Dr. Daniel Levitin

While listening to music, neuroscientist Daniel Levitin, asks the questions "where do goose bumps come from?" and "what's going on in my brain that allows the goosebumps to happen?" Levitin leads a group of researchers as they investigate music's fundamental physical structure; its biological, emotional and psychological impact; its brain altering and healing powers and its role in human evolution.
