“I started looking at jazz musicians playing the blues as a way to understand how the creative brain emerges from a neuroscience perspective,” said Charles Limb, associate professor of Otolaryngology-Head and Neck Surgery at John’s Hopkins University.

When musicians go to an improvisation, the brain switches, Limb said, and the lateral prefrontal lobes responsible for conscious self monitoring became less engaged. “Musicians were turning off the self-censoring in the brain so they could generate novel ideas without restrictions,” he said. Interestingly, the improvising brain activates many of the same brain centers as language, reinforcing the idea that the back and forth of improvisation between musicians is akin to its own language.
