Dr. Frances E. Jensen is chair of the department of neurology in the Perelman School of Medicine at the University of Pennsylvania. As a mother, teacher, researcher, clinician, and frequent lecturer to parents and teens, she is in a unique position to explain to readers the workings of the teen brain. In , Dr. Jensen brings to readers the astonishing findings that previously remained buried in academic journals. The root myth scientists believed for years was that the adolescent brain was essentially an adult one, only with fewer miles on it. Over the last decade, however, the scientific community has learned that the teen years encompass vitally important stages of brain development.  Samples of some of the most recent findings include: Dr. Jensen gathers what we’ve discovered about adolescent brain function, wiring, and capacity and explains the science in the contexts of everyday learning and multitasking, stress and memory, sleep, addiction, and decision-making.  In this groundbreaking yet accessible book, these findings also yield practical suggestions that will help adults and teenagers negotiate the mysterious world of adolescent development.
