Do you know about music?

Music is strongly associated with the brain's reward system. It's the part of the brain that tells us if things are valuable, or important or relevant to survival, said Robert Zatorre, professor of neurology and neurosurgery at Montreal Neurological Institute. One brain structure in particular, called the striatum, releases a chemical called dopamine in response to pleasure-related stimuli. Imaging of the brain can reveal this process is similar to what happens in your brain in response to food or sex. But unlike those activities, music doesn't have a direct biological survival value. "It's not obvious that it should engage that same system," Zatorre said. Musicians can't see inside their own brains, but they're aware of moments of tension and release in pieces, and that's what arrangers of music do.
