We have a combination of an area that’s thought to be involved in self-monitoring turning off, and this area that’s thought to be autobiographical, or self-expressive, turning on. A reasonable hypothesis is that to be creative, you have to have this weird disassociation in your frontal lobe. One area turns on, and a big area shuts off so that you’re not inhibited; so that you’re willing to make mistakes; so that you’re not constantly shutting down all of these new generative impulses.
