WEBVTT 00:00:04.931 --> 00:00:06.760 Thank you, it's a pleasure to be here. 00:00:06.785 --> 00:00:09.258 So I am a surgeon who studies creativity, 00:00:09.282 --> 00:00:12.110 and I have never had a patient tell me, 00:00:12.134 --> 00:00:14.976 "I really want you to be creative during surgery," 00:00:15.000 --> 00:00:17.401 and so I guess there's a little bit of irony to it. 00:00:17.443 --> 00:00:20.743 I will say though that, after having done surgery a lot, 00:00:20.767 --> 00:00:22.977 it's similar to playing a musical instrument. 00:00:23.001 --> 00:00:25.831 And for me, this deep and enduring fascination with sound 00:00:25.855 --> 00:00:27.597 is what led me to both be a surgeon 00:00:27.621 --> 00:00:30.155 and to study the science of sound, particularly music. 00:00:30.179 --> 00:00:32.228 I'm going to talk over the next few minutes 00:00:32.252 --> 00:00:33.543 about my career 00:00:33.567 --> 00:00:35.851 in terms of how I'm able to study music 00:00:35.875 --> 00:00:37.909 and try to grapple with all these questions 00:00:37.933 --> 00:00:40.276 of how the brain is able to be creative. 00:00:41.300 --> 00:00:43.930 I've done most of this work at Johns Hopkins University, 00:00:43.954 --> 00:00:46.939 and at the National Institute of Health where I was previously. 00:00:46.963 --> 00:00:50.470 I'll go over some science experiments and cover three musical experiments. 00:00:50.494 --> 00:00:52.550 I will start off by playing a video for you. 00:00:52.574 --> 00:00:55.677 This video is of Keith Jarrett, who's a well-known jazz improviser 00:00:55.701 --> 00:00:58.744 and probably the most well-known, iconic example 00:00:58.769 --> 00:01:01.761 of someone who takes improvisation to a higher level. 00:01:01.786 --> 00:01:04.925 And he'll improvise entire concerts off the top of his head, 00:01:04.949 --> 00:01:07.354 and he'll never play it exactly the same way again, 00:01:07.378 --> 00:01:09.762 so as a form of intense creativity, 00:01:09.787 --> 00:01:11.405 I think this is a great example. 00:01:11.429 --> 00:01:13.776 And so why don't we go and click the video. 00:01:13.800 --> 00:01:17.800 (Music) 00:02:16.095 --> 00:02:18.096 (Music ends) 00:02:19.920 --> 00:02:22.259 It's really a remarkable thing that happens there. 00:02:23.683 --> 00:02:26.110 I've always as a listener, as a fan, 00:02:26.135 --> 00:02:27.852 I listen to that, and I'm astounded. 00:02:27.876 --> 00:02:29.612 I think -- how can this possibly be? 00:02:29.636 --> 00:02:31.927 How can the brain generate that much information, 00:02:31.951 --> 00:02:33.536 that much music, spontaneously? 00:02:33.560 --> 00:02:36.176 And so I set out with this concept, scientifically, 00:02:36.200 --> 00:02:40.551 that artistic creativity, it's magical, but it's not magic, 00:02:40.575 --> 00:02:42.582 meaning that it's a product of the brain. 00:02:42.606 --> 00:02:45.040 There's not too many brain-dead people creating art. 00:02:45.064 --> 00:02:48.695 With this notion that artistic creativity is in fact a neurologic product, 00:02:48.719 --> 00:02:51.176 I took this thesis that we could study it 00:02:51.200 --> 00:02:54.314 just like we study any other complex neurologic process, 00:02:54.338 --> 00:02:56.393 and there are subquestions that I put there. 00:02:56.417 --> 00:02:59.699 Is it possible to study creativity scientifically? 00:02:59.727 --> 00:03:01.764 And I think that's a good question. 00:03:01.788 --> 00:03:04.474 And I'll tell you that most scientific studies of music, 00:03:05.298 --> 00:03:06.816 they're very dense, 00:03:06.840 --> 00:03:08.235 and when you go through them, 00:03:08.259 --> 00:03:10.329 it's very hard to recognize the music in it. 00:03:10.353 --> 00:03:12.572 In fact, they seem to be unmusical entirely 00:03:12.596 --> 00:03:14.390 and to miss the point of the music. 