MUSIC AND THE BRAIN

Lotsa-notes

We all know that certain pieces of music can evoke strong emotional responses in people. Now, a research team from Canada’s McGill University has uncovered evidence that reveals exactly what causes such feelings of euphoria and ecstasy and why music is so important in human society. Using a combination of brain scanning technologies, the study has shown that the same neurotransmitter which is associated with feeling pleasure from sex and food is released in the brain when listening to good music.

That humans can derive intense pleasure from such things as food, drugs, money and sex is well known. All of these feelings of reward generally involve the activity of a certain neurotransmitter in the brain – dopamine. It’s a mechanism that’s necessary for survival, caused by psychoactive drugs or by tangible items which offer secondary rewards of some kind.

Abstract external stimuli, like music or art, can often trigger heightened pleasure responses in people, even though they can’t be thought of as vital for survival or the result of conditioned reinforcement. They are perceived as being rewarding rather than actually having a direct or chemical influence.

Music’s effect on our emotional state is, of course, also well-known – as witnessed by the floods of tears accompanying a moving piece like O Mio Babbino Caro or something from Bach or Beethoven. Previous neuroimaging studies have hinted that the emotion and reward circuits in the brain have a lot to do with the sensations experienced when listening to good music.
