After reading other books in the Science Masters series by such brilliant authors as Richard Dawkins, and having heard all the hype about Susan Greenfield, I was expecting a lot from this book, and was frankly disappointed to discover that it covered almost exactly the same information, in the same style, as any GCSE level biology text book. There was no mention of Greenfield's current work, nor anything even remotely controversial or cutting-edge - virtually everything in this book has been widely known since the 1960's or before. Potential readers should be clear that while this book would make an acceptable introduction to the brain for novice readers, it never goes beyond the basics and has nothing whatsoever to offer people with pre-existing knowledge of the subject.
