This is one of a rush of new books on this topic of which i am aware. The brain's a weird creature- even to try to understand what it is about is nyh impossible for someone like me with a middle-sized brain. We just have to have faith that the people writing about it have bigger brains than we do. This book, though, is a beauty. It explains in simple language how the brain works and major important aspects of it. It staggered me to read for instance, that when we perceive something 10 times more information travels out than travels in. In other words, we expect to see something and that's what we see- plus or minus what conflicts with our expectations. Some books are too detailed; others not enough. For my brain, this ones just about right, with lots of full-page inserts scattered through out if you want more detailed information on that topic. Having read a few brain books by Susan Greenfield this one has my vote.
