Your brain controls every part of your body, from head to toe. It lets you know when your stomach is empty and when your bladder is full. It converts sound waves into noises recognizable to your ears and upside-down images into right side-up pictures recognizable by your eyes. Even when you're asleep, your brain tells your heart to keep beating and your lungs to keep breathing - and it still has time for a dream or two. This book looks at all aspects of the human body from the vantage point of this amazing control center known as the brain.
