In this volume, Sarah-Jayne Blakemore explains how our brains develop in our adolescent years and how these changes determine the adults we become. Our personalities, aspirations and dreams are all established in our brains. It creates every feeling, emotion and desire we experience and stores every one of our memories. And yet, until very recently, we believed that it stopped developing in childhood; that by the time you reached adolescence, your brain was fully developed. Here, Sarah-Jayne reveals that is simply not the case.
