Brains are useful, and fun to trick, but how do they actually work? This big, clear, colorful book explains all the ins and outs of all kinds of brains, from people to flies—how nerves and neurons work, which parts of the brain control what, and exactly what your brain is doing when it sees, smells, remembers, learns, dreams, and looks at optical illusions.  This excellent tour of brains is hosted by some very cute and well-informed mice, whose brains seem very well developed. Now, can I get them to do my homework?
