Music of the Hemispheres - New York Times

Very interesting article about how our brains process music. Not as scientific as it may seem offhand.

Ah..... Dopamine.

Music of the Hemispheres - New York Times: "Observing 13 subjects who listened to classical music while in an M.R.I. machine, the scientists found a cascade of brain-chemical activity. First the music triggered the forebrain, as it analyzed the structure and meaning of the tune. Then the nucleus accumbus and ventral tegmental area activated to release dopamine, a chemical that triggers the brain’s sense of reward.

The cerebellum, an area normally associated with physical movement, reacted too, responding to what Dr. Levitin suspected was the brain’s predictions of where the song was going to go. As the brain internalizes the tempo, rhythm and emotional peaks of a song, the cerebellum begins reacting every time the song produces tension (that is, subtle deviations from its normal melody or tempo).

“When we saw all this activity going on precisely in sync, in this order, we knew we had the smoking gun,” he said. “We’ve always known that music is good for improving your mood. But this showed precisely how it happens.”"
