21:39.281 --> 00:21:41.443 called a neurotransmitter. 00:21:41.443 --> 00:21:44.045 Scientists know dopamine generates very strong 00:21:44.045 --> 00:21:46.311 feelings we associate with pleasure. 00:21:46.311 --> 00:21:47.797 00:21:47.797 --> 00:21:49.633 >> What became clear is that the dopamine 00:21:49.633 --> 00:21:53.338 is released a little bit in advance of these things 00:21:53.338 --> 00:21:55.694 like food and sex and drugs. 00:21:55.694 --> 00:21:58.017 So it's not strictly speaking of a chemical 00:21:58.017 --> 00:22:00.657 of pleasure, it's a chemical of anticipation. 00:22:00.657 --> 00:22:01.927 00:22:01.927 --> 00:22:04.854 >> So, you're getting a flood of dopamine. 00:22:04.854 --> 00:22:06.857 Dopamine is the same chemical that becomes 00:22:06.857 --> 00:22:09.166 active when you feel the rush of cocaine 00:22:09.166 --> 00:22:11.187 and the other stimulant drugs so it is an 00:22:11.187 --> 00:22:15.171 overwhelming experience of ecstasy and energy. 00:22:15.878 --> 00:22:18.193 >> The experiment showed that in men, 00:22:18.193 --> 00:22:20.659 blood was flowing away from areas of the brain 00:22:20.659 --> 00:22:23.861 that had to do with anxiety but other areas 00:22:23.861 --> 00:22:25.290 remained alert. 00:22:25.290 --> 00:22:25.876 00:22:25.876 --> 00:22:29.822 >> In men, you will find deactivation of the amygdala 00:22:29.822 --> 00:22:33.689 and the region that has to do with anxiety 00:22:33.689 --> 00:22:34.818 or fear. 00:22:34.818 --> 00:22:37.574 >> It is not surprising that other parts of the brain 00:22:37.574 --> 00:22:40.630 become deactivated so that you don't feel 00:22:40.630 --> 00:22:42.211 anxious, you don't feel scared, 00:22:42.211 --> 00:22:43.968 you're not thinking about anything 00:22:43.968 --> 00:22:45.405 except the orgasm. 00:22:45.928 --> 00:22:48.681 >> Dr. Holstege found that women enjoy a similar 00:22:48.681 --> 00:22:51.926 dopamine experience to men but what surprises 00:22:51.926 --> 00:22:54.899 him the most is how much a woman's brain shuts 00:22:54.899 --> 00:22:56.567 down during orgasm. 00:22:56.567 --> 00:22:59.443 >> The deactivation was the most important finding. 00:22:59.443 --> 00:23:03.002 In women there was an enormous deactivation 00:23:03.002 --> 00:23:06.227 of all the centers of the brain that had to do with 00:23:06.227 --> 00:23:09.088 anxiety and fear, alertness. 00:23:09.350 --> 00:23:12.287 Apparently, women let it go. 00:23:12.287 --> 00:23:15.380 >> Women can even go unconscious during orgasm 00:23:15.380 --> 00:23:17.499 whereas men don't. 00:23:17.499 --> 00:23:19.380 Experts believe the difference between men and 00:23:19.380 --> 00:23:22.129 women may date back to prehistoric times 00:23:22.129 --> 00:23:24.868 when we were hunter-gatherers. 00:23:24.868 --> 00:23:28.316 >> This may have an evolutionary purpose. 00:23:28.316 --> 00:23:30.299 For millions of years we had our sex 00:23:30.299 --> 00:23:32.417 on the grasslands of Africa where there were 00:23:32.417 --> 00:23:34.177 dangerous animals roaming around. 00:23:34.177 --> 00:23:36.927 Somebody had to be alert enough to jump up 00:23:36.927 --> 00:23:39.661 and run or defend the group and it's logical that 00:23:39.661 --> 00:23:40.687 that would be men. 00:23:40.687 --> 00:23:43.470 So the female brain tends to shut down 00:23:43.470 --> 00:23:45.153 more than the male brain does. 00:23:45.153 --> 00:23:47.669 00:23:47.669 --> 00:23:49.333 >> In a future set of tests, 00:23:49.333 --> 00:23:52.050 Dr. Holstege hopes to increase the time he can 00:23:52.050 --> 00:23:54.632 monitor what happens in our brains during sex. 00:23:54.632 --> 00:23:56.284 00:23:56.284 --> 00:23:58.478 He's intrigued to see how rapidly the 00:23:58.478 --> 00:24:01.415 dopamine-induced feeling of euphoria drops away 00:24:01.415 --> 00:24:02.713 after orgasm. 00:24:03.251 --> 00:24:05.223 >> I still think that there will be big differences 00:24:05.223 --> 00:24:08.235 between men and women just before, during, 00:24:08.235 --> 00:24:10.610 and after orgasm. 00:24:10.610 --> 00:24:12.930 What exactly then is the difference in the brain? 00:24:12.930 --> 00:24:14.502 And that is what I want to know. 00:24:14.502 --> 00:24:16.616 00:24:16.616 --> 00:24:19.480 >> Aside from sex, dopamine plays a major role 00:24:19.480 --> 00:24:22.230 in motivating our brains to do all kinds of things. 00:24:22.230 --> 00:24:25.218 Even something that seems the opposite of sex, 00:24:25.218 --> 00:24:26.899 not furthering life, 00:24:26.899 --> 00:24:30.508 00:24:30.508 --> 00:24:31.887 but risking it. 00:24:31.887 --> 00:24:38.041 00:24:38.041 --> 00:24:40.591 What is it about the pursuit of pleasure that would 00:24:40.591 --> 00:24:43.428 make these base jumpers in Moab, Utah 00:24:43.428 --> 00:24:45.608 want to throw themselves off of a cliff? 00:24:45.608 --> 00:24:48.510 >> Pretty much all the cliffs out here have a pretty 00:24:48.510 --> 00:24:50.557 high danger scale. 00:24:50.557 --> 00:24:53.473 On a one to ten, they're all about an eight. 00:24:53.473 --> 00:24:55.613 >> Mistakes can be fatal. 00:24:55.613 --> 00:24:57.576 00:24:57.576 --> 00:24:59.054 >> When you run off a 500 foot rock, 00:24:59.054 --> 00:25:01.326 you've got about six seconds to live 00:25:01.326 --> 00:25:02.486 and is that extreme? 00:25:02.486 --> 00:25:04.745 Yeah, you're darned right that's extreme. 00:25:05.669 --> 00:25:07.480 >> And if this is the ultimate thrill for some 00:25:07.480 --> 00:25:10.511 people's brains, why not for everyone's? 00:25:11.218 --> 00:25:14.071 >> This thrill is just basically essential 00:25:14.071 --> 00:25:15.806 for us to be happy. 00:25:15.806 --> 00:25:19.407 To have that feeling alive inside of you 00:25:19.407 --> 00:25:21.632 so then life is worth it. 00:25:21.632 --> 00:25:26.719 00:25:26.719 --> 00:25:29.984 >> Science tells us that as a base jumper is thinking 00:25:29.984 --> 00:25:32.405 about the jump their brain begins releasing 00:25:32.405 --> 00:25:33.736 dopamine. 00:25:33.736 --> 00:25:36.402 As with sex, dopamine plays the role of building 00:25:36.402 --> 00:25:37.879 anticipation. 00:25:37.879 --> 00:25:38.993 But unlike sex, 00:25:38.993 --> 00:25:41.437 the amygdala doesn't shut down. 00:25:41.437 --> 00:25:44.008 Instead, it is sending out fear signals. 00:25:44.008 --> 00:25:46.016 00:25:46.016 --> 00:25:48.161 >> Before a jump I'll get the jitters and I will get 00:25:48.161 --> 00:25:49.834 nervous and palms might get sweaty, 00:25:49.834 --> 00:25:51.821 and a million thoughts race into my mind. 00:25:51.821 --> 00:25:53.817 00:25:53.817 --> 00:25:56.321 >> Most of your mental preparation is, 00:25:56.321 --> 00:25:58.770 OK, what if my parachute opens backwards? 00:25:58.770 --> 00:26:01.224 What if I have a problem with one of my toggles? 00:26:01.224 --> 00:26:04.098 00:26:04.098 --> 00:26:06.439 >> Even though the jumpers are focused on the jump 00:26:06.439 --> 00:26:09.613 itself, you know, what they might not realize 00:26:09.613 --> 00:26:12.074 is that the dopamine kick is happening all along 00:26:12.074 --> 00:26:13.655 during this process. 00:26:13.655 --> 00:26:17.710 00:26:17.710 --> 00:26:20.609 >> Kresta Christensen is a newcomer to base jumping. 00:26:21.101 --> 00:26:23.652 >> I'm feeling excited. 00:26:23.652 --> 00:26:26.156 My heart is going a little bit faster 00:26:26.156 --> 00:26:27.598 because I know that the gear check means 00:26:27.598 --> 00:26:29.516 that it's getting a little bit closer. 00:26:29.516 --> 00:26:32.263 00:26:32.263 --> 00:26:32.911 Three. 00:26:32.911 --> 00:26:33.673 Two. 00:26:33.673 --> 00:26:34.413 One. 00:26:34.413 --> 00:26:35.350 See ya. 00:26:35.350 --> 00:26:36.836 Ohh, I get so nervous! 00:26:36.836 --> 00:26:37.745 (laughing) 00:26:39.361 --> 00:26:42.992 It is unlike anything else that I've ever done. 00:26:42.992 --> 00:26:45.245 Especially for someone that's scared of heights. 00:26:46.337 --> 00:26:49.057 >> Kresta is nervous because her amygdala, 00:26:49.057 --> 00:26:50.980 where she harbors her fear of heights, 00:26:50.980 --> 00:26:53.296 is pressing the panic button at the site of a 00:26:53.296 --> 00:26:55.105 400 foot drop. 00:26:56.151 --> 00:26:58.220 >> Ahh!

00:36:44.248 --> 00:36:45.071 00:36:45.071 --> 00:36:47.778 So, there's no shortage of potential test subjects 00:36:47.778 --> 00:36:50.645 where Dr. Kiehl carries out his research. 00:36:50.645 --> 00:36:53.574 His aim is to develop new treatments 00:36:53.574 --> 00:36:55.774 but to do that he needs to find out what's 00:36:55.774 --> 00:36:57.698 different about their brains. 00:36:58.406 --> 00:37:02.106 >> The ideal goal is to be able to help us reduce 00:37:02.106 --> 00:37:04.314 the impact the disorder has not only on the individual 00:37:04.314 --> 00:37:05.636 but also on society. 00:37:06.082 --> 00:37:08.657 >> First he interviews the prisoners to identify 00:37:08.657 --> 00:37:11.265 those that exhibit psychopathic tendencies. 00:37:11.265 --> 00:37:11.856 00:37:11.856 --> 00:37:13.372 >> So this is going to be an interview that we kind of 00:37:13.372 --> 00:37:15.041 cover different aspects of your life. 00:37:15.041 --> 00:37:16.341 So, we're going to start out with like school history, 00:37:16.341 --> 00:37:18.440 we'll talk about employment history, 00:37:18.440 --> 00:37:19.524 we talk about your family, 00:37:19.524 --> 00:37:21.177 we'll talk about criminal activity, 00:37:21.177 --> 00:37:23.000 things that you've done, things like that. 00:37:23.000 --> 00:37:25.480 >> Psychopaths have remarkably similar patterns 00:37:25.480 --> 00:37:26.503 of behavior. 00:37:26.503 --> 00:37:27.202 00:37:27.202 --> 00:37:29.195 >> Did you ever get in trouble when you were a kid? 00:37:29.195 --> 00:37:30.571 >> All the time. 00:37:30.571 --> 00:37:33.183 >> They have an impulsive nomadic lifestyle. 00:37:33.183 --> 00:37:34.575 They move from place to place. 00:37:34.575 --> 00:37:36.075 Relationship to relationship. 00:37:36.075 --> 00:37:37.836 They're very sexually promiscuous. 00:37:37.836 --> 00:37:39.305 They tend to get themselves in trouble. 00:37:39.305 --> 00:37:48.341 00:37:48.341 --> 00:37:50.701 >> Dr. Kiehl sends the prisoners he's diagnosed 00:37:50.701 --> 00:37:53.145 as psychopathic for brain scans. 00:37:54.145 --> 00:37:56.794 In the first test he wants to see how they react 00:37:56.794 --> 00:37:58.077 to making mistakes. 00:37:58.077 --> 00:37:58.793 00:37:58.793 --> 00:38:02.227 >> I've scanned over 300 inmates so we've actually 00:38:02.227 --> 00:38:03.988 collected one of the largest brain imaging data 00:38:03.988 --> 00:38:06.011 sets in the world and by far and away the largest 00:38:06.011 --> 00:38:07.941 brain imaging data set that's ever been 00:38:07.941 --> 00:38:09.734 collected in psychopaths. 00:38:09.734 --> 00:38:10.879 00:38:10.879 --> 00:38:13.056 >> All right, this is obviously the magnet. 00:38:13.056 --> 00:38:15.002 It doesn't sound like much now but it will get 00:38:15.002 --> 00:38:16.117 very, very loud. 00:38:16.117 --> 00:38:19.547 00:38:19.547 --> 00:38:22.063 >> The scanner uses magnetic fields and radio 00:38:22.063 --> 00:38:24.814 energy to monitor blood flow in the brain while 00:38:24.814 --> 00:38:27.430 the inmate is thinking and reacting. 00:38:28.693 --> 00:38:30.507 >> During this test you are going to see a series of 00:38:30.507 --> 00:38:32.083 X's and K's on the screen. 00:38:32.083 --> 00:38:34.260 What I want you to do is press the first button 00:38:34.260 --> 00:38:36.532 with your first index finger whenever an X appears 00:38:36.532 --> 00:38:38.339 on the screen but do not press 00:38:38.339 --> 00:38:40.300 when a K appears on the screen. 00:38:40.300 --> 00:38:41.353 >> All right. 00:38:41.353 --> 00:38:47.095 00:38:47.095 --> 00:38:49.224 >> The two letters flash by so quickly 00:38:49.224 --> 00:38:51.529 that the challenge is near impossible for anyone 00:38:51.529 --> 00:38:52.613 to get right. 