Your brain is the control center for everything you do. A nerve is composed of a bundle of neurons; nerves are the body's wiring. Messages leap from one to another across a tiny gap called a synapse.A message called a response is fired off by a nerve cell by a stimulus, such as touch, sound, light, taste, temperature and smell. Nerve cells that respond to these stimuli are called sensory neurons. The bones that protect your brain are called a cranium. The human brain weighs about three pounds when grown and is about the size of a large grapefruit. Your brain has three main sections: the cerebrum, the cerebellum and the brain stem. How is your memory? If you can remember what you had for breakfast this morning, that's called a short-term memory. Long-term memory is remembering things that happened to you months or years ago. Your brain is like a computer, in fact, it is more effective and can do more jobs than the most powerful computer made. Brains are what make us who we are. This book is much more complicated than this; I've just listed the most important points. It is a very thorough book, and I would recommend its reading!
