1 00:00:13,959 --> 00:00:17,094 Did you know that every time musicians pick up their instruments 2 00:00:17,094 --> 00:00:20,293 there are fireworks going off all over their brain? 3 00:00:20,293 --> 00:00:22,875 On the outside, they may look calm and focused, 4 00:00:22,880 --> 00:00:26,867 reading the music and making the precise and practiced movements required. 5 00:00:26,867 --> 00:00:30,201 But inside their brains, there's a party going on. 6 00:00:30,201 --> 00:00:31,409 How do we know this? 7 00:00:31,409 --> 00:00:33,225 Well, in the last few decades, 8 00:00:33,225 --> 00:00:35,720 neuroscientists have made enormous breakthroughs 9 00:00:35,720 --> 00:00:40,353 in understanding how our brains work by monitoring them in real time 10 00:00:40,353 --> 00:00:43,465 with instruments like FMRi and PET scanners. 11 00:00:43,465 --> 00:00:45,718 When people are hooked up to these machines, 12 00:00:45,718 --> 00:00:48,624 tasks, such as reading or doing math problems, 13 00:00:48,624 --> 00:00:51,112 each have corresponding areas of the brain 14 00:00:51,112 --> 00:00:53,161 where activity can be observed. 15 00:00:53,161 --> 00:00:56,316 But when researchers got the participants to listen to music, 16 00:00:56,316 --> 00:00:58,300 they saw fireworks. 17 00:00:58,300 --> 00:01:01,195 Multiple areas of their brains were lighting up at once, 18 00:01:01,195 --> 00:01:02,844 as they processed the sound, 19 00:01:02,844 --> 00:01:05,865 took it apart to understand elements, like melody and rhythm, 20 00:01:05,865 --> 00:01:10,375 and then put it all back together into unified musical experience. 21 00:01:10,375 --> 00:01:13,043 And our brains do all this work in the split second 22 00:01:13,043 --> 00:01:17,587 between when we first hear the music and when our foot starts to tap along. 23 00:01:17,587 --> 00:01:19,563 But when scientists turn from observing the brains 24 00:01:19,563 --> 00:01:22,635 of music listeners to those of musicians, 25 00:01:22,635 --> 00:01:25,916 the little backyard fireworks became a jubilee. 26 00:01:25,916 --> 00:01:29,038 It turns out that while listening to music engages the brain 27 00:01:29,038 --> 00:01:31,193 in some pretty interesting activities, 28 00:01:31,193 --> 00:01:35,518 playing music is the brain's equivalent of a full-body workout. 29 00:01:35,518 --> 00:01:38,706 The neuroscientists saw multiple areas of the brain light up, 30 00:01:38,706 --> 00:01:41,638 simultaneously processing different information 31 00:01:41,638 --> 00:01:46,233 in intricate, interrelated, and astonishingly fast sequences. 32 00:01:46,233 --> 00:01:49,884 But what is it about making music that sets the brain alight? 33 00:01:49,884 --> 00:01:54,599 The research is still fairly new, but neuroscientists have a pretty good idea. 34 00:01:54,599 --> 00:01:59,317 Playing a musical instrument engages practically every area of the brain at once, 35 00:01:59,317 --> 00:02:03,339 especially the visual, auditory, and motor cortices. 36 00:02:03,339 --> 00:02:07,781 And as with any other workout, disciplined, structured practice in playing music 37 00:02:07,781 --> 00:02:11,714 strengthens those brain functions, allowing us to apply that strength 38 00:02:11,714 --> 00:02:13,619 to other activities. 39 00:02:13,619 --> 00:02:17,144 The most obvious difference between listening to music and playing it 40 00:02:17,144 --> 00:02:19,728 is that the latter requires fine motor skills, 41 00:02:19,728 --> 00:02:22,996 which are controlled in both hemispheres of the brain. 42 00:02:22,996 --> 00:02:26,137 It also combines the linguistic and mathematical precision, 43 00:02:26,137 --> 00:02:28,295 in which the left hemisphere is more involved, 44 00:02:28,295 --> 00:02:32,111 with the novel and creative content that the right excels in. 45 00:02:32,111 --> 00:02:34,304 For these reasons, playing music has been found 46 00:02:34,304 --> 00:02:38,884 to increase the volume and activity in the brain's corpus callosum, 47 00:02:38,884 --> 00:02:41,349 the bridge between the two hemispheres, 48 00:02:41,349 --> 00:02:46,214 allowing messages to get across the brain faster and through more diverse routes. 49 00:02:46,214 --> 00:02:48,691 This may allow musicians to solve problems 50 00:02:48,691 --> 00:02:52,340 more effectively and creatively, in both academic and social settings. 51 00:02:52,340 --> 00:02:56,240 Because making music also involves crafting and understanding 52 00:02:56,240 --> 00:02:58,504 its emotional content and message, 53 00:02:58,504 --> 00:03:02,236 musicians often have higher levels of executive function, 54 00:03:02,236 --> 00:03:04,261 a category of interlinked tasks 55 00:03:04,261 --> 00:03:08,031 that includes planning, strategizing, and attention to detail 56 00:03:08,031 --> 00:03:13,255 and requires simultaneous analysis of both cognitive and emotional aspects. 57 00:03:13,255 --> 00:03:17,196 This ability also has an impact on how our memory systems work. 58 00:03:17,196 --> 00:03:20,449 And, indeed, musicians exhibit enhanced memory functions, 59 00:03:20,449 --> 00:03:25,478 creating, storing, and retrieving memories more quickly and efficiently. 60 00:03:25,478 --> 00:03:29,232 Studies have found that musicians appear to use their highly connected brains 61 00:03:29,232 --> 00:03:31,994 to give each memory multiple tags, 62 00:03:31,994 --> 00:03:37,116 such as a conceptual tag, an emotional tag, an audio tag, and a contextual tag, 63 00:03:37,116 --> 00:03:39,706 like a good internet search engine. 64 00:03:39,706 --> 00:03:42,590 So, how do we know that all these benefits are unique to music, 65 00:03:42,590 --> 00:03:45,317 as opposed to, say, sports or painting? 66 00:03:45,317 --> 00:03:47,569 Or could it be that people who go into music 67 00:03:47,569 --> 00:03:49,647 were already smarter to begin with? 68 00:03:49,647 --> 00:03:53,337 Neuroscientists have explored these issues, but so far, they have found that 69 00:03:53,337 --> 00:03:57,354 the artistic and aesthetic aspects of learning to play a musical instrument 70 00:03:57,354 --> 00:04:01,733 are different from any other activity studied, including other arts. 71 00:04:01,733 --> 00:04:04,268 And several randomized studies of participants, 72 00:04:04,268 --> 00:04:09,071 who showed the same levels of cognitive function and neural processing at the start, 73 00:04:09,071 --> 00:04:12,879 found that those who were exposed to a period of music learning 74 00:04:12,879 --> 00:04:16,733 showed enhancement in multiple brain areas, compared to the others. 75 00:04:16,733 --> 00:04:19,932 This recent research about the mental benefits of playing music 76 00:04:19,932 --> 00:04:22,589 has advanced our understanding of mental function, 77 00:04:22,589 --> 00:04:25,525 revealing the inner rhythms and complex interplay 78 00:04:25,525 --> 00:04:29,275 that make up the amazing orchestra of our brain.