00:38:52.613 --> 00:38:53.451 00:38:53.451 --> 00:38:55.043 >> It is very difficult, people tend to make a lot 00:38:55.043 --> 00:38:55.758 of mistakes. 00:38:55.758 --> 00:38:56.688 They tend to press buttons when they're not 00:38:56.688 --> 00:38:58.650 supposed to and what we want to know is how does 00:38:58.650 --> 00:39:00.549 their brain learn to appreciate a mistake 00:39:00.549 --> 00:39:03.573 and does it recover from that mistake? 00:39:03.573 --> 00:39:05.922 >> By observing brain activity during this test, 00:39:05.922 --> 00:39:08.702 Dr. Kiehl can see that psychopaths don't care 00:39:08.702 --> 00:39:10.694 as much as normal individuals when they 00:39:10.694 --> 00:39:11.594 make a mistake. 00:39:11.594 --> 00:39:14.637 00:39:14.637 --> 00:39:17.229 But that doesn't mean they're unintelligent. 00:39:19.319 --> 00:39:21.650 Serial killer, Joel Rifkin for example, 00:39:21.650 --> 00:39:24.841 has an IQ of 128 which places him in the 00:39:24.841 --> 00:39:27.065 top three percent of the population. 00:39:28.200 --> 00:39:30.038 >> What's really kind of dumbfounding is that 00:39:30.038 --> 00:39:32.699 they're above average intelligence compared 00:39:32.699 --> 00:39:34.552 to the rest of the inmate population. 00:39:34.552 --> 00:39:35.959 They're very hot headed and impulsive 00:39:35.959 --> 00:39:38.234 but they are very manipulative and conning. 00:39:38.234 --> 00:39:39.687 00:39:39.687 --> 00:39:42.901 >> There were times I got pulled over with bodies 00:39:42.901 --> 00:39:44.831 in the vehicle and I would lie 00:39:44.831 --> 00:39:46.807 my way out of the situation. 00:39:46.807 --> 00:39:50.232 I was basically looking for a place to dump 00:39:50.232 --> 00:39:51.808 my little package and he's - 00:39:51.808 --> 00:39:54.193 why are you wandering around suburbia? 00:39:54.193 --> 00:39:56.499 And I'm like, well I'm lost how do I get on this road? 00:39:56.499 --> 00:39:59.151 I had no idea what road I was pointing to but 00:39:59.151 --> 00:40:01.035 I had the map and I was very convincing. 00:40:01.035 --> 00:40:08.044 00:40:08.044 --> 00:40:10.288 >> In a second test, the New Mexico inmates 00:40:10.288 --> 00:40:12.341 are asked to rate photos on whether they are 00:40:12.341 --> 00:40:14.424 morally objectionable. 00:40:14.840 --> 00:40:17.105 >> A moral volition is an action or an attitude 00:40:17.105 --> 00:40:19.051 that is considered to be wrong. 00:40:19.051 --> 00:40:20.597 You should make your decision based on your own 00:40:20.597 --> 00:40:22.640 system of moral values not what you think 00:40:22.640 --> 00:40:24.779 others or society would consider to be wrong. 00:40:24.779 --> 00:40:26.125 Does that make sense so far? 00:40:26.125 --> 00:40:26.855 >> Yeah. 00:40:26.855 --> 00:40:27.785 >> OK. 00:40:27.785 --> 00:40:31.121 00:40:31.121 --> 00:40:32.606 >> We're trying to understand how inmates 00:40:32.606 --> 00:40:35.278 process information that has a moral value. 00:40:35.278 --> 00:40:36.962 And there are different brain systems that we 00:40:36.962 --> 00:40:38.800 believe are deciding whether or not something 00:40:38.800 --> 00:40:41.039 is a moral violation or not and whether or not 00:40:41.039 --> 00:40:43.031 those systems have not developed normally 00:40:43.031 --> 00:40:44.391 in a psychopathic inmate. 00:40:44.684 --> 00:40:46.815 >> This pioneering research is proving what 00:40:46.815 --> 00:40:48.791 scientists have wondered for years. 00:40:48.791 --> 00:40:49.105 00:40:49.105 --> 00:40:51.893 Whether psychopaths have an impaired ability 00:40:51.893 --> 00:40:53.608 to reason. 00:40:53.608 --> 00:40:56.182 What they found is that their frontal lobes, 00:40:56.182 --> 00:40:58.066 the brain's most recent addition, 00:40:58.066 --> 00:40:59.504 and the amygdala, 00:40:59.504 --> 00:41:01.388 one of the more primal parts of the brain, 00:41:01.388 --> 00:41:03.257 are not communicating properly. 00:41:03.257 --> 00:41:04.279 00:41:04.279 --> 00:41:06.010 What's more, in a recent study, 00:41:06.010 --> 00:41:08.492 Dr. Adrain Raine found that the brains 00:41:08.492 --> 00:41:11.003 of psychopaths are physically different. 00:41:11.003 --> 00:41:14.035 He was able to show for the first time that they have 00:41:14.035 --> 00:41:15.427 a shrunken amygdala. 00:41:15.427 --> 00:41:18.768 On average, 17 percent smaller than most people's. 00:41:20.215 --> 00:41:22.707 And this is another crucial piece of the puzzle 00:41:22.707 --> 00:41:24.867 in understanding why psychopaths are not 00:41:24.867 --> 00:41:26.828 afraid to commit evil acts. 00:41:26.828 --> 00:41:28.158 00:41:28.158 --> 00:41:30.836 >> Psychopaths know it's wrong to kill someone 00:41:31.512 --> 00:41:32.780 but why do they do it? 00:41:32.780 --> 00:41:36.080 They don't have the feeling of what's moral. 00:41:36.080 --> 00:41:37.980 I'm not going to stick a knife in you 00:41:37.980 --> 00:41:40.287 because I'll feel the pain myself. 00:41:40.287 --> 00:41:41.510 I'll experience the pain. 00:41:41.510 --> 00:41:42.517 I've got empathy. 00:41:42.517 --> 00:41:44.617 I can put myself into your shoes. 00:41:44.617 --> 00:41:48.667 00:41:48.667 --> 00:41:51.366 Murderers like Joel Rifkin can't do that. 00:41:51.366 --> 00:41:54.162 He killed those prostitutes because he didn't 00:41:54.162 --> 00:41:59.007 care about what it might feel like to be strangled. 00:41:59.640 --> 00:42:02.739 >> How did you feel while you were strangling them? 00:42:02.739 --> 00:42:05.686 00:42:05.686 --> 00:42:08.730 >> Uh, just intensely focused on that. 00:42:08.730 --> 00:42:11.870 00:42:11.870 --> 00:42:16.893 And, uh, not thinking about much or much else. 00:42:17.708 --> 00:42:20.240 >> Rifkin committed so many murders he was bound 00:42:20.240 --> 00:42:22.429 to get caught eventually. 00:42:22.429 --> 00:42:24.563 But what about all those other psychopaths, 00:42:24.563 --> 00:42:25.939 that one in one hundred, 00:42:25.939 --> 00:42:27.977 why don't they end up in jail? 00:42:27.977 --> 00:42:31.755 00:42:31.755 --> 00:42:34.130 Dr. Raine's research has pinpointed the difference 00:42:34.130 --> 00:42:36.809 in the brains of white collar psychopaths. 00:42:37.372 --> 00:42:39.431 The kind who think nothing of swindling people 00:42:39.431 --> 00:42:40.961 out of their life's savings. 00:42:40.961 --> 00:42:41.891 00:42:41.891 --> 00:42:44.028 Yes, they have the smaller amygdala but it 00:42:44.028 --> 00:42:46.051 appears to communicate with their frontal lobes 00:42:46.051 --> 00:42:47.180 normally. 00:42:47.180 --> 00:42:49.692 00:42:49.692 --> 00:42:51.928 They have less capacity for empathy but 00:42:51.928 --> 00:42:55.695 have the brainpower to be a good liar and a cheat. 00:42:55.695 --> 00:42:58.297 Successful psychopaths showed very good 00:42:58.297 --> 00:42:59.889 executive functions. 00:42:59.889 --> 00:43:01.819 Very good planning ability. 00:43:01.819 --> 00:43:04.640 Very good ability to regulate and control. 00:43:04.640 --> 00:43:07.503 They have good awareness of themselves. 00:43:07.503 --> 00:43:10.431 They have very good stress reactivity. 00:43:10.431 --> 00:43:13.244 And frankly, you need these executive functions 00:43:13.244 --> 00:43:16.708 to successfully con and manipulate individuals. 00:43:16.708 --> 00:43:17.868 00:43:17.868 --> 00:43:20.076 With scientists now sure that psychopaths 00:43:20.076 --> 00:43:23.842 have impaired brains, it begs the question of 00:43:23.842 --> 00:43:25.218 when they go wrong? 00:43:25.218 --> 00:43:28.697 00:43:28.697 --> 00:43:31.257 >> We believe that in large part the feeling 00:43:31.257 --> 00:43:34.392 of what's right and wrong is wired into the brain. 00:43:34.392 --> 00:43:37.586 The brain is set to be somewhat less moral 00:43:37.586 --> 00:43:42.222 or more moral depending on your genetic 00:43:42.222 --> 00:43:44.821 and your biological background. 00:43:44.821 --> 00:43:47.198 >> In other words, it's in our genes. 00:43:47.198 --> 00:43:49.530 And it's how our brain grows in the womb. 00:43:49.530 --> 00:43:51.460 But according to Dr. Raine, 00:43:51.460 --> 00:43:53.396 that's still only half the story. 00:43:53.847 --> 00:43:55.823 >> Of course you can't rule out the environment, 00:43:55.823 --> 00:43:58.648 that's 50 percent of the equation. 00:43:58.648 --> 00:44:00.178 It's like two sides of a coin, 00:44:00.178 --> 00:44:03.031 it's both genetic and environmental. 00:44:03.830 --> 00:44:06.230 >> If finding the location of good and evil 00:44:06.230 --> 00:44:08.584 in the brain has been a challenge for scientists, 00:44:08.584 --> 00:44:11.012 there is an even bigger mystery waiting 00:44:11.012 --> 00:44:14.228 to be unlocked - memory. 00:44:14.228 --> 00:44:15.389 Thanks to memory, 00:44:15.389 --> 00:44:17.618 the brain is constantly traveling through 00:44:17.618 --> 00:44:19.533 time, pulling fragments of the past 00:44:19.533 --> 00:44:21.494 into the present. 00:44:21.494 --> 00:44:24.434 This ability is key to a human's existence. 00:44:24.434 --> 00:44:26.557 >> The reason we have memory is so that you can 00:44:26.557 --> 00:44:29.565 make better decisions the next time around. 00:44:29.565 --> 00:44:32.690 So, all of your thinking and your future planning 00:44:32.690 --> 00:44:34.865 is dictated by your memory. 00:44:35.818 --> 00:44:37.708 >> While the workings of an organ like the heart 00:44:37.708 --> 00:44:41.162 are well understood, scientists are still figuring out 00:44:41.162 --> 00:44:43.431 memory in the brain. 00:44:43.431 --> 00:44:46.278 The big breakthrough came 80 years ago. 00:44:46.278 --> 00:44:47.854 00:44:47.854 --> 00:44:48.969 >> So in the 1920's, 00:44:48.969 --> 00:44:51.195 a neuroscientist named Karl Lashley, 00:44:51.195 --> 00:44:52.864 taught rats to run a maze. 00:44:52.864 --> 00:44:55.769 And then he damaged parts of their brains 00:44:55.769 --> 00:44:58.277 selectively to see where the memory of how to 00:44:58.277 --> 00:45:00.084 run the maze was stored. 00:45:00.084 --> 00:45:03.076 Now what he found is that it is not stored 00:45:03.076 --> 00:45:04.514 in any particular place. 00:45:05.128 --> 00:45:06.858 And you have an extremely complicated, 00:45:06.858 --> 00:45:08.388 very networked system. 00:45:08.388 --> 00:45:09.257 00:45:09.257 --> 00:45:11.049 >> The system is so complex in fact, 00:45:11.049 --> 00:45:12.918 the most advanced super computers don't 00:45:12.918 --> 00:45:15.758 even come close to the storage capacity of the brain. 00:45:15.758 --> 00:45:16.965 00:45:16.965 --> 00:45:20.131 10 trillion bytes of memory. 00:45:20.131 --> 00:45:21.954 >> The brain is the most complicated device 00:45:21.954 --> 00:45:23.592 we've found in the universe. 00:45:23.592 --> 00:45:27.941 It has 10 billion cells just in the cortex 00:45:27.941 --> 00:45:31.577 which is the outer part and in a single tiny 00:45:31.577 --> 00:45:33.886 piece of cortex, a cubic millimeter, 00:45:33.886 --> 00:45:36.402 you have more connections than you have stars 00:45:36.402 --> 00:45:38.543 in the Milky Way Galaxy. 00:45:38.543 --> 00:45:40.631 >> All those connections make the brain capable 00:45:40.631 --> 00:45:42.577 of storing and retrieving massive amounts 00:45:42.577 --> 00:45:44.707 of data in some amazing ways. 00:45:44.707 --> 00:45:46.391 00:45:46.391 --> 00:45:48.460 Perhaps none more incredible and extreme 00:45:48.460 --> 00:45:51.031 than what's called photographic memory or 00:45:51.031 --> 00:45:52.300 mnemonism. 00:45:52.300 --> 00:45:53.646 00:45:53.646 --> 00:45:55.730 >> As we try to understand vision and memory 00:45:55.730 --> 00:45:58.834 in neuroscience, we're really fascinated by people 00:45:58.834 --> 00:45:59.995 who are mnemonists. 00:45:59.995 --> 00:46:02.485 They have a untaxable memory that can remember 00:46:02.485 --> 00:46:03.754 everything going in. 00:46:03.754 --> 00:46:04.761 00:46:04.761 --> 00:46:06.461 >> British artist Stephen Wiltshire, 00:46:06.461 --> 00:46:08.775 has this extraordinary ability. 