Most of us have no idea what's really going on inside our heads. How do we learn? What exactly do sleep and stress do to our brains?

Why is multi-tasking a myth? Why is it so easy to forget—and so important to repeat new knowledge? In Brain Rules, molecular biologist John Medina shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work.

In each chapter, he describes a Brain Rule—what scientists know for sure about how our brains work—and then offers transformative ideas for our daily lives. You will discover how:Exercise improves cognitionEvery brain is wired differentlyWe are designed never to stop learning and exploringMemories are volatile and susceptible to corruptionSleep is powerfully linked with the ability to learnVision trumps all of the other sensesStress changes the way we learnIn the end, you'll understand how your brain really works—and how to get the most out of it.
