And....This Is Your Brain on Jazz

A study on brain activity,and what happens when jazz musicians improvise.
Description
A pair of Johns Hopkins and government scientists have discovered that when jazz musicians improvise, their brains turn off areas linked to self-censoring and inhibition, and turn on those that let self-expression flow.
Jazz is often described as being an extremely individualistic art form. You can figure out which jazz musician is playing because one persons improvisation sounds only like him or her.What we think is happening is when you are telling your own musical story, you are shutting down impulses that might impede the flow of novel ideas.