00:46:08.775 --> 00:46:11.518 He can remember complicated cityscapes 00:46:11.518 --> 00:46:15.306 and reproduce them in staggering detail. 00:46:15.306 --> 00:46:18.023 For his latest sketch, he's climbing to the top 00:46:18.023 --> 00:46:20.969 of Tower Bridge for a bird's eye view of London. 00:46:20.969 --> 00:46:23.498 00:46:23.498 --> 00:46:25.624 He need only stay a few minutes since he claims 00:46:25.624 --> 00:46:28.408 his visual memory of the scene will never fade. 00:46:28.408 --> 00:46:31.684 00:46:31.684 --> 00:46:35.545 >> I'm just looking at the buildings and skyscrapers. 00:46:35.545 --> 00:46:38.559 Usually I like to take about 20 minutes 00:46:38.559 --> 00:46:40.969 and then do it from memory. 00:46:41.530 --> 00:46:44.373 >> To appreciate how incredible Stephen's skill is, 00:46:44.373 --> 00:46:47.360 it helps to understand how vision works. 00:46:47.360 --> 00:46:49.999 00:46:49.999 --> 00:46:52.175 Sight is processed at the back of the brain 00:46:52.175 --> 00:46:55.069 in the occipital lobes or visual cortex. 00:46:55.069 --> 00:46:55.983 00:46:55.983 --> 00:47:00.327 Two eyes give a field of vision of about 200 degrees. 00:47:00.327 --> 00:47:03.187 They can detect 2.3 million different shades 00:47:03.187 --> 00:47:04.517 of color. 00:47:04.517 --> 00:47:07.781 And experts estimate they send 72 gigabytes 00:47:07.781 --> 00:47:10.198 of information to the brain every second. 00:47:10.198 --> 00:47:11.851 00:47:11.851 --> 00:47:15.060 That's like 18,000 songs on an IPod. 00:47:15.060 --> 00:47:17.181 00:47:17.181 --> 00:47:19.326 Back at his gallery, Stephen begins to draw 00:47:19.326 --> 00:47:20.995 what he saw. 00:47:20.995 --> 00:47:23.156 He's using several areas of his brain. 00:47:23.156 --> 00:47:26.535 His parietal lobes in particular are working to 00:47:26.535 --> 00:47:28.450 control his spacial manipulation 00:47:28.450 --> 00:47:30.150 and hand-eye coordination. 00:47:30.150 --> 00:47:31.865 00:47:31.865 --> 00:47:33.703 Cross-checking his sketch with the view 00:47:33.703 --> 00:47:36.883 reveals just how uncannily accurate it is. 00:47:36.883 --> 00:47:39.150 00:47:39.150 --> 00:47:41.455 In little more than an hour he's recreated 00:47:41.455 --> 00:47:42.985 the panorama. 00:47:42.985 --> 00:47:45.997 00:47:45.997 --> 00:47:48.759 This picture will sell for $4,000. 00:47:48.759 --> 00:47:51.329 00:47:51.329 --> 00:47:54.530 Stephen's talent is almost super human. 00:47:54.530 --> 00:47:56.824 But his skill comes at a cost. 00:47:56.824 --> 00:47:58.724 He is an autistic savant 00:47:58.724 --> 00:48:01.194 which means his brain has developed differently. 00:48:01.485 --> 00:48:04.715 >> Most of us don't have the capacities he does 00:48:04.715 --> 00:48:08.162 because our brains are doing 57 other things. 00:48:08.162 --> 00:48:10.367 We're thinking about our careers, our mortgages, 00:48:10.367 --> 00:48:11.743 our futures, and what we're doing at the 00:48:11.743 --> 00:48:13.443 grocery store later on, and so on, 00:48:13.443 --> 00:48:16.487 and as a result, the neural real estate 00:48:16.487 --> 00:48:18.448 is divided up among lots of different tasks. 00:48:18.448 --> 00:48:21.075 In a savant's brain, essentially all of that 00:48:21.075 --> 00:48:23.204 real estate is devoted towards one thing like 00:48:23.204 --> 00:48:25.580 solving that Rubik's Cube or playing the piano 00:48:25.580 --> 00:48:27.587 and as a result they have they deficits in 00:48:27.587 --> 00:48:28.886 other aspects of their life. 00:48:28.886 --> 00:48:31.799 For example, in their capacity to socialize. 00:48:31.799 --> 00:48:33.067 00:48:33.067 --> 00:48:35.075 >> Geniuses like Leonardo Da Vinci, 00:48:35.075 --> 00:48:38.709 Mozart, and Monet all had incredible memories 00:48:38.709 --> 00:48:40.716 and there is speculation they may have been 00:48:40.716 --> 00:48:42.246 autistic, too. 00:48:42.246 --> 00:48:47.414 00:48:47.414 --> 00:48:49.771 While some brains can remember nearly everything 00:48:49.771 --> 00:48:52.297 they see, other brains can barely remember 00:48:52.297 --> 00:48:53.720 anything at all. 00:48:53.720 --> 00:48:55.546 00:48:55.546 --> 00:48:57.646 Welcome to the life of Clive Wearing, 00:48:57.646 --> 00:49:00.737 a man with the worst case of amnesia 00:49:00.737 --> 00:49:01.975 in the world. 00:49:01.975 --> 00:49:03.736 >> What were we doing before we sat on the bench? 00:49:03.736 --> 00:49:04.774 >> No idea. 00:49:04.774 --> 00:49:13.108 00:49:13.108 --> 00:49:16.126 >> Well! Yay! 00:49:16.126 --> 00:49:16.826 00:49:16.826 --> 00:49:18.617 Even though Clive Wearing has seen his wife, 00:49:18.617 --> 00:49:20.425 Deborah, numerous times today, 00:49:20.425 --> 00:49:23.705 every time he meets her, it's like he's seeing her 00:49:23.705 --> 00:49:24.958 for the first time. 00:49:24.958 --> 00:49:26.365 00:49:26.365 --> 00:49:29.613 Clive has the worst case of amnesia in the world. 00:49:30.404 --> 00:49:33.923 His memory span is at most 30 seconds long. 00:49:33.923 --> 00:49:35.592 00:49:35.592 --> 00:49:37.492 >> What were we doing before we sat on the bench? 00:49:37.492 --> 00:49:38.592 >> No idea. 00:49:39.791 --> 00:49:41.552 >> Do you know what this building is? 00:49:41.552 --> 00:49:42.798 >> No. 00:49:42.802 --> 00:49:43.886 >> Have you seen it before? 00:49:43.886 --> 00:49:44.755 >> No. 00:49:44.755 --> 00:49:48.149 >> He said to me it's like between before waking up 00:49:48.149 --> 00:49:49.141 and waking up. 00:49:49.141 --> 00:49:50.641 It's like the in-between stage, 00:49:50.641 --> 00:49:52.770 you haven't yet grasped where you are. 00:49:53.523 --> 00:49:55.037 What do you know? 00:49:55.037 --> 00:49:56.368 >> Nothing at all. 00:49:56.368 --> 00:49:57.760 >> Nothing? 00:49:57.760 --> 00:49:58.582 00:49:58.582 --> 00:50:00.805 >> Never had a thought or a dream. 00:50:01.974 --> 00:50:03.520 Day and night the same. 00:50:03.520 --> 00:50:04.573 >> Day and night the same? 00:50:04.573 --> 00:50:06.473 >> Yeah, blank all the time. 00:50:06.473 --> 00:50:09.565 00:50:09.565 --> 00:50:11.603 >> Clive was an acclaimed British conductor 00:50:11.603 --> 00:50:14.216 and musicologist until a viral infection 00:50:14.216 --> 00:50:17.267 developed into encephalitis in his brain. 00:50:18.205 --> 00:50:20.448 When the acute inflammation subsided, 00:50:20.448 --> 00:50:23.011 his brain had been severely damaged. 00:50:23.011 --> 00:50:24.987 00:50:24.987 --> 00:50:26.840 It's left him with only a very limited 00:50:26.840 --> 00:50:28.340 short-term memory. 00:50:28.340 --> 00:50:29.747 00:50:29.747 --> 00:50:33.724 >> Clive has absolutely no memory of anything 00:50:33.724 --> 00:50:35.814 that's happened in his life since the ambulance 00:50:35.814 --> 00:50:38.891 took him away in March 1985. 00:50:38.891 --> 00:50:41.735 And his autobiographical memory is so vague 00:50:41.735 --> 00:50:43.588 it's to be almost not there. 00:50:43.588 --> 00:50:45.226 00:50:45.226 --> 00:50:46.572 Who's that? 00:50:46.572 --> 00:50:47.872 >> I can't remember. 00:50:48.979 --> 00:50:50.694 >> That's him. 00:50:50.694 --> 00:50:51.732 >> My son. 00:50:51.732 --> 00:50:53.262 >> Your son, that's right. 00:50:53.262 --> 00:50:57.140 That's Antony and that's his children. 00:50:57.140 --> 00:50:57.808 >> His children? 00:50:57.808 --> 00:50:58.415 >> Yeah. 00:50:58.415 --> 00:50:59.422 >> I see. 00:50:59.422 --> 00:51:00.645 >> Only they're much bigger now. 00:51:00.645 --> 00:51:03.156 00:51:03.156 --> 00:51:05.344 Although memories are spread across the entire 00:51:05.344 --> 00:51:08.358 brain, there is one part that acts like a key 00:51:08.358 --> 00:51:11.158 to the storage and retrieval process, 00:51:11.158 --> 00:51:13.863 the hippocampus within the limbic system. 00:51:13.863 --> 00:51:15.270 00:51:15.270 --> 00:51:17.632 We know this because without the hippocampus, 00:51:17.632 --> 00:51:19.948 new memories do not form. 00:51:19.948 --> 00:51:21.278 There are at least two types of memory 00:51:21.278 --> 00:51:23.208 in the brain and most generally we divide that 00:51:23.208 --> 00:51:24.369 into short and long-term memory. 00:51:24.369 --> 00:51:27.342 So, short-term memory is if I tell you my 00:51:27.342 --> 00:51:28.780 phone number and you have to remember that 00:51:28.780 --> 00:51:31.156 for a few seconds while you go over to dial it. 00:51:31.156 --> 00:51:33.409 Long-term memory involves things like 00:51:33.409 --> 00:51:36.108 where you grew up and where you went to school 00:51:36.108 --> 00:51:37.377 and what you did today. 00:51:37.377 --> 00:51:38.892 That's all stored in long-term memory. 00:51:38.892 --> 00:51:40.745 What's happening with Clive is that he has a very 00:51:40.745 --> 00:51:42.321 short-term window of memory. 00:51:42.321 --> 00:51:44.067 He is not able to translate the short-term 00:51:44.067 --> 00:51:45.274 into long-term. 00:51:45.274 --> 00:51:47.817 He's not able to cement down the activity in 00:51:47.817 --> 00:51:50.078 the short-term into something in the physical 00:51:50.078 --> 00:51:51.393 structure in his brain. 00:51:51.393 --> 00:51:52.107 00:51:52.107 --> 00:51:53.899 >> Neurologists who have examined Clive 00:51:53.899 --> 00:51:57.007 have found severe damage in his hippocampus 00:51:57.007 --> 00:51:59.692 and they think that's what preventing his brain 00:51:59.692 --> 00:52:01.622 from storing memories. 00:52:01.622 --> 00:52:03.568 >> Clive Wearing suffers from both 00:52:03.568 --> 00:52:05.668 anterograde and retrograde amnesia. 00:52:05.668 --> 00:52:08.622 That is he can't learn new things but he also 00:52:08.622 --> 00:52:10.950 has a hard time recollecting old things. 00:52:10.950 --> 00:52:15.205 And it primarily seems to be affecting his ability 00:52:15.205 --> 00:52:16.843 to recollect information at will. 00:52:17.458 --> 00:52:19.746 >> Watch what happens when Clive's wife asks 00:52:19.746 --> 00:52:21.799 him what his son does for a living. 00:52:22.552 --> 00:52:25.925 >> Do you know what Antony's profession is? 00:52:25.925 --> 00:52:27.301 00:52:27.301 --> 00:52:28.677 >> He's an electrical engineer. 00:52:28.677 --> 00:52:29.407 >> Oh, is he? 00:52:29.407 --> 00:52:31.606 >> Yes. And do you know what he designs? 00:52:31.606 --> 00:52:32.644 >> No. 00:52:33.582 --> 00:52:34.774 >> Have a guess. 00:52:34.774 --> 00:52:35.335 00:52:35.335 --> 00:52:37.349 >> No idea.

