In recent years, great interest has been focused on the field of neurobiology. In the last decade, various international and regional meetings, symposia, seminars and workshops have been organized to discuss brain regions such as the hypothalamus, cerebellum, medulla, cortex and hippocampus. A number of books have been published as a consequence of these gatherings. Uniquely and singularly absent from these conclaves has been a truly interdisciplinary discussion of the amygdala. The various chapters of this book represent the formal talks presented at The Advanced Study Institute held at the Jackson Laboratory, Bar Harbor, Maine, from June 6 to 17, 1971, with funds made available from the Scientific Affairs Committee of the North Atlantic Treaty Organization and the National Science Foundation. The speakers and participants are grateful to these two institutions for being given the opportunity to gather and discuss their respective works that represent years of experi mental and clinical research centering on the amygdala. It is hoped that the experiments discussed in this book will act as a major stimulus to other scientists to initiate complementary and supplementary experiments for the better understanding of the specific role of the amygdala.