00:03:15.214 --> 00:03:16.770 This brings the second question: 00:03:16.794 --> 00:03:18.676 Why should scientists study creativity? 00:03:18.700 --> 00:03:20.779 Maybe we're not the right people to do it. 00:03:20.803 --> 00:03:21.802 (Laughter) 00:03:21.826 --> 00:03:25.278 Well it may be, but I will say that, from a scientific perspective, 00:03:25.302 --> 00:03:27.320 we talked a lot about innovation today, 00:03:27.344 --> 00:03:28.676 the science of innovation, 00:03:28.700 --> 00:03:31.653 how much we understand about how the brain is able to innovate 00:03:31.677 --> 00:03:32.921 is in its infancy, 00:03:32.945 --> 00:03:36.412 and truly, we know very little about how we are able to be creative. 00:03:36.436 --> 00:03:37.960 I think that we're going to see, 00:03:37.984 --> 00:03:39.676 over the next 10, 20, 30 years, 00:03:39.700 --> 00:03:41.871 a real science of creativity that's burgeoning 00:03:41.895 --> 00:03:43.096 and is going to flourish, 00:03:43.120 --> 00:03:45.552 Because we now have new methods that can enable us 00:03:45.576 --> 00:03:48.100 to take this process like complex jazz improvisation, 00:03:48.124 --> 00:03:49.498 and study it rigorously. 00:03:49.522 --> 00:03:50.912 So it gets down to the brain. 00:03:50.913 --> 00:03:52.687 All of us have this remarkable brain, 00:03:52.711 --> 00:03:55.166 which is poorly understood, to say the least. 00:03:55.190 --> 00:03:59.388 I think that neuroscientists have more questions than answers, 00:03:59.412 --> 00:04:01.614 and I'm not going to give you answers today, 00:04:01.638 --> 00:04:02.999 just ask a lot of questions. 00:04:03.023 --> 00:04:04.530 And that's what I do in my lab. 00:04:04.554 --> 00:04:07.868 I ask questions about what is the brain doing to enable us to do this. 00:04:07.892 --> 00:04:10.669 This is the main method that I use. This is functional MRI. 00:04:10.693 --> 00:04:13.416 If you've been in an MRI scanner, it's very much the same, 00:04:13.440 --> 00:04:17.355 but this one is outfitted in a special way to not just take pictures of your brain, 00:04:17.379 --> 00:04:20.305 but to also take pictures of active areas of the brain. 00:04:20.329 --> 00:04:22.235 The way that's done is by the following: 00:04:22.259 --> 00:04:24.069 There's something called BOLD imaging, 00:04:24.093 --> 00:04:26.492 which is Blood Oxygen Level Dependent imaging. 00:04:26.881 --> 00:04:30.665 When you're in an fMRI scanner, you're in a big magnet 00:04:30.690 --> 00:04:33.911 that's aligning your molecules in certain areas. 00:04:33.987 --> 00:04:37.706 When an area of the brain is active, meaning a neural area is active, 00:04:37.730 --> 00:04:39.968 it gets blood flow shunted to that area. 00:04:39.992 --> 00:04:44.342 That blood flow causes an increase in local blood to that area 00:04:44.366 --> 00:04:47.349 with a deoxyhemoglobin change in concentration. 00:04:47.373 --> 00:04:49.528 Deoxyhemoglobin can be detected by MRI, 00:04:49.552 --> 00:04:51.402 whereas oxyhemoglobin can't. 00:04:51.426 --> 00:04:53.380 So through this method of inference -- 00:04:53.404 --> 00:04:55.946 and we're measuring blood flow, not neural activity -- 00:04:55.970 --> 00:04:58.706 we say that an area of the brain that's getting more blood 00:04:58.730 --> 00:05:02.272 was active during a particular task, and that's the crux of how fMRI works. 00:05:02.296 --> 00:05:06.875 And it's been used since the '90s to study really complex processes. 00:05:07.225 --> 00:05:11.124 I'm going to review a study that I did, which was jazz in an fMRI scanner. 00:05:11.149 --> 00:05:13.652 It was done with a colleague, Alan Braun, at the NIH. 00:05:13.676 --> 00:05:16.076 This is a short video of how we did this project. 00:05:16.800 --> 00:05:19.581 (Video) Charles Limb: This is a plastic MIDI piano keyboard 00:05:19.605 --> 00:05:21.386 that we use for the jazz experiments. 