Today’s show is on the science of sleep. Specifically, how sleep – or too little of it – affects the growing brains of adolescents. Why do teenagers stay up so late? What sleep schedules are optimal for their learning? We’ll hear from two world experts in adolescent sleep -- Dr. Beth Malow and Dr. Frances Jensen. Dr. Malow is a Professor of Neurology and Pediatrics at Vanderbilt, and the Burry Chair in Cognitive Childhood Development. She directs the sleep division at Vanderbilt University Medical Center and has been a major advocate for policies that promote healthy adolescent sleep patterns. Dr. Jensen is Professor and Chair of Neurology at the Perelman School of Medicine at the University of Pennsylvania, and is President Elect of the American Neurological Association. She has researched the mechanisms of epilepsy, stroke, and adolescent brain development, and is the author of the book “The Teenage Brain.” Drs. Malow and Jensen were interviewed by ANA Investigates producer and UCSF Neurohospitalist, Dr. Megan Richie. Series 1, Episode 15
