In his Ted Talk (2010), Limb discusses his research on improvisation and creativity in the brains of jazz and hip-hip musicians. Beginning his talk with a video of an improvisation by master jazz pianist Keith Jarrett, Limb then poses the following problem: How can the brain generate so much musical information spontaneously? His talk tries to begin to answer this question by reference to three fMRI studies that examine artistic creativity on a neurological level. He shows video footage of these experiments.
