very important, especially the comparison of vertebrate and invertebrate transduction mechanisms. The workshop was very successful and the outcome of the discussions proved it worth the effort. To no small extent has that success been made possible by Dr. Silke Bernhard who with a combination of authority and charm together with her extremely efficient and dedicated staff organized this workshop, providing the conditions and framework for a scientific debate of outstanding quality in a friendly and pleasant atmosphere. The great majority of participants were also very committed to making this workshop successful. Besides the reports of the four discussion groups, this publication contains the background papers which were revised by the authors partly as a result of suggestions of some participants. I hope this book will give a fair overview of the state of our knowledge of research in visual transduction. It was a pleasure to edit, especially because of the friendly and very efficient commitment of K. Geue, J. Lupp, and A. Eckert and the cooperativeness of most of the contributors. Particularly I would like to acknowledge gratefully the extensive efforts and patience of the four rapporteurs, M.L. Applebury, W.H. Miller, W.G. Owen, and E.N. Pugh, Jr., in compiling, writing, and revising the group reports. REFERENCES (1) Altman, J. 1985. Sensory transduction, new visions in photoreception. Nature 313: 264-265. (2) Hagins, W.A. 1972.

"The Biology of Mind" is an engaging, multi-disciplinary tour of some of the most exciting areas in comtemporary brain and cognitive science. Appropriate for a wide range of students and general readers, this text considers the evolution of mind and the transition from primate to early hominid to modern intelligence. It also surveys contemporary studies of brain structure and mechanisms that underlie perception, emotions, language, memory, and learning. this new book provides an essential guide to understanding the origins of the human brain and the mysteries of mind and consciousness.

From the pre-publication reviews:
"This book is an unusual blend of material on the biology of mind: not just neuroscience, or just evolution or just philosophy of mind, etc., but rather a balanced mix, a relatively quick and easy way to become oriented...this is just the kind of initial entry point someone outside the field will find useful. I know of nothing that is like this." --Stephen M. Kosslyn Professor of Psychology, Harvard University

"This is a broad-ranging and quite successful attempt to provide a coherent and sprightly view of mind and consciousness. The text is an entertaining as well as information-packed introduction to the 'inner world, ' energizing the enormous appeal the study of the mind/brain has for so many--those who simply want to know themselves (the goal that made psychology for many years the largest undergraduate major), as well as the prospective basic neuroscientist." --George Adelman Editor, "Encyclopedia of Neuroscience"
