Thanks for this Janice.
"I realized that I obviously couldn’t capture the entire creative process—instead, I could home in on the parts of the brain that make creativity possible."
That's a crucial and fair admission. We mustn't forget the mind and the complete mystery of consciousness which science still tends to regard (almost superstitiously) as originating in the brain. The heart plays a role in consciousness as do probably other organs of the body. Thus you have to think creativity is not the exclusive province of brain IQ and that consciousness plays some role in the creative process.
