Your brain on music

Earlier this year, researchers at MIT came up with a new tool for looking at the brain and discovered that music has its own neural pathways, separate from the ones for speech. “Why do we have music?” Dr. Kanwisher said in an interview. “Why do we enjoy it so much and want to dance when we hear it? How early in development can we see this sensitivity to music, and is it tunable with experience? These are the really cool first-order questions we can begin to address.”
