The contents of this book are the presentations of a Symposium on "Memory and Transfer of Information", held at Gottingen, May 24-26, 1972 . One of the main reasons for organizing this Symposium was to stimulate interdisciplinary discussion between sci entists working in the field as a whole. Most of the pre vious meetings dealing with memory and transfer of infor mation have tended to be rather limited in scope. The pres ent Symposium covered a wide range of topics, including neurophysiological, neuropharmacological, neurochemical, behavioral and clinical aspects of learning and chemical transfer of information, presented by specialists in these areas. The Proceedings of the meeting present a large number of previously unpublished results, e.g., recent experiments in neurophysiology and neurochemistry, new approaches to chemical transfer of learned information, experiments using synthetic scotophobin and drugs influencing learning and behavior. The importance of interdisciplinary discussion is perhaps most clearly emphasized by the advances in neuro chemical micromethods which are of particular interest to scientists working on the chemical transfer of information. Only such interdisciplinary collaboration between highly specialized scientists guarantees further progress and deeper insight into the complex, and until now little under stood, mechanisms of that most intricate of organs, the brain.