It does, doesn't it? 00:52:48.664 --> 00:52:50.133 >> Yeah, that was a very disastrous idea - 00:52:50.133 --> 00:52:51.094 >> That's right. 00:52:51.094 --> 00:52:52.955 00:52:52.955 --> 00:52:54.947 Do you know anyone who designs 00:52:54.947 --> 00:52:56.385 electrical car motors? 00:52:56.385 --> 00:52:57.084 >> No, I don't. 00:52:57.084 --> 00:52:58.153 >> Do you know anyone who does that? 00:52:58.153 --> 00:52:59.306 >> No. 00:52:59.595 --> 00:53:00.525 >> Your son does. 00:53:00.525 --> 00:53:01.778 >> Oh, I see! 00:53:01.778 --> 00:53:02.831 >> Antony does. 00:53:03.877 --> 00:53:06.144 He's actually got his own business. 00:53:06.144 --> 00:53:07.213 >> Oh, well done! 00:53:07.213 --> 00:53:08.082 >> Yeah. 00:53:08.082 --> 00:53:09.551 >> Oh. 00:53:10.812 --> 00:53:13.812 >> Do you remember what Antony's doing 00:53:13.812 --> 00:53:14.358 these days? 00:53:14.358 --> 00:53:17.029 >> No idea. Still at school last time I was conscious. 00:53:17.029 --> 00:53:19.664 00:53:19.664 --> 00:53:22.381 >> What makes Clive such a unique case is that while 00:53:22.381 --> 00:53:24.796 he can't remember details about his family, 00:53:24.796 --> 00:53:27.326 he can recall other things. 00:53:27.326 --> 00:53:29.595 >> The fact that his language is preserved so well 00:53:29.595 --> 00:53:32.590 and he is articulate illustrates the procedural 00:53:32.590 --> 00:53:34.950 memory for how to speak and how to construct 00:53:34.950 --> 00:53:37.961 words is stored separately than the issues 00:53:37.961 --> 00:53:41.004 about episodic memory, what you did, the facts 00:53:41.004 --> 00:53:41.950 about your life. 00:53:41.950 --> 00:53:42.973 00:53:42.973 --> 00:53:45.039 >> Different types of memories are stored very 00:53:45.039 --> 00:53:47.015 differently in the brain. 00:53:47.015 --> 00:53:49.607 Experts believe language memory could live 00:53:49.607 --> 00:53:51.557 in one of the temporal lobes, 00:53:51.557 --> 00:53:53.364 the one responsible for sound and speech 00:53:53.364 --> 00:53:55.604 on the left side of the brain. 00:53:55.604 --> 00:53:58.777 What's even more amazing is that Clive can still 00:53:58.777 --> 00:54:00.169 play the piano. 00:54:00.169 --> 00:54:01.684 00:54:01.684 --> 00:54:03.678 His procedural memory for playing the piano, 00:54:03.678 --> 00:54:05.515 on the right side of his brain, 00:54:05.515 --> 00:54:07.091 is undamaged. 00:54:07.091 --> 00:54:15.199 00:54:15.199 --> 00:54:17.719 >> When he is performing music, 00:54:17.719 --> 00:54:21.732 that is where Clive finds a continuum. 00:54:21.732 --> 00:54:25.658 He has a momentum that kind of carries him 00:54:25.658 --> 00:54:26.850 through time. 00:54:26.850 --> 00:54:28.611 00:54:28.611 --> 00:54:30.610 >> It's a great illustration of the way that these 00:54:30.610 --> 00:54:33.110 different types of memory can be separated out. 00:54:33.494 --> 00:54:34.886 >> Do you know what month this is? 00:54:34.886 --> 00:54:35.662 >> No. 00:54:37.215 --> 00:54:38.206 >> It's April. 00:54:38.206 --> 00:54:38.828 >> April? 00:54:38.828 --> 00:54:39.774 >> Mm-hmm. 00:54:40.327 --> 00:54:41.364 It's your birthday next month. 00:54:41.364 --> 00:54:42.449 >> Yes. 00:54:42.449 --> 00:54:45.252 >> Clive today appears upbeat but that was not 00:54:45.252 --> 00:54:46.275 always the case. 00:54:46.275 --> 00:54:50.588 00:54:50.588 --> 00:54:53.511 This was Clive in 1988, three years into his 00:54:53.511 --> 00:54:56.210 amnesia when he was frustrated and angry. 00:54:56.210 --> 00:54:58.079 00:54:58.079 --> 00:55:01.134 >> For the first ten years, Clive lived in a world 00:55:01.134 --> 00:55:04.088 where he said the same few things over and 00:55:04.088 --> 00:55:08.844 over again because of the anxiety, 00:55:08.844 --> 00:55:10.205 the fear, 00:55:10.205 --> 00:55:11.166 the terror, 00:55:11.166 --> 00:55:13.600 the horror of his situation. 00:55:13.600 --> 00:55:15.768 >> Each new moment he felt he was awake 00:55:15.768 --> 00:55:17.498 he wanted to write it down. 00:55:17.498 --> 00:55:19.213 >> Well, it was such a compulsion that he would 00:55:19.213 --> 00:55:21.189 have written it on the table, 00:55:21.189 --> 00:55:22.427 on the wall, 00:55:22.427 --> 00:55:24.080 on any available surface. 00:55:24.080 --> 00:55:25.010 00:55:25.010 --> 00:55:26.402 >> So how do you think you got there? 00:55:26.402 --> 00:55:27.640 >> I don't know. 00:55:27.640 --> 00:55:28.786 I presume the doctors don't know. 00:55:28.786 --> 00:55:29.177 >> But you must have - 00:55:29.177 --> 00:55:30.293 >> No! I haven't! 00:55:30.293 --> 00:55:32.116 You listen to me please for Heaven's sake! 00:55:32.116 --> 00:55:32.585 >> Sorry. 00:55:32.585 --> 00:55:33.946 When I say no, I mean exactly that! 00:55:33.946 --> 00:55:36.479 00:55:36.479 --> 00:55:37.963 >> The pages of his diary are filled with 00:55:37.963 --> 00:55:40.823 exclamations and words crossed out. 00:55:40.823 --> 00:55:44.109 Eventually though, his anger subsided. 00:55:45.001 --> 00:55:47.070 >> He started to change 00:55:47.070 --> 00:55:50.364 after about the first 14 to 15 years. 00:55:50.364 --> 00:55:52.402 He began to remember things for longer. 00:55:52.402 --> 00:55:53.625 His mood changed. 00:55:53.625 --> 00:55:54.740 00:55:54.740 --> 00:55:56.824 >> Deborah attributes this change to her faith 00:55:56.824 --> 00:55:58.216 and her prayers. 00:55:58.216 --> 00:56:00.525 Scientists have their own explanation. 00:56:00.525 --> 00:56:02.847 >> We do know that your brain physically changes 00:56:02.847 --> 00:56:05.474 and that's what we mean by plasticity. 00:56:05.474 --> 00:56:07.574 It's always rewriting it's own circuitry. 00:56:07.574 --> 00:56:10.297 With children the brains are extremely plastic. 00:56:10.297 --> 00:56:13.023 That's why children can learn language 00:56:13.023 --> 00:56:14.491 so much more easily or learn how to play 00:56:14.491 --> 00:56:15.729 a new instrument. 00:56:15.729 --> 00:56:17.090 What we are now discovering is that the 00:56:17.090 --> 00:56:19.542 adult human brain is much more plastic than 00:56:19.542 --> 00:56:21.657 we previously thought so when people get 00:56:21.657 --> 00:56:23.982 brain damage, other parts of their brain can 00:56:23.982 --> 00:56:27.724 shift around and take over the missing functions. 00:56:27.724 --> 00:56:29.731 >> This year, Deborah wondered whether Clive 00:56:29.731 --> 00:56:31.831 still needed his diary. 00:56:31.831 --> 00:56:33.992 >> When he looks through the previous 00:56:33.992 --> 00:56:37.461 days and weeks and months and saw that he'd 00:56:37.461 --> 00:56:39.845 just written the same thing over and over again, 00:56:39.845 --> 00:56:43.198 it tended to upset him and we thought, 00:56:43.198 --> 00:56:44.990 well, let's just take it away and see whether 00:56:44.990 --> 00:56:46.058 he misses it. 00:56:46.058 --> 00:56:48.545 >> To everyone's surprise, after writing in his 00:56:48.545 --> 00:56:51.150 diary every single day for 23 years, 00:56:51.150 --> 00:56:53.925 Clive didn't ask for it back. 00:56:53.925 --> 00:56:56.085 That compulsive need to record each moment 00:56:56.085 --> 00:56:58.292 of awakening must have passed. 00:56:58.292 --> 00:57:01.391 00:57:01.391 --> 00:57:03.522 Scientists have learned a lot about memory by 00:57:03.522 --> 00:57:04.991 studying Clive. 00:57:04.991 --> 00:57:05.891 00:57:05.891 --> 00:57:07.714 But they've also gained valuable insight on 00:57:07.714 --> 00:57:09.275 other brain functions that contribute 00:57:09.275 --> 00:57:10.775 to a person's identity. 00:57:10.775 --> 00:57:12.228 00:57:12.228 --> 00:57:14.851 >> A lot of people say memory makes us who we are 00:57:14.851 --> 00:57:18.853 and boy did I find out how wrong that was. 00:57:18.853 --> 00:57:21.320 Clive's personality, thank God, 00:57:21.320 --> 00:57:22.758 is intact. 00:57:22.758 --> 00:57:23.765 >> Fancy a cup of coffee? 00:57:23.765 --> 00:57:26.729 >> Oh, I'd love it! That would be marvelous! 00:57:26.729 --> 00:57:28.044 >> I thought you'd be pleased. 00:57:28.044 --> 00:57:30.036 He's funny. 00:57:30.036 --> 00:57:31.951 He's also very compassionate. 00:57:31.951 --> 00:57:33.881 >> Lead the way to Heaven on earth. 00:57:33.881 --> 00:57:35.596 He has no knowledge about himself. 00:57:35.596 --> 00:57:37.753 But he is who he is. 00:57:37.753 --> 00:57:39.406 Unchanged. 00:57:39.406 --> 00:57:40.706 Pure Clive. 00:57:40.706 --> 00:57:42.206 00:57:42.206 --> 00:57:45.246 >> Memory plays a pivotal role in everything we do 00:57:45.246 --> 00:57:47.130 including sports. 00:57:47.130 --> 00:57:50.312 It's finally dawning on athletes that it's not only 00:57:50.312 --> 00:57:53.588 brawn but also brain that makes a champion. 00:57:53.588 --> 00:57:54.364 00:57:54.364 --> 00:57:56.660 >> Well, in the 80's we developed a lot of muscle 00:57:56.660 --> 00:57:59.328 training methods to increase sports performance. 00:57:59.328 --> 00:58:01.411 And now, in the 21st Century, 00:58:01.411 --> 00:58:03.658 we're taking the brain to the weight room. 00:58:03.658 --> 00:58:09.099 00:58:09.099 --> 00:58:13.166 (Commercials) 00:58:13.166 --> 01:01:25.996 01:01:25.996 --> 01:01:28.003 >> The more we learn about the brain, 01:01:28.003 --> 01:01:30.987 the more it informs every aspect of our lives 01:01:30.987 --> 01:01:33.565 including professional sports. 01:01:33.565 --> 01:01:39.793 01:01:39.793 --> 01:01:41.800 >> Sports performance is all about the brain 01:01:41.800 --> 01:01:43.823 but it wasn't like that all that time. 01:01:43.823 --> 01:01:46.596 For a long part of history of sports, 01:01:46.596 --> 01:01:48.249 people didn't care about the brain. 01:01:48.249 --> 01:01:50.272 They would consider an athlete a good player 01:01:50.272 --> 01:01:53.444 if they had good muscle definition and they were 01:01:53.444 --> 01:01:55.625 very coordinated. 01:01:55.625 --> 01:01:56.848 Just within the last ten years, 01:01:56.848 --> 01:02:00.963 we think that about 50% of all sports performance, 01:02:00.963 --> 01:02:02.647 and sometimes the most important part, 01:02:02.647 --> 01:02:04.885 that elite performance, 01:02:04.885 --> 01:02:07.331 is related to brain functioning. 01:02:07.331 --> 01:02:09.596 >> Now, athletes have caught on to how important 01:02:09.596 --> 01:02:12.420 the brain is to their performance on the field. 01:02:12.774 --> 01:02:16.324 >> 90% is mental, it's a tough game, ya know? 01:02:16.324 --> 01:02:18.224 You really have to have control of your mind 01:02:18.224 --> 01:02:19.462 to play this game. 01:02:19.462 --> 01:02:20.300 01:02:20.300 --> 01:02:22.580 >> So, how does the brain improve the game? 01:02:22.580 --> 01:02:25.841 >> Almost all of sports is dynamic and requires 01:02:25.841 --> 01:02:28.351 millisecond to millisecond decision making 01:02:28.351 --> 01:02:31.566 and if you miss it by a small percentage, 01:02:31.566 --> 01:02:33.791 you miss the put. 01:02:33.791 --> 01:02:36.541 You're a tenth of a second too slow. 01:02:36.541 --> 01:02:39.651 Your shot falls off the rim. 01:02:39.651 --> 01:02:42.040 That's that little differentiation between 01:02:42.040 --> 01:02:45.098 super world class and good. 01:02:45.098 --> 01:02:48.135 >> At a basic level, it's about hand-eye coordination 01:02:48.135 --> 01:02:50.711 and practice, practice, practice. 01:02:50.711 --> 01:02:51.595 01:02:51.595 --> 01:02:53.838 And there's no better place to see this than at the 01:02:53.838 --> 01:02:55.814 Cirque du Soleil where performers NOTE Paragraph 01:02:55.814 --> 01:02:57.944 must practice constantly. 01:02:57.944 --> 01:03:03.856 01:03:03.856 --> 01:03:06.077 We use our frontal lobes to learn how to carry 01:03:06.077 --> 01:03:08.688 out an activity but the area of the brain that 01:03:08.688 --> 01:03:11.880 benefits most from practice is the cerebellum, 01:03:11.880 --> 01:03:13.487 at the back of the brain. 01:03:13.487 --> 01:03:16.980 01:03:16.980 --> 01:03:19.134 It helps to think of the brain as an old house 01:03:19.134 --> 01:03:22.846 with new rooms slowly added over time. 01:03:22.846 --> 01:03:24.992 The brain stem is the basement because 01:03:24.992 --> 01:03:26.738 it evolved first. 01:03:26.738 --> 01:03:28.591 The cerebellum came next. 01:03:28.591 --> 01:03:30.121 >> It's an old part of the brain, 01:03:30.121 --> 01:03:31.682 it's sort of set off, off the first floor 01:03:31.682 --> 01:03:33.012 in the basement. 01:03:33.012 --> 01:03:35.705 It's almost entirely responsible for movement, 01:03:35.705 --> 01:03:38.417 complicated sequencing of movements. 01:03:38.417 --> 01:03:40.409 >> The cerebellum sends out signals to the 01:03:40.409 --> 01:03:43.130 100 billion nerve cells in our bodies 01:03:43.130 --> 01:03:45.316 which in turn tell the muscles what we want 01:03:45.316 --> 01:03:46.262 them to do. 01:03:46.262 --> 01:03:48.946 01:03:48.946 --> 01:03:51.199 >> The frontal lobe is monitoring the activity 01:03:51.199 --> 01:03:53.898 but most of the time gets out of the way 01:03:53.898 --> 01:03:56.790 and allows the cerebellum and the rest of brain 01:03:56.790 --> 01:03:59.889 to engage in this behavior that's been practiced 01:03:59.889 --> 01:04:02.012 over and over and over again. 01:04:02.012 --> 01:04:03.619 >> Scientists think that the frontal lobe 01:04:03.619 --> 01:04:05.334 simply cannot keep up with the speed 01:04:05.334 --> 01:04:07.855 of information processing necessary to perform a 01:04:07.855 --> 01:04:09.539 high level skill. 01:04:09.539 --> 01:04:11.873 01:04:11.873 --> 01:04:14.222 Which is why the cerebellum takes over. 01:04:14.222 --> 01:04:16.291 Its procedural memory, the same kind 01:04:16.291 --> 01:04:19.658 Clive Wearing uses to play the piano. 