0:00:13.712,0:00:17.070 Did you know that every time[br]musicians pick up their instruments, 0:00:17.094,0:00:20.269 there are fireworks going off[br]all over their brain? 0:00:20.293,0:00:22.856 On the outside,[br]they may look calm and focused, 0:00:22.880,0:00:26.843 reading the music and making the precise[br]and practiced movements required. 0:00:26.867,0:00:29.354 But inside their brains,[br]there's a party going on. 0:00:30.121,0:00:31.385 How do we know this? 0:00:31.409,0:00:33.201 Well, in the last few decades, 0:00:33.225,0:00:35.696 neuroscientists have made[br]enormous breakthroughs 0:00:35.720,0:00:40.329 in understanding how our brains work[br]by monitoring them in real time 0:00:40.353,0:00:43.441 with instruments like[br]fMRI and PET scanners. 0:00:43.465,0:00:45.694 When people are hooked up[br]to these machines, 0:00:45.718,0:00:48.600 tasks, such as reading[br]or doing math problems, 0:00:48.624,0:00:53.010 each have corresponding areas of the brain[br]where activity can be observed. 0:00:53.034,0:00:56.292 But when researchers got[br]the participants to listen to music, 0:00:56.316,0:00:58.276 they saw fireworks. 0:00:58.300,0:01:01.171 Multiple areas of their brains[br]were lighting up at once, 0:01:01.195,0:01:02.820 as they processed the sound, 0:01:02.844,0:01:05.841 took it apart to understand elements[br]like melody and rhythm, 0:01:05.865,0:01:10.028 and then put it all back together[br]into unified musical experience. 0:01:10.052,0:01:13.019 And our brains do all this work[br]in the split second 0:01:13.043,0:01:17.385 between when we first hear the music[br]and when our foot starts to tap along. 0:01:17.409,0:01:19.921 But when scientists turned[br]from observing the brains 0:01:19.945,0:01:22.611 of music listeners to those of musicians, 0:01:22.635,0:01:25.892 the little backyard fireworks[br]became a jubilee. 0:01:25.916,0:01:29.447 It turns out that while listening[br]to music engages the brain 0:01:29.471,0:01:31.429 in some pretty interesting activities, 0:01:31.453,0:01:35.494 playing music is the brain's equivalent[br]of a full-body workout. 0:01:35.518,0:01:38.682 The neuroscientists saw[br]multiple areas of the brain light up, 0:01:38.706,0:01:41.614 simultaneously processing[br]different information 0:01:41.638,0:01:45.508 in intricate, interrelated,[br]and astonishingly fast sequences. 0:01:46.233,0:01:49.860 But what is it about making music[br]that sets the brain alight? 0:01:49.884,0:01:51.795 The research is still fairly new, 0:01:51.819,0:01:54.476 but neuroscientists[br]have a pretty good idea. 0:01:54.500,0:01:55.928 Playing a musical instrument 0:01:55.952,0:01:59.293 engages practically every area[br]of the brain at once, 0:01:59.317,0:02:03.315 especially the visual,[br]auditory, and motor cortices. 0:02:03.339,0:02:07.757 As with any other workout, disciplined,[br]structured practice in playing music 0:02:07.781,0:02:11.690 strengthens those brain functions,[br]allowing us to apply that strength 0:02:11.714,0:02:13.595 to other activities. 0:02:13.619,0:02:17.120 The most obvious difference between[br]listening to music and playing it 0:02:17.144,0:02:19.704 is that the latter requires[br]fine motor skills, 0:02:19.728,0:02:22.781 which are controlled[br]in both hemispheres of the brain. 0:02:22.805,0:02:26.113 It also combines the linguistic[br]and mathematical precision, 0:02:26.137,0:02:28.382 in which the left hemisphere[br]is more involved, 0:02:28.406,0:02:31.941 with the novel and creative[br]content that the right excels in. 0:02:31.965,0:02:34.280 For these reasons,[br]playing music has been found 0:02:34.304,0:02:38.860 to increase the volume and activity[br]in the brain's corpus callosum, 0:02:38.884,0:02:41.325 the bridge between the two hemispheres, 0:02:41.349,0:02:46.190 allowing messages to get across the brain[br]faster and through more diverse routes. 0:02:46.214,0:02:48.667 This may allow musicians to solve problems 0:02:48.691,0:02:52.316 more effectively and creatively,[br]in both academic and social settings. 0:02:52.340,0:02:56.216 Because making music also involves[br]crafting and understanding 0:02:56.240,0:02:58.315 its emotional content and message, 0:02:58.339,0:03:02.212 musicians often have higher levels[br]of executive function, 0:03:02.236,0:03:04.237 a category of interlinked tasks 0:03:04.261,0:03:07.896 that includes planning, strategizing,[br]and attention to detail 0:03:07.920,0:03:13.231 and requires simultaneous analysis[br]of both cognitive and emotional aspects. 0:03:13.255,0:03:16.478 This ability also has an impact[br]on how our memory systems work. 0:03:17.196,0:03:20.425 And, indeed, musicians exhibit[br]enhanced memory functions, 0:03:20.449,0:03:25.454 creating, storing, and retrieving memories[br]more quickly and efficiently. 0:03:25.478,0:03:29.208 Studies have found that musicians appear[br]to use their highly connected brains 0:03:29.232,0:03:31.970 to give each memory multiple tags, 0:03:31.994,0:03:34.310 such as a conceptual tag,[br]an emotional tag, 0:03:34.334,0:03:36.850 an audio tag, and a contextual tag, 0:03:36.874,0:03:38.579 like a good Internet search engine. 0:03:39.706,0:03:42.659 How do we know that all these benefits[br]are unique to music, 0:03:42.683,0:03:45.148 as opposed to, say, sports or painting? 0:03:45.172,0:03:47.545 Or could it be[br]that people who go into music 0:03:47.569,0:03:49.474 were already smarter to begin with? 0:03:49.498,0:03:52.679 Neuroscientists have explored[br]these issues, but so far, 0:03:52.703,0:03:55.353 they have found that the artistic[br]and aesthetic aspects 0:03:55.377,0:03:57.330 of learning to play a musical instrument 0:03:57.354,0:04:01.709 are different from any other activity[br]studied, including other arts. 0:04:01.733,0:04:04.244 And several randomized studies[br]of participants, 0:04:04.268,0:04:05.670 who showed the same levels 0:04:05.694,0:04:09.047 of cognitive function[br]and neural processing at the start, 0:04:09.071,0:04:12.855 found that those who were exposed[br]to a period of music learning 0:04:12.879,0:04:16.183 showed enhancement in multiple[br]brain areas, compared to the others. 0:04:16.889,0:04:19.908 This recent research about[br]the mental benefits of playing music 0:04:19.932,0:04:22.565 has advanced our understanding[br]of mental function, 0:04:22.589,0:04:25.501 revealing the inner rhythms[br]and complex interplay 0:04:25.525,0:04:28.493 that make up the amazing[br]orchestra of our brain.
