On the positive side, this book covers many topics that are often omitted from other texts. For example, few books on neurochemistry discuss anything on anesthetics. Other interesting topics include the chemistry of dreams, ethnobotany, and shamanism. The very fact that these "orphan" topics are covered is wonderful. The basic problem is that only a few pages are devoted to any particular subject. This lack of depth plagues Neurochemistry of Consciousness from beginning to end. Neuroscience is a rapidly evolving area where old concepts are often replaced by new material. This book appropriately does not spend time on outdated material but needs more information on the excellent new material chosen. The items presented are very interesting and well supported by clinical and research references.