01:04:19.658 --> 01:04:22.848 >> It's the idea that you can go into a filing cabinet 01:04:22.848 --> 01:04:24.855 and pick out a motor memory that you've 01:04:24.855 --> 01:04:26.278 already practiced. 01:04:26.278 --> 01:04:29.926 >> And experts now know why practice makes perfect. 01:04:29.926 --> 01:04:32.273 The more you practice, the better the cerebellum 01:04:32.273 --> 01:04:34.326 becomes at knowing exactly which nerves 01:04:34.326 --> 01:04:36.644 and muscles to trigger each time. 01:04:36.644 --> 01:04:38.436 01:04:38.436 --> 01:04:40.597 >> In sports psychology there's suggestions that it 01:04:40.597 --> 01:04:44.050 takes 10,000 hours of deliberate practice 01:04:44.050 --> 01:04:46.858 in order to achieve the level of expertise. 01:04:46.858 --> 01:04:48.019 01:04:48.019 --> 01:04:49.984 >> Such extreme levels of ability may actually 01:04:49.984 --> 01:04:52.718 lead to memory within the muscle itself 01:04:52.718 --> 01:04:56.036 guiding a sequence of contractions and relaxations 01:04:56.036 --> 01:04:59.295 but the brain is still essential. 01:04:59.295 --> 01:05:02.588 >> You damage your brain, there is very little activity. 01:05:02.588 --> 01:05:04.800 Of course you need an intact body. 01:05:04.800 --> 01:05:07.052 You need physiology that works. 01:05:08.867 --> 01:05:10.967 In basketball it helps to be tall. 01:05:10.967 --> 01:05:13.381 In racing horses it helps to be small. 01:05:13.381 --> 01:05:15.861 But every of those athletes has a brain 01:05:15.861 --> 01:05:17.130 that has to be synchronized 01:05:17.130 --> 01:05:19.106 with their athletic activity. 01:05:19.106 --> 01:05:20.021 01:05:20.021 --> 01:05:21.936 >> But beyond practice and having the right body 01:05:21.936 --> 01:05:25.183 type, the brain plays another vital role in sports. 01:05:25.183 --> 01:05:29.642 01:05:29.642 --> 01:05:33.171 Just imagine a weight lifter who's trying to lift 01:05:33.171 --> 01:05:35.849 an amazing amount of weights. 01:05:35.849 --> 01:05:38.178 They have to be extremely pumped up. 01:05:39.039 --> 01:05:41.062 >> The navy seals use a breathing technique 01:05:41.062 --> 01:05:43.773 to calm down whereas athletes need to vary 01:05:43.773 --> 01:05:45.811 their level of excitement. 01:05:45.811 --> 01:05:47.880 Sports scientists call this process 01:05:47.880 --> 01:05:50.152 arousal modulation. 01:05:51.014 --> 01:05:54.341 >> We think of arousal modulation as the volume button 01:05:54.341 --> 01:05:55.948 of the brain. 01:05:55.948 --> 01:05:58.703 >> Once again, it's the amygdala in the limbic system 01:05:58.703 --> 01:06:02.120 that controls our emotional response. 01:06:02.120 --> 01:06:05.148 In this instance, it gets us psyched up to compete. 01:06:05.148 --> 01:06:06.955 01:06:06.955 --> 01:06:08.685 Back when the brain was evolving, 01:06:08.685 --> 01:06:11.303 it's how early man would get ready for the hunt. 01:06:11.303 --> 01:06:15.064 01:06:15.064 --> 01:06:18.056 But the amygdala needs to be triggered. 01:06:18.056 --> 01:06:20.542 One simple way is by using sensory stimulation 01:06:20.542 --> 01:06:22.821 such as cheering and clapping. 01:06:22.821 --> 01:06:25.719 01:06:25.719 --> 01:06:29.176 >> You can control it externally through loud noises, 01:06:29.176 --> 01:06:30.829 by slapping a person. 01:06:30.829 --> 01:06:31.529 Why? 01:06:31.529 --> 01:06:35.282 Because those sensory mechanisms go into the 01:06:35.282 --> 01:06:37.535 first floor of the brain. 01:06:37.535 --> 01:06:39.296 01:06:39.296 --> 01:06:42.157 So, you'll see in sports a lot of times people using 01:06:42.157 --> 01:06:44.602 this intuitively, a lot of noise - 01:06:44.602 --> 01:06:46.686 C'mon! C'mon! C'mon! Go! Go! Go! 01:06:46.686 --> 01:06:50.011 01:06:50.011 --> 01:06:51.880 Athletes need to get themselves into a position 01:06:51.880 --> 01:06:53.733 where when the game starts, 01:06:53.733 --> 01:06:56.989 they're at the right level of arousal because 01:06:56.989 --> 01:06:59.325 basketball is a contact sport. 01:07:00.140 --> 01:07:01.932 You gotta push out. 01:07:01.932 --> 01:07:05.248 You have to fight for the rebounds. 01:07:05.248 --> 01:07:07.443 01:07:07.443 --> 01:07:09.527 And it's almost this simulated war. 01:07:09.527 --> 01:07:18.852 01:07:18.852 --> 01:07:20.490 Once you're in a higher arousal level and you 01:07:20.490 --> 01:07:24.112 gotta come down, it's just as difficult as it is 01:07:24.112 --> 01:07:25.150 to go up. 01:07:25.150 --> 01:07:26.696 It might even be more difficult. 01:07:26.696 --> 01:07:28.334 01:07:28.334 --> 01:07:30.147 All of a sudden the game stops and they have to 01:07:30.147 --> 01:07:31.447 shoot a free throw. 01:07:31.447 --> 01:07:32.685 01:07:32.685 --> 01:07:34.431 >> The player needs to turn from pumped 01:07:34.431 --> 01:07:37.386 to quietly focused in seconds. 01:07:37.386 --> 01:07:39.859 Inside the player's brain the frontal lobes 01:07:39.859 --> 01:07:42.663 must quickly muffle the amygdala response 01:07:42.663 --> 01:07:47.010 to calm emotions, relax the body, breathe slower, 01:07:47.010 --> 01:07:49.510 and lower heart rate so that he stands a better 01:07:49.510 --> 01:07:52.111 chance at making the shot. 01:07:52.111 --> 01:07:54.392 This is tough because the player's body 01:07:54.392 --> 01:07:55.830 might be too pumped. 01:07:55.830 --> 01:07:58.302 01:07:58.302 --> 01:08:00.355 Or the frontal lobes might be distracted by 01:08:00.355 --> 01:08:03.254 other nervous thoughts like the fear of failure. 01:08:03.254 --> 01:08:04.276 01:08:04.276 --> 01:08:06.206 If these thoughts are strong enough, 01:08:06.206 --> 01:08:08.182 they could feed back to the limbic system 01:08:08.182 --> 01:08:10.970 and trigger the fear response. 01:08:10.970 --> 01:08:13.146 This would then make it extremely difficult to 01:08:13.146 --> 01:08:17.037 focus on performing a complicated action well. 01:08:17.037 --> 01:08:21.119 It's a situation experts call performance anxiety. 01:08:21.119 --> 01:08:27.782 01:08:27.782 --> 01:08:30.078 >> Performance anxiety is the largest culprit 01:08:30.078 --> 01:08:33.486 of poor athletic performance and the successful 01:08:33.486 --> 01:08:36.000 athlete has complete control over that. 01:08:36.000 --> 01:08:39.188 01:08:39.188 --> 01:08:41.041 >> It is tough to get your heart rate down 01:08:41.041 --> 01:08:42.756 and get focused 01:08:42.756 --> 01:08:44.944 and get concentrated on what you have to do 01:08:44.944 --> 01:08:46.367 because everything is so chaotic 01:08:46.367 --> 01:08:48.447 that all you want to do is go as fast as you can 01:08:48.447 --> 01:08:51.241 and you just need to relax and just try to stay cool. 01:08:51.241 --> 01:08:54.128 01:08:54.128 --> 01:08:56.239 >> Stay away from that white line, Graham. 01:08:56.239 --> 01:08:58.062 Stay way from that white line. 01:08:58.062 --> 01:08:58.684 01:08:58.684 --> 01:09:02.082 >> Get it wrong and the consequences can be fatal. 01:09:02.082 --> 01:09:03.843 01:09:03.843 --> 01:09:05.544 >> If you're concentration slips 01:09:05.544 --> 01:09:08.169 for any moment of time 01:09:08.169 --> 01:09:10.564 most often it would result in a crash. 01:09:10.564 --> 01:09:13.423 Top speeds can be up around 230 miles an hour 01:09:13.423 --> 01:09:15.230 and at those speeds anything can happen 01:09:15.230 --> 01:09:17.951 and when you hit the wall, you hit it hard. 01:09:17.951 --> 01:09:22.471 01:09:22.471 --> 01:09:24.944 >> Few sports demonstrate performance anxiety 01:09:24.944 --> 01:09:26.828 better than golf. 01:09:26.828 --> 01:09:29.347 >> People love golf because you'll see a 01:09:29.347 --> 01:09:33.296 world class athlete miss a two foot put to win a 01:09:33.296 --> 01:09:35.969 major tournament and lose hundreds of thousands 01:09:35.969 --> 01:09:37.407 of dollars. 01:09:37.407 --> 01:09:40.650 Putting requires a very low volume of activity. 01:09:40.650 --> 01:09:43.432 It's a small motor movement and the frontal lobes 01:09:43.432 --> 01:09:45.085 should probably be turned off. 01:09:45.085 --> 01:09:47.661 We know that Tiger Woods can do this because 01:09:47.661 --> 01:09:51.155 he's done it many times but what is it about his 01:09:51.155 --> 01:09:53.935 brain that he's able to put the ball into the hole? 01:09:53.935 --> 01:10:06.769 01:10:06.769 --> 01:10:09.052 What we found is that the brain can either 01:10:09.052 --> 01:10:11.889 help you succeed in this athletic activity 01:10:11.889 --> 01:10:13.989 or it can help you fail. 01:10:13.989 --> 01:10:16.110 01:10:16.110 --> 01:10:17.717 And we think Tiger Woods has found a way to 01:10:17.717 --> 01:10:21.147 succeed most of the time because of his ability 01:10:21.147 --> 01:10:23.814 to modulate his own brain functioning. 01:10:23.814 --> 01:10:25.912 >> Scientists can't scan Tiger Woods' brain 01:10:25.912 --> 01:10:27.012 in action. 01:10:27.012 --> 01:10:29.606 He would need to lie motionless which would 01:10:29.606 --> 01:10:31.982 make playing golf impossible. 01:10:32.519 --> 01:10:35.876 So instead, they must make an educated guess. 01:10:36.814 --> 01:10:39.949 >> Because he's blinking so little during a putt, 01:10:39.949 --> 01:10:43.440 we think that his anxiety is very low 01:10:43.440 --> 01:10:47.088 because eye blinking is usually related to anxiety. 01:10:47.088 --> 01:10:48.818 So he's very relaxed. 01:10:48.818 --> 01:10:52.259 Like a drowsy state, a drowsy sleepy level 01:10:52.259 --> 01:10:54.232 but yet enough concentration that you can 01:10:54.232 --> 01:10:55.608 focus on the task. 01:10:55.608 --> 01:11:01.698 01:11:01.698 --> 01:11:03.934 >> Athletes call this special feeling 01:11:03.934 --> 01:11:05.818 being in the zone 01:11:05.818 --> 01:11:07.840 when their movements seem to flow without 01:11:07.840 --> 01:11:09.309 conscious effort. 01:11:09.309 --> 01:11:10.270 01:11:10.270 --> 01:11:12.323 It is the supreme combination of practice 01:11:12.323 --> 01:11:14.253 involving the cerebellum, 01:11:14.253 --> 01:11:16.309 concentration in the frontal lobes, 01:11:16.309 --> 01:11:18.597 and low anxiety of the amygdala 01:11:18.597 --> 01:11:20.611 within the limbic system. 01:11:20.611 --> 01:11:22.705 >> Zone, it's very hard to get into. 01:11:22.705 --> 01:11:24.728 I really feel like if I can control my breath 01:11:24.728 --> 01:11:27.006 and I can get it as slow as possible, 01:11:27.006 --> 01:11:29.298 that will slow down my heart. 01:11:29.298 --> 01:11:31.744 As soon as that happens, I feel like I get total 01:11:31.744 --> 01:11:33.182 consciousness of everything. 01:11:33.182 --> 01:11:34.974 All five senses are working the best they can 01:11:34.974 --> 01:11:36.181 possibly work. 01:11:36.181 --> 01:11:37.111 01:11:37.111 --> 01:11:39.230 >> Experts think the brain gets so focused 01:11:39.230 --> 01:11:41.551 it's somehow able to block or ignore 01:11:41.551 --> 01:11:43.404 any irrelevant input. 01:11:43.988 --> 01:11:46.984 Brain and body begin working in perfect sync. 01:11:46.984 --> 01:11:49.904 >> Athletes and everybody else for that matter 01:11:49.904 --> 01:11:51.956 all want to be in that zone and there's something 01:11:51.956 --> 01:11:53.070 special about it. 01:11:53.070 --> 01:11:56.231 Everything gets aimed at the one task at hand 01:11:56.231 --> 01:11:59.211 and when you do that, incredible things can happen. 01:11:59.211 --> 01:12:02.835 You have real clarity of thought and decision making. 01:12:03.081 --> 01:12:05.358 >> When I'm in that moment, everything around 01:12:05.358 --> 01:12:07.196 me is slow and I can control what I'm thinking, 01:12:07.196 --> 01:12:08.511 I can control what I look at, 01:12:08.511 --> 01:12:11.071 I can control what thoughts enter my mind, 01:12:11.071 --> 01:12:13.859 and in turn that gives me the greatest chance 01:12:13.859 --> 01:12:15.066 for success. 