Where does 'creativity' happen in your brain?

Don't go hunting for it as though it were a single entity. Creativity emerges from a variety of mental process and has no precise location

Even in the wilderness that is human thinking, creative ideas seem to be deliberately designed to defy empirical inquiry. There is something elusive, perhaps even mystical, about them - visits from the muse or lightbulbs come to mind.

So what are neuroscientists to do if they want to study inspiration in the lab, under tightly controlled conditions? Clearly, they cannot simply take volunteers, shove them into the nearest brain scanner, and tell them: now please be creative.
