0:00:02.024,0:00:05.011
La musique fait partie de nos vies.

0:00:05.595,0:00:09.401
Elle nous réveille, [br]nous motive pendant le sport,

0:00:09.401,0:00:11.280
nous accompagne dans les transports.

0:00:11.834,0:00:13.832
Peu importe de quel genre,

0:00:13.832,0:00:17.234
la musique en soi a la capacité[br]d'affecter notre humeur et notre corps

0:00:17.234,0:00:18.812
de toutes sortes de manières.

0:00:18.974,0:00:22.136
Nous battons la mesure, nous dansons.

0:00:22.136,0:00:24.916
La musique peut donner des frissons[br]ou nous faire pleurer.

0:00:24.915,0:00:28.704
La musique active toutes les zones[br]cartographiées du cerveau.

0:00:28.704,0:00:30.984
Il n'y en pas une seule[br]à notre connaissance

0:00:30.984,0:00:33.145
que la musique ne touche pas.

0:00:33.145,0:00:34.630
Qu'est-ce que cela veut dire ?

0:00:34.630,0:00:36.666
Que nous fait donc la musique ?

0:00:37.204,0:00:39.578
Pour le découvrir, [br]j'ai fait plein de tests

0:00:39.578,0:00:41.831
conçus pour mesurer [br]mes réactions à la musique.

0:00:42.592,0:00:45.240
J'ai rencontré des enfants [br]dont le cerveau

0:00:45.240,0:00:48.122
pourrait changer après des heures[br]à faire de la musique.

0:00:48.523,0:00:51.047
J'ai parlé à une psychologue qui,[br]grâce à la musique,

0:00:51.047,0:00:53.358
a aidé l'ex-membre du Congrès[br]Gabrielle Giffords

0:00:53.358,0:00:56.159
à réapprendre à parler,[br]et j'ai eu un aperçu du cerveau

0:00:56.159,0:00:58.705
d'un musicien qui a deux Grammy,[br]pendant qu'il joue.

0:00:58.705,0:01:00.646
(musique et chant)

0:01:00.646,0:01:03.443
tout ça pour découvrir[br]l'effet que la musique a sur nous.

0:01:05.192,0:01:07.158
(musique entraînante)

0:01:07.539,0:01:10.041
Que se passe-t-il[br]quand nous écoutons de la musique ?

0:01:10.041,0:01:13.141
Nous nous sommes rendus[br]au USC Brain and Creativity Institute.

0:01:13.141,0:01:15.455
où on a regardé sous mon crâne[br]littéralement

0:01:15.455,0:01:16.922
pour essayer de le découvrir.

0:01:16.922,0:01:19.420
Je vais rentrer dans ce scanner.

0:01:19.420,0:01:21.289
Je vais rentrer dans ce petit tube.

0:01:21.289,0:01:23.306
Ce sera l'image de mon cerveau au repos.

0:01:23.306,0:01:25.191
Ensuite je vais écouter de la musique,

0:01:25.191,0:01:27.103
et on verra[br]comment mon cerveau réagit.

0:01:27.103,0:01:28.608
Fermez les yeux, détendez-vous

0:01:28.608,0:01:30.785
laissez-vous aller [br]avec la musique.

0:01:30.785,0:01:33.269
(musique classique)[br](Peter) Voilà ce qu'on a vu.

0:01:33.269,0:01:34.431
Ça, c'est mon cerveau.

0:01:34.431,0:01:37.060
Les zones en rouge[br]sont plus actives que la moyenne ;

0:01:37.060,0:01:38.507
en bleu, elles le sont moins.

0:01:38.507,0:01:41.806
Comme vous le voyez,[br]Il y a du rouge partout,

0:01:41.806,0:01:43.826
pas juste dans une seule zone.

0:01:43.826,0:01:45.040
(Daniel) Il y a 25 ans,

0:01:45.040,0:01:48.076
on pensait que le langage[br]c'est le côté gauche du cerveau

0:01:48.076,0:01:50.136
et la musique,[br]le côté droit.

0:01:50.136,0:01:53.283
Aujourd'hui, nous avons[br]de meilleurs outils,

0:01:53.604,0:01:57.435
de l'imagerie de haute résolution[br]et de meilleures méthodes expérimentales

0:01:57.795,0:02:00.170
et nous avons découvert[br]que c'est faux.
