Most of us have no idea whatÆs really going on inside our heads. Yet brain scientists have uncovered details every business leader, parent, and teacher should knowùlike the need for physical activity to get your brain working its best. 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 forgetùand so important to repeat new knowledge? Is it true that men and women have different brains? In Brain Rules, Dr. John Medina, a molecular biologist, 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 ruleùwhat scientists know for sure about how our brains workùand then offers transformative ideas for our daily lives. MedinaÆs fascinating stories and infectious sense of humor breathe life into brain science. YouÆll learn why Michael Jordan was no good at baseball. YouÆll peer over a surgeonÆs shoulder as he proves that most of us have a Jennifer Aniston neuron. YouÆll meet a boy who has an amazing memory for music but canÆt tie his own shoes. You will discover how: Every brain is wired differently Exercise improves cognition We are designed to never stop learning and exploring Memories are volatile Sleep is powerfully linked with the ability to learn Vision trumps all of the other senses Stress changes the way we learn In the end, youÆll understand how your brain really worksùand how to get the most out of it.
