Richly illustrated with over 100 anatomical drawings, this book provides a functional view of the frontal lobes of the brain. Based on Passingham's work on monkeys and humans, the most modern techniques including PET imaging are discussed. It is the only book available to discuss the frontal cortex as a whole, and with an essential `flow diagram' of the operations of the frontal lobes, this book will be a valuable basis for future work and debate on the subject.
