00:00:00.113 --> 00:00:02.024


00:00:02.024 --> 00:00:05.011
La musique fait partie de nos vies.

00:00:05.595 --> 00:00:09.401
Elle nous réveille, 
nous motive pendant le sport,

00:00:09.401 --> 00:00:11.280
nous accompagne dans les transports.

00:00:11.834 --> 00:00:13.832
Peu importe de quel genre,

00:00:13.832 --> 00:00:17.234
la musique en soi a la capacité
d'affecter notre humeur et notre corps

00:00:17.234 --> 00:00:18.812
de toutes sortes de manières.

00:00:18.974 --> 00:00:22.136
Nous battons la mesure, nous dansons.

00:00:22.136 --> 00:00:24.916
La musique peut donner des frissons
ou nous faire pleurer.

00:00:24.915 --> 00:00:28.704
La musique active toutes les zones
cartographiées du cerveau.

00:00:28.704 --> 00:00:30.984
Il n'y en pas une seule
à notre connaissance

00:00:30.984 --> 00:00:33.145
que la musique ne touche pas.

00:00:33.145 --> 00:00:34.630
Qu'est-ce que cela veut dire ?

00:00:34.630 --> 00:00:36.666
Que nous fait donc la musique ?

00:00:37.204 --> 00:00:39.578
Pour le découvrir, 
j'ai fait plein de tests

00:00:39.578 --> 00:00:41.831
conçus pour mesurer 
mes réactions à la musique.

00:00:42.592 --> 00:00:45.240
J'ai rencontré des enfants 
dont le cerveau

00:00:45.240 --> 00:00:48.122
pourrait changer après des heures
à faire de la musique.

00:00:48.523 --> 00:00:51.047
J'ai parlé à une psychologue qui,
grâce à la musique,

00:00:51.047 --> 00:00:53.358
a aidé l'ex-membre du Congrès
Gabrielle Giffords

00:00:53.358 --> 00:00:56.159
à réapprendre à parler,
et j'ai eu un aperçu du cerveau

00:00:56.159 --> 00:00:58.705
d'un musicien qui a deux Grammy,
pendant qu'il joue.

00:00:58.705 --> 00:01:00.646
(musique et chant)

00:01:00.646 --> 00:01:03.443
tout ça pour découvrir
l'effet que la musique a sur nous.

00:01:05.192 --> 00:01:07.158
(musique entraînante)

00:01:07.539 --> 00:01:10.041
Que se passe-t-il
quand nous écoutons de la musique ?

00:01:10.041 --> 00:01:13.141
Nous nous sommes rendus
au USC Brain and Creativity Institute.

00:01:13.141 --> 00:01:15.455
où on a regardé sous mon crâne
littéralement

00:01:15.455 --> 00:01:16.922
pour essayer de le découvrir.

00:01:16.922 --> 00:01:19.420
Je vais rentrer dans ce scanner.

00:01:19.420 --> 00:01:21.289
Je vais rentrer dans ce petit tube.

00:01:21.289 --> 00:01:23.306
Ce sera l'image de mon cerveau au repos.

00:01:23.306 --> 00:01:25.191
Ensuite je vais écouter de la musique,

00:01:25.191 --> 00:01:27.103
et on verra
comment mon cerveau réagit.

00:01:27.103 --> 00:01:28.608
Fermez les yeux, détendez-vous

00:01:28.608 --> 00:01:30.785
laissez-vous aller 
avec la musique.

00:01:30.785 --> 00:01:33.269
(musique classique)
(Peter) Voilà ce qu'on a vu.

00:01:33.269 --> 00:01:34.431
Ça, c'est mon cerveau.

00:01:34.431 --> 00:01:37.060
Les zones en rouge
sont plus actives que la moyenne ;

00:01:37.060 --> 00:01:38.507
en bleu, elles le sont moins.

00:01:38.507 --> 00:01:41.806
Comme vous le voyez,
Il y a du rouge partout,

00:01:41.806 --> 00:01:43.826
pas juste dans une seule zone.

00:01:43.826 --> 00:01:45.040
(Daniel) Il y a 25 ans,

00:01:45.040 --> 00:01:48.076
on pensait que le langage
c'est le côté gauche du cerveau

00:01:48.076 --> 00:01:50.136
et la musique,
le côté droit.

00:01:50.136 --> 00:01:53.283
Aujourd'hui, nous avons
de meilleurs outils,

00:01:53.604 --> 00:01:57.435
de l'imagerie de haute résolution
et de meilleures méthodes expérimentales

00:01:57.795 --> 00:02:00.170
et nous avons découvert
que c'est faux.

00:02:00.170 --> 00:02:02.843


00:02:02.843 --> 00:02:04.398


00:02:04.398 --> 00:02:07.018


00:02:07.018 --> 00:02:10.362


00:02:10.362 --> 00:02:12.663


00:02:12.663 --> 00:02:14.929


00:02:14.929 --> 00:02:18.928


00:02:18.928 --> 00:02:20.365


00:02:20.365 --> 00:02:22.560


00:02:22.560 --> 00:02:24.761


00:02:24.761 --> 00:02:27.775


00:02:27.775 --> 00:02:30.229


00:02:30.229 --> 00:02:32.114


00:02:32.114 --> 00:02:34.797


00:02:34.797 --> 00:02:37.138


00:02:37.138 --> 00:02:39.324


00:02:39.324 --> 00:02:41.076


00:02:41.756 --> 00:02:44.245


00:02:44.862 --> 00:02:46.820


00:02:47.147 --> 00:02:50.111


00:02:50.111 --> 00:02:52.255


00:02:52.688 --> 00:02:55.180


00:02:55.180 --> 00:02:58.194


00:02:58.194 --> 00:03:00.857


00:03:00.857 --> 00:03:04.645


00:03:04.645 --> 00:03:05.949


00:03:05.949 --> 00:03:07.497

00:03:25.761 --> 00:03:28.078
