Most of us have no idea what's really going on inside our heads. Yet brain scientists have uncovered details every business leader, parent, and teacher should know--such as the brain's need for physical activity to work at 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 forget--and so important to repeat new information? Is it true that men and women have different brains? In Brain Rules , molecular biologist Dr. 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. Medina's fascinating stories and sense of humor breathe life into brain science. You'll learn why Michael Jordan was no good at baseball. You'll peer over a surgeon's shoulder as he finds, to his surprise, that we have a Jennifer Aniston neuron. You'll meet a boy who has an amazing memory for music but can't 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, you'll understand how your brain really works--and how to get the most out of it.
“We now know that the space between repetitions is the critical component for transforming temporary memories into more persistent forms”
“We learn and remember best through pictures, not through written or spoken words”
“The brain is in a constant state of tension between cells and chemicals that try to put you to sleep and cells and chemicals that try to keep you awake”
“Spaced learning is greatly superior to massed learning”
“You can responsibly train a skeptical eye on any claim that brain research can without equivocation tell us how to become better teachers, parents, business leaders, or students. This book is a call for research simply because we don’t' know enough to be prescriptive. It is an attempt to vaccinate against mythologies such as the "Mozart Effect," left brain/right brain personalities, and getting your babies into Harvard by making them listen to language tapes while they are still in the womb."”
“Often called the father of sleep research, Dement is a white-haired man with a broad smile who at this writing is in his late 70s. He says pithy things about our slumbering habits, such as "Dreaming permits each and every one of us to be quietly and safely insane every night of our lives."”
Studies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.Highlighted by 665 Kindle customers

Deliberately re-expose yourself to the information if you want to retrieve it later. Deliberately re-expose yourself to the information more elaborately if you want the retrieval to be of higher quality. Deliberately re-expose yourself to the information more elaborately, and in fixed, spaced intervals, if you want the retrieval to be the most vivid it can be.Highlighted by 606 Kindle customers

A lifetime of exercise can result in a sometimes astonishing elevation in cognitive performance, compared with those who are sedentary.Highlighted by 592 Kindle customers
Whether you are a waiter or a brain scientist, if you want to get the particulars correct, don’t start with details. Start with the key ideas and, in a hierarchical fashion, form the details around these larger notions.Highlighted by 546 Kindle customers
The brain appears to be designed to solve problems related to surviving in an unstable outdoor environment, and to do so in nearly constant motion. I call this the brain’s performance envelope.Highlighted by 478 Kindle customers
We think it’s because exercise regulates the release of the three neurotransmitters most commonly associated with the maintenance of mental health: serotonin, dopamine, and norepinephrine.Highlighted by 458 Kindle customers
The brain represents only about 2 percent of most people’s body weight, yet it accounts for about 20 percent of the body’s total energy usage—about 10 times more than would be expected. When the brain is fully working, it uses more energy per unit of tissue weight than a fully exercising quadricep. In fact, the human brain cannot simultaneously activate more than 2 percent of its neurons at any one time. More than this, and the glucose supply becomes so quickly exhausted that you will faint.Highlighted by 409 Kindle customers
