Brain: A 21st Century Look at a 400 Million Year Old Organ [Hardcover]

Brain: A 21st Century Look at a 400 Million Year Old Organ (Bunker Hill Publishing; available: October 2010) is the companion volume to the highly acclaimed Bones, Brains and DNA, and is based on a new exhibit at the American Museum of Natural History that opens November 3rd, 2010. Is the brain something that works the way it is supposed to like a?computer or something that works not quite as well as it is supposed to like a Rube Goldberg contraption?
