"Jean-Pierre Changeux ... explores the fascinating question of how the human brain, similar in so many ways to the brains of less developed species, is able to accomplish so much more... [He] presents his ... view with verve, conviction, and an admirable lucidity."--Richard Restak, Washington Post Book World "An outstanding attempt to convey to the general public an interdisciplinary understanding of the human nervous system."--Nature