00:05:21.410 --> 00:05:23.962 And it's a 35-key keyboard 00:05:23.987 --> 00:05:26.447 designed to fit both inside the scanner, 00:05:26.471 --> 00:05:27.807 be magnetically safe, 00:05:27.831 --> 00:05:31.673 have minimal interference that would contribute to any artifact, 00:05:31.697 --> 00:05:34.617 and have this cushion so that it can rest on the players' legs 00:05:34.641 --> 00:05:37.596 while they're lying down in the scanner, playing on their back. 00:05:37.620 --> 00:05:40.649 It works like this -- this doesn't actually produce any sound. 00:05:40.673 --> 00:05:43.116 It sends out what's called a MIDI signal -- 00:05:43.140 --> 00:05:45.189 or a Musical Instrument Digital Interface -- 00:05:45.213 --> 00:05:47.874 through these wires into the box and then the computer, 00:05:47.898 --> 00:05:50.833 which then trigger high-quality piano samples like this. 00:05:50.857 --> 00:05:52.863 (Music) 00:05:52.886 --> 00:05:55.086 Now I'm going to demo it for you. 00:05:55.987 --> 00:05:58.190 I'm using two mirrors to see my fingers. 00:05:58.215 --> 00:06:01.969 (Music) 00:06:20.766 --> 00:06:22.033 This is improvized. 00:06:36.732 --> 00:06:38.707 (Music ends) 00:06:38.732 --> 00:06:40.376 OK, so it works. 00:06:40.400 --> 00:06:42.376 And so through this piano keyboard, 00:06:42.400 --> 00:06:45.143 we have the means to take a musical process and study it. 00:06:45.167 --> 00:06:48.094 So what do you do now that you have this cool piano keyboard? 00:06:48.118 --> 00:06:50.563 You can't just say, "It's great we have a keyboard." 00:06:50.587 --> 00:06:52.911 We have to come up with a scientific experiment. 00:06:52.935 --> 00:06:55.058 The experiment really rests on the following: 00:06:55.329 --> 00:06:58.973 What happens in the brain during something that's memorized and over-learned, 00:06:58.997 --> 00:07:01.152 and what happens in the brain during something 00:07:01.176 --> 00:07:03.450 that is spontaneously generated, or improvised, 00:07:03.474 --> 00:07:05.288 in a way that's matched motorically 00:07:05.312 --> 00:07:08.157 and in terms of lower-level sensory motor features? 00:07:08.181 --> 00:07:10.776 I have here what we call the paradigms. 00:07:10.800 --> 00:07:14.296 There's a scale paradigm, which is playing a scale up and down, memorized, 00:07:14.320 --> 00:07:16.054 then there's improvising on a scale, 00:07:16.078 --> 00:07:18.115 quarter notes, metronome, right hand -- 00:07:18.139 --> 00:07:19.710 scientifically very safe, 00:07:19.734 --> 00:07:21.607 but musically really boring. 00:07:22.031 --> 00:07:25.002 Then there's the bottom one, which is called the jazz paradigm. 00:07:25.026 --> 00:07:27.430 So we brought professional jazz players to the NIH, 00:07:27.454 --> 00:07:30.407 and we had them memorize this piece of music on the lower-left, 00:07:30.431 --> 00:07:32.249 which is what you heard me playing -- 00:07:32.273 --> 00:07:34.766 and we had them improvise to the same chord changes. 00:07:34.790 --> 00:07:36.998 And if you can hit that lower-right sound icon, 00:07:37.022 --> 00:07:39.850 that's an example of what was recorded in the scanner. 00:07:39.874 --> 00:07:43.604 (Music) 00:08:04.604 --> 00:08:06.605 (Music ends) 00:08:06.629 --> 00:08:09.045 In the end, it's not the most natural environment, 00:08:09.069 --> 00:08:10.975 but they're able to play real music. 00:08:10.999 --> 00:08:12.970 And I've listened to that solo 200 times, 00:08:12.994 --> 00:08:14.171 and I still like it. 00:08:14.195 --> 00:08:16.582 And the musicians were comfortable in the end. 00:08:16.606 --> 00:08:18.430 We first measured the number of notes. 00:08:18.454 --> 00:08:21.111 Were they playing more notes when they were improvising? 00:08:21.135 --> 00:08:22.725 That was not what was going on. 00:08:22.749 --> 00:08:24.734 And then we looked at the brain activity. 