Here is a great book concerning the functions of the nervous system, so well written that it is equally adapted for use by medical students, research workers or clinicians. Only the highest praise can be given this work. It is packed with facts and current concepts, well documented, bolstered by an extensive bibliography and easily available through an excellent subject and author index. The historical basis of each phase of neurophysiology introduces the chapters in which anatomy, physiology and suggestions for clinical application are integrated in a scholarly fashion rarely found in textbooks. A summary is appended to each chapter. Lorento de No prepared the chapter on the cyto-architecture of the cerebral cortex and nowhere else is a more authentic account to be found. Neurologists have long awaited such a work;the the book should be used in all medical schools and carefully studied by all neurologists and neurophysiologists.
