We use our brains every day, but how do they actually control our thoughts, our movements, and our feelings? Does the brain turn itself off at night? Can people who research the brain read minds? In this book, experts respond to 80 questions posed by children about the brain. Their answers reveal astounding information and facts not only about the human brain, but also about the gray matter of earthworms, ants, and sperm whales. Images created by Jan von Holleben with the help of 30 young people capture our personal control rooms in action- as we taste, get scared, study, juggle, and sleepwalk. These fun yet enlightening photographs clearly demonstrate that even when we do nothing at all, our brains are hard at work.
