A coaching session can be compared to the creative process of freestyle rap. Neuroscientists at the National Institute on Deafness and Other Communication Disorders scanned the brains of twelve professional rappers with an fMRI (functional magnetic resonance imaging) machine. The scientists discovered that although the brain’s executive functions were active at the start and end of a song, during freestyle, the parts of the brain responsible for self-monitoring, critiquing, and editing were deactivated. In this context, the researchers explained that the rappers were “freed from the conventional constraints of supervisory attention and executive control,” so sudden insights could easily emerge.1 In other words, the rappers used the executive functions of their cognitive brains as they started rapping to deliberately set the intention of the composition up front. Once they had a sense of where they were going, they switched off their inner critic and analyzer. This allowed for more activity in the inner brain, where the eruption of new ideas—creativity—takes place. As they moved to closing out the song, their cognitive brains came back online to provide a consciously designed ending to the composition.
