During the past fifteen or twenty years there have been remarkable advances in the methods of study of the functions of the brain in a wide range of species including man. As a result there has been a large increase in the factual knowledge of brain function but the interpretation and the application of these new facts has often tended to lag. The chapters in this book are the formal statements of those specialists of various disciplines who took part in a course of lectures and discussions of methods of the investigation of brain function in May 1980. Not only do they usually indicate the present state of knowledge and comprehension of the many functions of the brain of several species, but they also give valuable indications of where future studies might profitably be directed.