01:12:15.066 --> 01:12:18.134 01:12:18.134 --> 01:12:19.957 >> Being in the zone could be the brain's 01:12:19.957 --> 01:12:22.456 ultimate control over the body. 01:12:22.456 --> 01:12:24.819 But there are some people who claim its 01:12:24.819 --> 01:12:27.217 ability extends even beyond that. 01:12:27.217 --> 01:12:28.840 01:12:28.840 --> 01:12:30.001 >> I am being pulled here. 01:12:30.308 --> 01:12:33.375 >> The notion that the brain has a sixth sense. 01:12:33.727 --> 01:12:35.364 >> He's also telling me to talk about - 01:12:36.348 --> 01:12:38.710 either Staten Island or - 01:12:38.710 --> 01:12:39.717 >> That's where we live. 01:12:39.717 --> 01:12:40.893 >> Okay, let me tell you exactly what he's showing 01:12:40.893 --> 01:12:42.300 me then so you know where. 01:12:42.300 --> 01:12:43.693 If you were to go over the bridge and through the 01:12:43.693 --> 01:12:45.658 toll and then take that first long road down the left - 01:12:45.658 --> 01:12:46.512 >> That's where I live. 01:12:46.512 --> 01:12:47.247 >> OK. 01:12:47.247 --> 01:12:49.693 01:12:49.693 --> 01:12:54.363 01:12:54.363 --> 01:12:57.256 >> Our five senses are the gateways between our 01:12:57.256 --> 01:13:00.340 brains and the outside world. 01:13:00.340 --> 01:13:04.129 We receive signals from our skin, eyes, nose, 01:13:04.129 --> 01:13:06.237 tongue, and ears. 01:13:06.237 --> 01:13:08.099 01:13:08.099 --> 01:13:10.350 The different areas of the brain interpret 01:13:10.350 --> 01:13:13.422 this sensory information as touch, sight, smell, 01:13:13.422 --> 01:13:15.168 taste and hearing. 01:13:15.168 --> 01:13:18.136 01:13:18.136 --> 01:13:21.777 But what if there were a sixth sense that enabled 01:13:21.777 --> 01:13:24.869 our brains to see into other people's minds, 01:13:24.869 --> 01:13:26.215 anticipate events 01:13:26.215 --> 01:13:28.566 or pass on messages from the dead? 01:13:28.566 --> 01:13:30.019 01:13:30.019 --> 01:13:32.150 Although one in four Americans say they believe 01:13:32.150 --> 01:13:34.387 in extrasensory perception, 01:13:34.387 --> 01:13:38.027 only a handful of scientists entertain this possibility. 01:13:39.436 --> 01:13:42.452 Dr. Dean Radin, researches psychic phenomena 01:13:42.452 --> 01:13:44.598 at the Institute of Noetic Sciences 01:13:44.598 --> 01:13:46.143 in northern California. 01:13:47.266 --> 01:13:50.064 His working theory is our brains might all have 01:13:50.064 --> 01:13:52.910 some extrasensory ability though we may call 01:13:52.910 --> 01:13:54.768 it something different. 01:13:54.768 --> 01:13:56.653 >> One thing that people commonly talk about is 01:13:56.653 --> 01:13:59.498 a gut feeling and a way it expresses itself 01:13:59.498 --> 01:14:01.342 often is while driving. 01:14:01.342 --> 01:14:03.895 They get a sense there's something wrong about 01:14:03.895 --> 01:14:05.810 this corner and more often than not, 01:14:05.810 --> 01:14:08.005 a car is coming from the other direction. 01:14:08.005 --> 01:14:11.196 So, I've learned to pay attention to my gut feelings. 01:14:11.196 --> 01:14:13.879 It's like pushing your attention a few seconds 01:14:13.879 --> 01:14:15.932 into the future. 01:14:15.932 --> 01:14:18.823 Other things are the feeling of being stared at 01:14:18.823 --> 01:14:22.442 which is very commonly reported effect 01:14:22.442 --> 01:14:25.377 typically by women feeling that a man somewhere 01:14:25.377 --> 01:14:26.753 is staring at them. 01:14:26.753 --> 01:14:29.448 There's also telephone telepathy without looking at 01:14:29.448 --> 01:14:32.236 your caller ID, sometimes people will hear the 01:14:32.236 --> 01:14:34.909 phone ring and immediately know who it is. 01:14:34.909 --> 01:14:37.574 And these are not cases where only one person 01:14:37.574 --> 01:14:40.636 ever calls but somebody unusual is calling. 01:14:40.636 --> 01:14:42.867 So, these are ways that these kinds of events 01:14:42.867 --> 01:14:46.062 appear in the every day world. 01:14:46.849 --> 01:14:48.672 >> Move your hand a little bit. 01:14:48.672 --> 01:14:51.796 Yes. Ooh, that's a very good signal. 01:14:51.796 --> 01:14:54.441 OK, I think we're ready to go! 01:14:54.441 --> 01:14:55.387 01:14:55.387 --> 01:14:58.494 >> Dr. Radin has tested more than 300 volunteers 01:14:58.494 --> 01:15:00.938 in electromagnetically shielded rooms. 01:15:00.938 --> 01:15:02.838 01:15:02.838 --> 01:15:04.933 He shows them a series of images and 01:15:04.933 --> 01:15:06.786 measures their reactions. 01:15:06.786 --> 01:15:09.501 We were sent in a random sequence, 01:15:09.501 --> 01:15:12.122 pictures which are calm or emotional. 01:15:12.122 --> 01:15:13.806 And also pictures in between. 01:15:14.606 --> 01:15:16.352 The more emotional pictures 01:15:16.352 --> 01:15:18.544 evoke a stronger response. 01:15:18.544 --> 01:15:20.930 01:15:20.930 --> 01:15:22.937 What Dr. Radin found is that 01:15:22.937 --> 01:15:25.563 while his pool of subjects is randomly chosen, 01:15:25.563 --> 01:15:27.555 he always finds people who respond 01:15:27.555 --> 01:15:30.254 accurately before they see the image. 01:15:31.069 --> 01:15:33.813 They seem to know ahead of time the kind of picture 01:15:33.813 --> 01:15:34.990 they'll see. 01:15:34.990 --> 01:15:36.182 01:15:36.182 --> 01:15:38.020 Though their degree of psychic ability appears 01:15:38.020 --> 01:15:39.120 to vary. 01:15:39.120 --> 01:15:40.081 01:15:40.081 --> 01:15:41.811 >> Not everybody is going to be able to play golf 01:15:41.811 --> 01:15:43.904 as good as Tiger Woods 01:15:43.904 --> 01:15:46.709 but everybody can play golf a little bit. 01:15:46.709 --> 01:15:48.455 So, what we tend to see in the laboratory 01:15:48.455 --> 01:15:50.627 is everybody playing golf a little bit. 01:15:50.627 --> 01:15:52.542 And occasionally we are lucky and we get 01:15:52.542 --> 01:15:54.411 the equivalent of Tiger Woods. 01:15:54.411 --> 01:15:56.264 >> Somebody is claiming they were buried with gum. 01:15:56.264 --> 01:15:59.061 01:15:59.061 --> 01:16:00.961 Somebody was buried with gum. 01:16:00.961 --> 01:16:02.890 You buried somebody with chewing gum? 01:16:02.890 --> 01:16:04.325 Take the mic, please. 01:16:04.881 --> 01:16:07.559 >> John Edwards' success as a TV medium 01:16:07.559 --> 01:16:11.231 would suggest he's in the Tiger Woods category. 01:16:11.231 --> 01:16:14.897 >> In the history of science, we've often been wrong. 01:16:14.897 --> 01:16:16.366 We used to think the earth was flat. 01:16:16.366 --> 01:16:17.450 We were wrong. 01:16:17.450 --> 01:16:19.350 We used to think the sun revolved around the earth. 01:16:19.350 --> 01:16:20.496 We were wrong. 01:16:21.172 --> 01:16:24.243 We used to think physical objects were solid 01:16:24.243 --> 01:16:25.589 and static. 01:16:25.589 --> 01:16:27.492 We now know that was wrong. 01:16:28.560 --> 01:16:31.806 So, I start from a point of view when anybody 01:16:31.806 --> 01:16:34.738 makes a claim whether it's a medium or a healer 01:16:34.738 --> 01:16:37.415 I approach it as I don't know. 01:16:37.415 --> 01:16:38.345 Could be yes. 01:16:38.345 --> 01:16:39.629 Could be no. 01:16:39.629 --> 01:16:40.959 Show me the data. 01:16:40.959 --> 01:16:42.059 I'm open. 01:16:42.059 --> 01:16:43.497 >> You only put a couple of sticks in? 01:16:43.497 --> 01:16:47.516 >> His old secretary, they used to chew 01:16:47.516 --> 01:16:50.419 the same gum and we put it in the casket with him. 01:16:50.419 --> 01:16:51.472 >> A couple of sticks? 01:16:51.472 --> 01:16:55.126 >> It was, I think they're like individual packet, 01:16:55.126 --> 01:16:57.504 like um, like the Bazooka, 01:16:57.504 --> 01:16:58.895 the one with the comics. 01:16:58.895 --> 01:16:59.934 >> OK, so that's why I'm feeling. 01:16:59.934 --> 01:17:00.772 >> They're individual. 01:17:00.772 --> 01:17:02.348 >> Right. Would this be like a father figure to you? 01:17:02.348 --> 01:17:03.293 >> It's my dad. 01:17:03.293 --> 01:17:04.108 >> OK. 01:17:04.478 --> 01:17:06.131 And do you still see his assistant? 01:17:06.131 --> 01:17:07.123 >> Yes. 01:17:08.399 --> 01:17:09.929 >> He wants you to tease her, like what she 01:17:09.929 --> 01:17:11.629 couldn't spare a few more slices or what? 01:17:12.321 --> 01:17:14.282 Like I couldn't have the whole pack? 01:17:14.282 --> 01:17:15.935 [Audience laughing] 01:17:15.935 --> 01:17:19.278 >> The way the process of mediumship typically 01:17:19.278 --> 01:17:23.769 operates is that the mediums get little pieces 01:17:23.769 --> 01:17:24.761 of information. 01:17:24.761 --> 01:17:25.999 >> Because he's making me feel like, 01:17:25.999 --> 01:17:27.329 wasn't he already kind of gone? 01:17:27.329 --> 01:17:28.490 >> Yes, he was. 01:17:28.490 --> 01:17:31.322 >> Not because the other side is fragmented 01:17:31.322 --> 01:17:33.838 but because they're just able to pick up little 01:17:33.838 --> 01:17:34.615 snippets. 01:17:34.615 --> 01:17:36.873 It's like you've got a semi-good connection 01:17:36.873 --> 01:17:38.557 on your cellphone and get a piece of information 01:17:38.557 --> 01:17:40.533 here and a piece of information there. 01:17:40.533 --> 01:17:42.487 >> People say well, where are they and how do you 01:17:42.487 --> 01:17:43.432 do this? 01:17:43.432 --> 01:17:44.808 It's like, well where's the Internet? 01:17:44.808 --> 01:17:46.897 It's a place that exists but you can't go there 01:17:46.897 --> 01:17:48.258 with a physical body. 01:17:48.258 --> 01:17:49.727 You have to have a conduit of some sort, 01:17:49.727 --> 01:17:52.031 some sort of connection to get to it. 01:17:52.031 --> 01:17:53.607 You've got to be plugged in somehow. 01:17:53.607 --> 01:17:55.799 >> Anybody have a plastic frog with them? 01:17:55.799 --> 01:17:57.883 I'm being pulled here. 01:17:57.883 --> 01:17:59.813 So like from here over, you guys are safe. 01:17:59.813 --> 01:18:02.191 Over here - no. 01:18:02.191 --> 01:18:04.707 When I've doing an event I will get a pull 01:18:04.707 --> 01:18:06.637 to the section of the room or specific area 01:18:06.637 --> 01:18:07.890 of the people. 01:18:07.890 --> 01:18:10.591 >> My nephew asked for Christmas a toy frog 01:18:10.591 --> 01:18:14.096 and it was his dad who passed away. 01:18:14.096 --> 01:18:16.141 >> And his dad passed before Christmas? 01:18:16.141 --> 01:18:17.441 >> Yes. 01:18:17.441 --> 01:18:20.198 >> When I'm hearing something I don't hear it in my ear. 01:18:20.198 --> 01:18:22.294 I fell like I'm hearing it outside of me but 01:18:22.294 --> 01:18:23.732 it's a thought that I'm hearing. 01:18:24.393 --> 01:18:26.976 >> John is one of several psychic mediums who 01:18:26.976 --> 01:18:29.283 agreed to undergo scientific testing 01:18:29.283 --> 01:18:31.479 at the University of Arizona. 01:18:31.758 --> 01:18:33.304 >> We're going to put a cap on you 01:18:33.304 --> 01:18:35.542 that has 19 electrodes. 01:18:35.542 --> 01:18:39.017 >> I did three experiments with John Edwards. 01:18:39.017 --> 01:18:42.812 Each one more controlled than the next. 01:18:42.812 --> 01:18:44.773 The most controlled of them involved fitting 01:18:44.773 --> 01:18:47.763 the mediums and the volunteers with EEGs 01:18:47.763 --> 01:18:51.222 on their heads and EKGs on their chests. 01:18:51.222 --> 01:18:53.075 One of the ways to address the question, 01:18:53.075 --> 01:18:56.307 is the medium reading the mind of the sitter 01:18:56.307 --> 01:18:59.381 versus reading the mind of the deceased 01:18:59.381 --> 01:19:03.504 is to record the brainwave activity and the 01:19:03.504 --> 01:19:06.242 cardiac activity, the heart and brain, 01:19:06.242 --> 01:19:08.822 of the medium and simultaneously record 01:19:08.822 --> 01:19:11.419 the brain and the heart of the sitter. 01:19:11.419 --> 01:19:13.925 01:19:13.925 --> 01:19:15.501 >> The medium never meets the subject 01:19:15.501 --> 01:19:18.298 and they sit separated by a screen. 