00:08:24.758 --> 00:08:26.566 I will try to condense this for you. 00:08:26.590 --> 00:08:30.070 These are contrast maps that are showing subtractions between what changes 00:08:30.094 --> 00:08:33.190 when you're improvising vs. when you're doing something memorized. 00:08:33.214 --> 00:08:35.999 In red is an area that's active in the prefrontal cortex, 00:08:36.023 --> 00:08:37.482 the frontal lobe of the brain, 00:08:37.506 --> 00:08:39.684 and in blue is this area that was deactivated. 00:08:39.708 --> 00:08:42.585 So we had this focal area called the medial prefrontal cortex 00:08:42.609 --> 00:08:43.996 that went way up in activity. 00:08:44.020 --> 00:08:47.250 We had this broad patch of area called the lateral prefrontal cortex 00:08:47.274 --> 00:08:48.799 that went way down in activity, 00:08:48.823 --> 00:08:50.311 I'll summarize that for you. 00:08:50.335 --> 00:08:52.443 These are multifunctional areas of the brain, 00:08:52.467 --> 00:08:54.622 these are not the jazz areas of the brain. 00:08:54.646 --> 00:08:56.574 They do a whole host of things 00:08:56.598 --> 00:08:58.457 that have to do with self-reflection, 00:08:58.481 --> 00:09:00.841 introspection, working memory etc. 00:09:00.865 --> 00:09:03.352 Really, consciousness is seated in the frontal lobe. 00:09:03.376 --> 00:09:05.410 But we have this combination 00:09:05.434 --> 00:09:08.883 of an area that's thought to be involved in self-monitoring, turning off, 00:09:08.907 --> 00:09:11.370 and this area that's thought to be autobiographical, 00:09:11.394 --> 00:09:12.929 or self-expressive, turning on. 00:09:12.953 --> 00:09:15.024 We think, at least in this preliminary -- 00:09:15.048 --> 00:09:17.801 it's one study; it's probably wrong, but it's one study -- 00:09:17.825 --> 00:09:18.864 (Laughter) 00:09:18.888 --> 00:09:21.619 we think that at least a reasonable hypothesis 00:09:21.643 --> 00:09:22.804 is that, to be creative, 00:09:22.828 --> 00:09:25.704 you should have this weird dissociation in your frontal lobe. 00:09:25.728 --> 00:09:28.252 One area turns on, and a big area shuts off, 00:09:28.276 --> 00:09:31.214 so that you're not inhibited, you're willing to make mistakes, 00:09:31.238 --> 00:09:33.406 so that you're not constantly shutting down 00:09:33.430 --> 00:09:35.355 all of these new generative impulses. 00:09:35.379 --> 00:09:39.923 Now a lot of people know that music is not always a solo activity -- 00:09:39.948 --> 00:09:41.668 sometimes it's done communicatively. 00:09:42.092 --> 00:09:43.276 The next question was: 00:09:43.300 --> 00:09:45.872 What happens when musicians are trading back and forth, 00:09:45.896 --> 00:09:47.509 something called "trading fours," 00:09:47.533 --> 00:09:50.356 which is something they do normally in a jazz experiment. 00:09:50.380 --> 00:09:51.793 So this is a 12-bar blues, 00:09:51.817 --> 00:09:53.926 and I've broken it down into four-bar groups, 00:09:53.950 --> 00:09:55.762 so you would know how you would trade. 00:09:55.786 --> 00:09:58.271 We brought a musician into the scanner, same way, 00:09:58.296 --> 00:09:59.708 had them memorize this melody 00:09:59.732 --> 00:10:02.298 then had another musician out in the control room 00:10:02.322 --> 00:10:04.291 trading back and forth interactively. 00:10:07.838 --> 00:10:09.925 This is another video I'll show you of this. 00:10:09.957 --> 00:10:11.005 (Music) 00:10:11.015 --> 00:10:12.593 So this is a musician, Mike Pope, 00:10:12.618 --> 00:10:15.649 one of the world's best bassists and a fantastic piano player. 00:10:15.673 --> 00:10:21.369 (Music) 00:10:21.409 --> 00:10:23.722 He's now playing the piece that we just saw 00:10:24.446 --> 00:10:26.176 a little better than I wrote it. 00:10:26.200 --> 00:10:27.966 (Video) CL: Mike, come on in. 00:10:27.990 --> 00:10:29.760 Mike Pope: May the force be with you. 00:10:29.784 --> 00:10:31.550 Nurse: Nothing in your pockets, Mike?
