0:00:13.959,0:00:17.094 Did you know that every time[br]musicians pick up their instruments 0:00:17.094,0:00:20.293 there are fireworks going off[br]all over their brain? 0:00:20.293,0:00:22.875 On the outside,[br]they may look calm and focused, 0:00:22.880,0:00:26.867 reading the music and making the precise[br]and practiced movements required. 0:00:26.867,0:00:30.201 But inside their brains,[br]there's a party going on. 0:00:30.201,0:00:31.409 How do we know this? 0:00:31.409,0:00:33.225 Well, in the last few decades, 0:00:33.225,0:00:35.720 neuroscientists have made [br]enormous breakthroughs 0:00:35.720,0:00:40.353 in understanding how our brains work[br]by monitoring them in real time 0:00:40.353,0:00:43.465 with instruments like[br]FMRi and PET scanners. 0:00:43.465,0:00:45.718 When people are hooked up[br]to these machines, 0:00:45.718,0:00:48.624 tasks, such as reading or doing math problems, 0:00:48.624,0:00:51.112 each have corresponding areas[br]of the brain 0:00:51.112,0:00:53.161 where activity can be observed. 0:00:53.161,0:00:56.316 But when researchers got the participants[br]to listen to music, 0:00:56.316,0:00:58.300 they saw fireworks. 0:00:58.300,0:01:01.195 Multiple areas of their brains[br]were lighting up at once, 0:01:01.195,0:01:02.844 as they processed the sound, 0:01:02.844,0:01:05.865 took it apart to understand elements,[br]like melody and rhythm, 0:01:05.865,0:01:10.375 and then put it all back together[br]into unified musical experience. 0:01:10.375,0:01:13.043 And our brains do all this work[br]in the split second 0:01:13.043,0:01:17.587 between when we first hear the music[br]and when our foot starts to tap along. 0:01:17.587,0:01:19.563 But when scientists turn[br]from observing the brains 0:01:19.563,0:01:22.635 of music listeners to those of musicians, 0:01:22.635,0:01:25.916 the little backyard fireworks[br]became a jubilee. 0:01:25.916,0:01:29.038 It turns out that[br]while listening to music engages the brain 0:01:29.038,0:01:31.193 in some pretty interesting activities, 0:01:31.193,0:01:35.518 playing music is the brain's equivalent[br]of a full-body workout. 0:01:35.518,0:01:38.706 The neuroscientists saw multiple areas[br]of the brain light up, 0:01:38.706,0:01:41.638 simultaneously processing different information 0:01:41.638,0:01:46.233 in intricate, interrelated, [br]and astonishingly fast sequences. 0:01:46.233,0:01:49.884 But what is it about making music[br]that sets the brain alight? 0:01:49.884,0:01:54.599 The research is still fairly new,[br]but neuroscientists have a pretty good idea. 0:01:54.599,0:01:59.317 Playing a musical instrument engages[br]practically every area of the brain at once, 0:01:59.317,0:02:03.339 especially the visual, auditory, and motor cortices. 0:02:03.339,0:02:07.781 And as with any other workout,[br]disciplined, structured practice in playing music 0:02:07.781,0:02:11.714 strengthens those brain functions,[br]allowing us to apply that strength 0:02:11.714,0:02:13.619 to other activities. 0:02:13.619,0:02:17.144 The most obvious difference between[br]listening to music and playing it 0:02:17.144,0:02:19.728 is that the latter requires[br]fine motor skills, 0:02:19.728,0:02:22.996 which are controlled[br]in both hemispheres of the brain. 0:02:22.996,0:02:26.137 It also combines the linguistic[br]and mathematical precision, 0:02:26.137,0:02:28.295 in which the left hemisphere[br]is more involved, 0:02:28.295,0:02:32.111 with the novel and creative [br]content that the right excels in. 0:02:32.111,0:02:34.304 For these reasons,[br]playing music has been found 0:02:34.304,0:02:38.884 to increase the volume and activity [br]in the brain's corpus callosum, 0:02:38.884,0:02:41.349 the bridge between the two hemispheres, 0:02:41.349,0:02:46.214 allowing messages to get across the brain[br]faster and through more diverse routes. 0:02:46.214,0:02:48.691 This may allow musicians[br]to solve problems 0:02:48.691,0:02:52.340 more effectively and creatively,[br]in both academic and social settings. 0:02:52.340,0:02:56.240 Because making music also involves[br]crafting and understanding 0:02:56.240,0:02:58.504 its emotional content and message, 0:02:58.504,0:03:02.236 musicians often have higher levels[br]of executive function, 0:03:02.236,0:03:04.261 a category of interlinked tasks 0:03:04.261,0:03:08.031 that includes planning, strategizing, [br]and attention to detail 0:03:08.031,0:03:13.255 and requires simultaneous analysis[br]of both cognitive and emotional aspects. 0:03:13.255,0:03:17.196 This ability also has an impact[br]on how our memory systems work. 0:03:17.196,0:03:20.449 And, indeed, musicians exhibit[br]enhanced memory functions, 0:03:20.449,0:03:25.478 creating, storing, and retrieving memories[br]more quickly and efficiently. 0:03:25.478,0:03:29.232 Studies have found that musicians[br]appear to use their highly connected brains 0:03:29.232,0:03:31.994 to give each memory multiple tags, 0:03:31.994,0:03:37.116 such as a conceptual tag, an emotional tag,[br]an audio tag, and a contextual tag, 0:03:37.116,0:03:39.706 like a good internet search engine. 0:03:39.706,0:03:42.590 So, how do we know that all these benefits[br]are unique to music, 0:03:42.590,0:03:45.317 as opposed to, say, sports or painting? 0:03:45.317,0:03:47.569 Or could it be [br]that people who go into music[br] 0:03:47.569,0:03:49.647 were already smarter to begin with? 0:03:49.647,0:03:53.337 Neuroscientists have explored these issues,[br]but so far, they have found that 0:03:53.337,0:03:57.354 the artistic and aesthetic aspects[br]of learning to play a musical instrument 0:03:57.354,0:04:01.733 are different from any other activity studied,[br]including other arts. 0:04:01.733,0:04:04.268 And several randomized studies[br]of participants, 0:04:04.268,0:04:09.071 who showed the same levels of cognitive function [br]and neural processing at the start, 0:04:09.071,0:04:12.879 found that those who were exposed[br]to a period of music learning 0:04:12.879,0:04:16.733 showed enhancement in multiple brain areas,[br]compared to the others. 0:04:16.733,0:04:19.932 This recent research about[br]the mental benefits of playing music 0:04:19.932,0:04:22.589 has advanced our understanding[br]of mental function, 0:04:22.589,0:04:25.525 revealing the inner rhythms and complex interplay 0:04:25.525,0:04:29.275 that make up the amazing orchestra[br]of our brain.