01:19:18.298 --> 01:19:20.571 John and the other mediums have to get 01:19:20.571 --> 01:19:22.163 whatever information they can 01:19:22.163 --> 01:19:24.662 about the subject's deceased loved ones. 01:19:24.662 --> 01:19:25.576 01:19:25.576 --> 01:19:27.075 >> I'm going to tell you what I'm seeing, hearing, 01:19:27.075 --> 01:19:29.219 and feeling and basically ask you to confirm 01:19:29.219 --> 01:19:31.318 and verify simply by yes's and no's. 01:19:31.318 --> 01:19:31.741 >> OK. 01:19:31.741 --> 01:19:33.410 >> OK, the first thing that's coming through is 01:19:33.410 --> 01:19:34.479 they're telling me to talk to you about a male 01:19:34.479 --> 01:19:35.409 figure to your side. 01:19:35.409 --> 01:19:36.662 A male figure to your side would be 01:19:36.662 --> 01:19:38.285 a husband or a brother who has crossed over. 01:19:38.285 --> 01:19:39.154 Do you understand that? 01:19:39.154 --> 01:19:39.930 >> Yes. 01:19:39.930 --> 01:19:41.091 >> OK, actually there's two. 01:19:41.091 --> 01:19:42.006 There's three. 01:19:42.006 --> 01:19:43.598 There were a couple occasions that I sat 01:19:43.598 --> 01:19:45.421 with people and got nothing. 01:19:45.421 --> 01:19:47.929 You know, and like I got absolutely nothing. 01:19:47.929 --> 01:19:49.490 So, and they'd be like why is that happening? 01:19:49.490 --> 01:19:51.251 I'm like, I don't know. 01:19:51.251 --> 01:19:52.566 I'm like maybe it's me. 01:19:52.566 --> 01:19:53.589 I don't know. 01:19:53.589 --> 01:19:55.135 So I got zeroes for that. 01:19:55.135 --> 01:19:58.934 >> But sometimes John will get accurate information, 01:19:58.934 --> 01:20:02.062 the sitter will either think he's wrong and later 01:20:02.062 --> 01:20:05.395 discover he's correct, or the sitter won't know the 01:20:05.395 --> 01:20:07.664 answer and they'll have to then contact some 01:20:07.664 --> 01:20:09.533 of the family members and friends 01:20:09.533 --> 01:20:12.074 and low and behold discover that it was correct. 01:20:12.074 --> 01:20:14.375 And we found that in that experiment as well. 01:20:14.375 --> 01:20:16.246 01:20:16.246 --> 01:20:18.192 >> John's accuracy rate typically averaged 01:20:18.192 --> 01:20:20.136 80-90%. 01:20:21.705 --> 01:20:23.712 And the monitoring machinery showed his 01:20:23.712 --> 01:20:26.247 brainwaves and heart rate were not mimicking 01:20:26.247 --> 01:20:27.362 the subject's. 01:20:27.362 --> 01:20:29.031 01:20:29.031 --> 01:20:32.185 >> We discovered that John's heart actually went out 01:20:32.185 --> 01:20:36.737 of sync with the sitter which implied, of course 01:20:36.737 --> 01:20:39.282 that his attention was somewhere else. 01:20:39.282 --> 01:20:40.428 >> They're also telling me to talk about the dog 01:20:40.428 --> 01:20:41.958 that's named after a drink. 01:20:41.958 --> 01:20:43.058 So, I don't know if there's like a - 01:20:43.058 --> 01:20:44.173 >> My dog Jager. 01:20:44.173 --> 01:20:44.657 >> Jager? 01:20:44.657 --> 01:20:45.695 >> Yes! 01:20:45.695 --> 01:20:47.916 01:20:47.916 --> 01:20:49.539 >> By the way, apparently he needs a bath. 01:20:49.539 --> 01:20:52.308 >> Yes, he smells right now, he does. 01:20:52.308 --> 01:20:55.924 >> Based on the laboratory experiments 01:20:55.924 --> 01:20:58.531 that I've done with John, 01:20:58.531 --> 01:21:03.368 I am clearly led to the conclusion 01:21:03.368 --> 01:21:06.931 that John is a real medium. 01:21:06.931 --> 01:21:07.646 01:21:07.646 --> 01:21:09.860 >> The so-called Afterlife Experiments 01:21:09.860 --> 01:21:12.016 remain highly controversial within 01:21:12.016 --> 01:21:13.608 the scientific community 01:21:13.608 --> 01:21:15.952 in part, because they raise more questions 01:21:15.952 --> 01:21:17.790 than they answer. 01:21:17.790 --> 01:21:21.111 >> At the present time, scientifically, we don't 01:21:21.111 --> 01:21:24.596 know how real mediums like John Edwards 01:21:24.596 --> 01:21:26.909 do what they do. 01:21:26.909 --> 01:21:29.575 The working hypothesis that we entertain 01:21:29.575 --> 01:21:32.449 in our laboratory is that we all have energy. 01:21:32.449 --> 01:21:36.117 This energy continues like the light from 01:21:36.117 --> 01:21:37.278 distant stars. 01:21:37.278 --> 01:21:39.116 And what John does and others do 01:21:39.116 --> 01:21:41.149 is that their brains and consciousness 01:21:41.149 --> 01:21:43.317 serve as an antenna and receiver 01:21:43.332 --> 01:21:45.809 and what they do is they learn how to tune 01:21:45.809 --> 01:21:48.230 into the signals that are present and keep 01:21:48.230 --> 01:21:53.072 their noise low and then receive these subtle signals. 01:21:53.072 --> 01:21:57.165 >> The concept of a connected fabric of reality 01:21:57.165 --> 01:21:59.249 of which we are part of that, 01:21:59.249 --> 01:22:00.241 by virtue of being here, 01:22:00.241 --> 01:22:03.532 is similar to something like The Force from Star Wars. 01:22:05.438 --> 01:22:08.834 Obi-Wan at some point suddenly feels a disturbance 01:22:08.834 --> 01:22:11.263 in The Force when a planet is blown up. 01:22:11.263 --> 01:22:13.803 01:22:13.803 --> 01:22:16.988 And in a sense he's feeling ripples through this 01:22:16.988 --> 01:22:20.411 space time medium that he's able to sense directly. 01:22:21.933 --> 01:22:24.720 The phenomena that we call ESP, 01:22:24.720 --> 01:22:28.125 probably operate on something like that. 01:22:28.125 --> 01:22:29.638 >> Physics has a name for this 01:22:29.638 --> 01:22:31.089 distant connectedness, 01:22:31.089 --> 01:22:33.959 it's called the quantum entanglement. 01:22:33.959 --> 01:22:36.215 At the moment it's just a theory being applied 01:22:36.215 --> 01:22:38.819 to electrons and molecules. 01:22:38.819 --> 01:22:42.026 Scientists don't know yet if it could apply to the brain. 01:22:42.026 --> 01:22:43.234 01:22:43.234 --> 01:22:45.134 But the breakthrough that confirms 01:22:45.134 --> 01:22:47.516 extra sensory perception could come sooner 01:22:47.516 --> 01:22:49.339 than we think. 01:22:49.339 --> 01:22:50.639 01:22:50.639 --> 01:22:52.754 >> It's always very difficult predict. 01:22:52.754 --> 01:22:54.438 when such things happen. 01:22:54.438 --> 01:22:56.495 01:22:56.495 --> 01:22:59.105 I would guess maybe 20 years. 01:22:59.105 --> 01:23:04.196 Sometime between tomorrow and 20 years. 01:23:04.196 --> 01:23:06.713 >> The next two decades promise to unlock many 01:23:06.713 --> 01:23:09.208 mysteries about the brain. 01:23:09.208 --> 01:23:11.563 Neuroscientists are already working on smart 01:23:11.563 --> 01:23:13.803 technologies that could change our lives 01:23:13.803 --> 01:23:15.964 in ways we'd never imagine. 01:23:15.964 --> 01:23:18.247 01:23:18.247 --> 01:23:20.300 >> We will get to a point, I believe, 01:23:20.300 --> 01:23:23.463 when there will be instantaneous communication 01:23:23.463 --> 01:23:25.547 from the web to our brains. 01:23:25.547 --> 01:23:26.662 That I'm sure. 01:23:26.662 --> 01:23:31.146 01:23:31.146 --> 01:23:34.081 >> What if we could supercharge our brains using 01:23:34.081 --> 01:23:36.728 machines and take the next leap of evolution 01:23:36.728 --> 01:23:38.612 within a single lifetime 01:23:38.612 --> 01:23:41.155 instead of over many lifetimes? 01:23:41.155 --> 01:23:42.808 01:23:42.808 --> 01:23:45.155 Radical innovation is the goal of programs 01:23:45.155 --> 01:23:47.901 being funded by the semi-secret DARPA, 01:23:47.901 --> 01:23:51.306 The Defense Advanced Research Projects Agency. 01:23:51.306 --> 01:23:53.348 01:23:53.348 --> 01:23:56.935 Their mission is to be kind of the blue sky thinkers 01:23:56.935 --> 01:24:01.167 of science for the National Security Establishment. 01:24:01.167 --> 01:24:03.891 And they've produced some amazing technologies 01:24:03.891 --> 01:24:05.221 that we take for granted. 01:24:05.221 --> 01:24:06.874 Besides the Internet, the computer mouse, 01:24:06.874 --> 01:24:08.758 and of course the Stealth Bomber. 01:24:08.758 --> 01:24:10.811 01:24:10.811 --> 01:24:12.480 They take some of the smartest scientists 01:24:12.480 --> 01:24:16.040 in the country and they ask them to push 01:24:16.040 --> 01:24:19.071 current science 30, 40 years into the future. 01:24:19.071 --> 01:24:20.463 To take big leaps. 01:24:21.708 --> 01:24:23.768 >> DARPA is funding one such leap 01:24:23.768 --> 01:24:26.195 at Columbia University in New York. 01:24:26.195 --> 01:24:27.371 01:24:27.371 --> 01:24:30.130 Scientists there are developing a computer program 01:24:30.130 --> 01:24:32.699 that helps the brain process visual information 01:24:32.699 --> 01:24:35.223 at lightning speed. 01:24:35.223 --> 01:24:36.989 >> In our modern society 01:24:36.989 --> 01:24:38.859 we are bombarded with information. 01:24:38.859 --> 01:24:41.303 Whether it's images from television, 01:24:41.303 --> 01:24:43.018 images on the web, 01:24:43.018 --> 01:24:46.204 from one's job and it's starting to be overwhelming. 01:24:46.204 --> 01:24:48.435 And we need to figure which images we really 01:24:48.435 --> 01:24:49.765 need to spend time looking at 01:24:49.765 --> 01:24:51.864 and which we can ignore. 01:24:51.864 --> 01:24:54.878 The idea behind Cortically-Coupled Computer Vision 01:24:54.878 --> 01:24:57.267 is to create the best of both worlds. 01:24:57.267 --> 01:24:59.482 The versatility of the human brain 01:24:59.482 --> 01:25:02.343 enhanced by the speed of computer. 01:25:02.343 --> 01:25:02.919 01:25:02.919 --> 01:25:05.382 >> It's very hard to tell a computer vision system, 01:25:05.382 --> 01:25:08.029 find something that's funny or out of the ordinary 01:25:08.029 --> 01:25:09.159 or suspicious. 01:25:09.159 --> 01:25:11.783 It's much easier to have a person do that. 01:25:11.783 --> 01:25:14.097 Of course, computer vision systems are very fast 01:25:14.097 --> 01:25:16.287 so the question is, how can we actually make the 01:25:16.303 --> 01:25:18.971 human visual processor faster? 01:25:18.971 --> 01:25:21.674 >> In this example, the images are aerial shots 01:25:21.674 --> 01:25:23.650 of Seoul in South Korea. 01:25:24.957 --> 01:25:26.903 The analyst is looking for helipads. 01:25:26.903 --> 01:25:29.704 01:25:29.704 --> 01:25:32.448 The old slow method would require a methodical 01:25:32.448 --> 01:25:34.849 search of thousands of individual photos 01:25:34.849 --> 01:25:36.949 before marking each helipad. 01:25:36.949 --> 01:25:38.172 01:25:38.172 --> 01:25:40.364 The new method involves the analyst wearing 01:25:40.364 --> 01:25:42.016 an EEG cap. 01:25:43.246 --> 01:25:45.826 Dozens of electrodes can now detect electrical 01:25:45.826 --> 01:25:49.834 brain activity just below the surface of the skull. 01:25:49.834 --> 01:25:52.460 In normal brain processing, the visual cortex 01:25:52.460 --> 01:25:54.818 extracts detail from a scene. 01:25:54.818 --> 01:25:57.622 Information is sent forward to the frontal lobes 01:25:57.622 --> 01:25:59.649 for decision making. 01:25:59.649 --> 01:26:02.072 Then the motor cortex generates a response; 01:26:02.072 --> 01:26:05.372 the click of a mouse or the movement of the eyes. 01:26:06.079 --> 01:26:08.566 The prototype program intercepts the signals, 01:26:08.566 --> 01:26:11.563 filters out irrelevant brain activity, 01:26:11.563 --> 01:26:14.828 and focuses on the subliminal "aha" moment 01:26:14.828 --> 01:26:17.486 when the eyes spot a helipad. 01:26:17.486 --> 01:26:20.548 In just a few seconds, the analyst can sift through 01:26:20.548 --> 01:26:22.755 the thousands of images. 01:26:22.755 --> 01:26:25.545 Although he may not be consciously aware of it, 01:26:25.545 --> 01:26:28.482 his brain is remarkably accurate at identifying 01:26:28.482 --> 01:26:30.873 the few shots that have helipads in them 01:26:30.873 --> 01:26:32.865 so they can be marked up later. 01:26:32.865 --> 01:26:33.779 01:26:33.779 --> 01:26:36.210 So essentially we're going to tap into the signals 01:26:36.210 --> 01:26:39.563 that are involved in deciding whether there is 01:26:39.563 --> 01:26:42.279 something interesting and without having the subject 01:26:42.279 --> 01:26:46.050 having to make a response, use that to now reorder 01:26:46.050 --> 01:26:49.060 or resort image databases to improve search. 01:26:49.060 --> 01:26:53.975 01:26:53.975 --> 01:26:56.047 >> This boosted vision technology helps the 01:26:56.047 --> 01:26:58.928 image analyst work up to four times faster. 