The medical reader who opens a book and realizes that a long hidden mystery of the human body stands revealed experiences the sort of thrill which must have chilled the spines of Columbus and Magellan when they first looked on unexplored lands. The brain is the most intricate and important organ in the body, and the most securely protected. But electrical science has opened doors of understanding which would never yield to the scalpel or the microscope. The success of this modern adventure is set forth in Dr. and Mrs. Gibbs's book. The idea of a voyage over uncharted seas is suggested by the body of the book, 104 pages filled with undulating lines. These are life-sized reproductions of tracings of the electrical waves which arise in the cortex of normal persons and of patients. Sample tracings are given of normal persons of various ages and under various physiologic conditions.
