The Neostriatum presents the puzzles of the neostriatum from many different angles. This book presents significant findings concerning the structure and neurotransmitters of the neostriatum. Organized into four parts encompassing 20 chapters, this book begins with an overview of the basic organization of the neostriatum. This text then illustrates an impressive complexity of extrinsic and intrinsic neostriatum circuitry. Other chapters consider the view that the nervous system evolved as a hierarchy, so that non-cortical structures such as the corpus striatum retain their structure and function even when the latter is made subservient to more developed mechanisms of the cerebral cortex. This book discusses as well the behavioral roles of the neostriatum and reviews the behavioral data obtained with each of the major treatment and recording techniques. The final chapter deals with the important features of striatal functions. This book is a valuable resource for neuropsychopharmacologists, neuropsychologists, neurophysiologists, psychologists, and scientists.