01:26:58.928 --> 01:27:01.055 01:27:01.055 --> 01:27:03.311 It could be adapted to help fighter pilots 01:27:03.311 --> 01:27:05.861 make better split second decisions 01:27:05.861 --> 01:27:08.167 or to improve the sifting of surveillance footage 01:27:08.167 --> 01:27:10.647 by police or security personnel. 01:27:10.647 --> 01:27:13.543 01:27:13.543 --> 01:27:15.612 And then there are possibilities beyond 01:27:15.612 --> 01:27:17.527 defense and intelligence. 01:27:17.527 --> 01:27:18.103 01:27:18.103 --> 01:27:20.099 >> One potential application that is of interest 01:27:20.099 --> 01:27:22.229 in which there's high-throughput of information 01:27:22.229 --> 01:27:24.928 might been in the stock market or in trading. 01:27:24.928 --> 01:27:28.160 Many times traders are assimilating this information 01:27:28.160 --> 01:27:29.890 across different screens, 01:27:29.890 --> 01:27:32.094 something might catch their eye but they can't 01:27:32.094 --> 01:27:34.259 actually act on that at that moment. 01:27:34.259 --> 01:27:36.938 So that information can be tagged that it grabbed 01:27:36.938 --> 01:27:39.435 the interest of the trader and processed by 01:27:39.435 --> 01:27:41.821 some other person down the line. 01:27:41.821 --> 01:27:42.613 01:27:42.613 --> 01:27:44.574 >> Medical research might be interested in these 01:27:44.574 --> 01:27:46.166 devices, too. 01:27:46.166 --> 01:27:48.230 And marketing teams could use them to record 01:27:48.230 --> 01:27:50.037 people's first reaction to a product 01:27:50.037 --> 01:27:52.198 or advertising campaign. 01:27:52.198 --> 01:27:54.589 A video game company in California 01:27:54.589 --> 01:27:57.166 is already ditching the joy stick in favor of 01:27:57.166 --> 01:27:58.958 brain power. 01:27:58.958 --> 01:28:01.611 A headset similar to an EEG picks up 01:28:01.611 --> 01:28:04.179 electrical activity from the brain as well as 01:28:04.179 --> 01:28:07.001 twitches from facial muscles. 01:28:07.001 --> 01:28:08.870 The signals get translated into onscreen 01:28:08.870 --> 01:28:10.354 commands. 01:28:10.354 --> 01:28:11.915 01:28:11.915 --> 01:28:14.392 Players raise rocks and vanquish villains 01:28:14.392 --> 01:28:16.844 not with a click but with a thought. 01:28:16.844 --> 01:28:20.325 01:28:20.325 --> 01:28:22.409 The future potential for implanted 01:28:22.409 --> 01:28:24.746 Personal Data Assistance or PDAs 01:28:24.746 --> 01:28:27.176 is almost mind-boggling. 01:28:28.145 --> 01:28:29.931 >> As we get older, we all worry about our 01:28:29.931 --> 01:28:31.969 inability to remember names and faces. 01:28:31.969 --> 01:28:34.088 We're going to find ways to compensate for that 01:28:34.088 --> 01:28:37.380 loss of natural evolved memory revolving in the 01:28:37.380 --> 01:28:38.941 direction where we will have devices 01:28:38.941 --> 01:28:40.625 that will do that for us. 01:28:40.625 --> 01:28:42.140 And I think ultimately we will have a Facebook 01:28:42.140 --> 01:28:43.347 in our heads. 01:28:43.347 --> 01:28:45.948 At that point, it's going to be pretty hard 01:28:45.948 --> 01:28:49.827 to see where we end and the technology begins. 01:28:49.827 --> 01:28:51.663 01:28:51.663 --> 01:28:53.839 At Duke University in North Carolina, 01:28:53.839 --> 01:28:57.668 neuroscientists are taking that next step already. 01:28:57.668 --> 01:29:00.257 They've implanted electrodes into a monkey's brain 01:29:00.257 --> 01:29:03.375 and isolated the brain signals for walking. 01:29:03.375 --> 01:29:04.998 01:29:04.998 --> 01:29:06.867 During one recent experiment, 01:29:06.867 --> 01:29:09.129 a monkey paced on a treadmill while her brain 01:29:09.129 --> 01:29:11.999 activity was sent via the Internet to Japan 01:29:11.999 --> 01:29:14.484 to instantly control the walking of a five foot 01:29:14.484 --> 01:29:16.276 humanoid robot. 01:29:16.276 --> 01:29:17.986 01:29:17.986 --> 01:29:19.762 The monkey got raisin treats for making 01:29:19.762 --> 01:29:21.646 the robot walk. 01:29:21.646 --> 01:29:24.461 Then her treadmill was switched off. 01:29:24.461 --> 01:29:24.975 01:29:24.975 --> 01:29:27.397 In her desire for more treats, 01:29:27.397 --> 01:29:29.497 the monkey kept the robot walking 01:29:29.497 --> 01:29:32.531 using only her thoughts. 01:29:32.531 --> 01:29:34.200 And there's been a similar breakthrough 01:29:34.200 --> 01:29:37.068 at the University of Pittsburgh in Pennsylvania. 01:29:37.641 --> 01:29:40.558 Monkeys fitted with tiny sensors in their brains 01:29:40.558 --> 01:29:42.853 have learned to control a mechanical arm 01:29:42.853 --> 01:29:45.169 and use it to reach for snacks. 01:29:45.169 --> 01:29:45.868 01:29:45.868 --> 01:29:48.013 It will have tremendous applications for medicine, 01:29:48.013 --> 01:29:49.959 for people who are amputees, 01:29:49.959 --> 01:29:51.935 for people who are quadriplegic; 01:29:51.935 --> 01:29:54.314 giving them the ability to move a robot 01:29:54.314 --> 01:29:57.273 prosthetic arms and legs in ways that will allow 01:29:57.273 --> 01:29:59.188 them to interact with their environments 01:29:59.188 --> 01:30:02.073 which they have not been able to do before. 01:30:02.073 --> 01:30:04.173 >> Could there be hope in the future for someone 01:30:04.173 --> 01:30:07.012 like Clive Waring whose brain damage means 01:30:07.012 --> 01:30:09.127 he can't process new memories? 01:30:09.127 --> 01:30:10.980 >> I don't remember sitting down on this seat. 01:30:10.980 --> 01:30:12.371 That was unknown to me. 01:30:12.371 --> 01:30:12.547 01:30:12.547 --> 01:30:15.035 >> There's work being done currently with rats 01:30:15.035 --> 01:30:16.965 that might one day create a synthetic 01:30:16.965 --> 01:30:19.191 hippocampus for humans. 01:30:19.191 --> 01:30:20.798 >> If you could do that in theory, 01:30:20.798 --> 01:30:23.655 you could actually introduce instantaneously 01:30:23.655 --> 01:30:26.743 new memories as we do in computer chips 01:30:26.743 --> 01:30:28.289 every day these days. 01:30:28.289 --> 01:30:30.578 But what if instead of taking months and months 01:30:30.578 --> 01:30:32.170 to learn a language we could download 01:30:32.170 --> 01:30:34.485 a basic dictionary of a language? 01:30:34.485 --> 01:30:36.308 Or what if having never been somewhere 01:30:36.308 --> 01:30:39.106 instead of having to carry that tour guide 01:30:39.106 --> 01:30:41.067 or book around, that clumsy book, 01:30:41.067 --> 01:30:42.259 and stopping in the middle of the sidewalk 01:30:42.259 --> 01:30:43.543 every few minutes to see where we were going, 01:30:43.543 --> 01:30:46.566 we actually had a rudimentary map that had been 01:30:46.566 --> 01:30:49.270 downloaded into our brains of that new city 01:30:49.270 --> 01:30:50.877 that we're visiting or those monuments 01:30:50.877 --> 01:30:51.977 that we're looking at? 01:30:51.977 --> 01:30:54.981 01:30:54.981 --> 01:30:57.417 >> Drugs are being developed for combat troops 01:30:57.417 --> 01:30:59.024 that would allow them to stay awake 01:30:59.024 --> 01:31:01.738 for two or three days with no ill effects. 01:31:01.738 --> 01:31:02.653 01:31:02.653 --> 01:31:04.905 A new class of chemicals called ampakines, 01:31:04.905 --> 01:31:07.453 are thought to help the neurotransmitter glutamate 01:31:07.453 --> 01:31:09.568 work better in a tired brain 01:31:09.568 --> 01:31:13.184 and so improve memory, learning, and cognition. 01:31:13.184 --> 01:31:14.591 01:31:14.591 --> 01:31:16.640 These could eventually find their way into 01:31:16.640 --> 01:31:18.537 everyday use. 01:31:18.537 --> 01:31:20.452 >> Lack of sleep historically has meant that you are 01:31:20.452 --> 01:31:22.105 inclined to make mistakes. 01:31:22.105 --> 01:31:23.528 I think we're going to be able to resolve 01:31:23.528 --> 01:31:24.335 that problem. 01:31:24.335 --> 01:31:26.250 Shift workers, people that have to work all night 01:31:26.250 --> 01:31:28.401 might be able to do without sleep and function 01:31:28.401 --> 01:31:29.362 very well. 01:31:29.362 --> 01:31:32.322 Students who are studying for exams, 01:31:32.322 --> 01:31:34.579 people who have to travel across time zones 01:31:34.579 --> 01:31:35.987 as part of their work. 01:31:35.987 --> 01:31:37.410 01:31:37.410 --> 01:31:40.238 >> In the near future, scientists expect to perfect 01:31:40.238 --> 01:31:42.414 portable brain scanners. 01:31:42.414 --> 01:31:45.180 Light-emitting diodes fitted in a headband 01:31:45.180 --> 01:31:47.627 would bounce light into the frontal lobes 01:31:47.627 --> 01:31:49.727 to detect brain activity. 01:31:49.727 --> 01:31:50.488 01:31:50.488 --> 01:31:52.234 That information would be fed into a unit 01:31:52.234 --> 01:31:55.263 no bigger than a pack of playing cards. 01:31:55.263 --> 01:31:58.832 Instead of lying motionless in a giant MRI machine, 01:31:58.832 --> 01:32:01.395 wearers could discover what's going on in their 01:32:01.395 --> 01:32:04.119 brains while, for example, playing sports. 01:32:04.119 --> 01:32:08.178 01:32:08.178 --> 01:32:10.355 >> We will be able to look into a super athlete's 01:32:10.355 --> 01:32:14.060 brain like Federeror or Agasi or Tiger Woods 01:32:14.060 --> 01:32:17.122 and see not that they're different anatomically 01:32:17.122 --> 01:32:20.106 necessarily, but functionally they are different 01:32:20.106 --> 01:32:22.481 in terms of how they process information. 01:32:22.481 --> 01:32:24.842 The second application is that you can use this 01:32:24.842 --> 01:32:27.936 new technology to help athletes perform better 01:32:27.936 --> 01:32:29.940 or perform up to their capacity. 01:32:29.940 --> 01:32:32.908 >> Imaging technology is still in its infancy. 01:32:32.908 --> 01:32:35.651 In widespread use for less than 20 years, 01:32:35.651 --> 01:32:38.523 compared with over 100 years for X-rays, 01:32:38.523 --> 01:32:41.389 it's limited only by our imagination. NOTE Paragraph 01:32:41.389 --> 01:32:42.827 >> The pictures that we get of the brain right now 01:32:42.827 --> 01:32:44.803 though there are several amazing technologies 01:32:44.803 --> 01:32:47.194 are pretty gross, they're at a large level. 01:32:47.194 --> 01:32:49.240 Now people are saying, wow it would be really 01:32:49.240 --> 01:32:51.446 good if we could get a more granular, 01:32:51.446 --> 01:32:54.800 more fine grained deeper images of the brain, 01:32:54.800 --> 01:32:56.730 at the molecular level and I think that's the 01:32:56.730 --> 01:32:59.022 next frontier for brain imaging. 01:32:59.022 --> 01:33:01.820 >> For all that we have learned about the brain, 01:33:01.820 --> 01:33:04.865 we still have so much to discover. 01:33:04.865 --> 01:33:06.749 >> There are many unsolved questions that remain 01:33:06.749 --> 01:33:09.033 about the brain and they're surprisingly 01:33:09.033 --> 01:33:11.961 simple; how is memory actually stored and 01:33:11.961 --> 01:33:13.645 how does it get reconstructed? 01:33:13.645 --> 01:33:15.514 Why do brains sleep and dream? 01:33:15.514 --> 01:33:17.275 What is intelligence? 01:33:17.275 --> 01:33:19.375 Why do people have a variety of skills 01:33:19.375 --> 01:33:20.521 and talents? 01:33:20.521 --> 01:33:21.897 How do we perceive the world? 01:33:21.897 --> 01:33:23.458 How does the brain represent time? 01:33:23.458 --> 01:33:25.158 What is consciousness? 01:33:25.158 --> 01:33:27.701 >> If we do manage to answer these questions, 01:33:27.701 --> 01:33:30.412 over the course of perhaps one more lifetime, 01:33:30.412 --> 01:33:32.450 what will this mean for the brain? 01:33:32.450 --> 01:33:35.301 An organ that is so complicated and so often 01:33:35.301 --> 01:33:37.914 driven by primitive instincts. 01:33:37.914 --> 01:33:40.733 >> We evolved in a world very different than the 01:33:40.733 --> 01:33:45.354 world we live in today so we have to adapt - now. 01:33:45.354 --> 01:33:47.192 And this to me is the greatest mystery 01:33:47.192 --> 99:59:59.999 of neuroscience right now-
