An understanding of the nervous system at virtually any level of analysis requires an understanding of its basic building block, the neuron. This book provides the solid foundation of the morphological, biochemical, and biophysical properties of nerve cells. All chapters have been thoroughly revised for this second edition to reflect the significant advances of the past five years. The new edition expands on the network aspects of cellular neurobiology by adding a new chapter, Information Processing in Neural Networks, and on the relation of cell biological processes to various neurological diseases. The new concluding chapter illustrates how the great strides in understanding the biochemical and biophysical properties of nerve cells have led to fundamental insights into important aspects of neurodegenerative disease. Includes two new chapters: Information Processing in Neural Networks - describes the principles of operation of neural networks and the key circuit motifs that are common to many networks in the nervous system. Molecular and Cellular Mechanisms of Neurodegenerative Disease - introduces the progress made in the last 20 years in elucidating the cellular and molecular mechanisms underlying brain disorders, including Amyotrophic Lateral Sclerosis (ALS), Parkinson disease, and Alzheimer's disease.

"Conceptual Breakthroughs in Ethology and Animal Behavior highlights, through concise summaries, the most important discoveries and scientific revolutions in animal behavior. These are assessed for their relative impact on the field and their significance to the forward motion of the science of animal behavior. Eighty short essays capture the moment when a new concept emerged or a publication signaled a paradigm shift. How the new understanding came about is explained, and any continuing controversy or scientific conversation on the issue is highlighted. Behavior is a rich and varied field, drawing on genetics, evolution, physiology, and ecology to inform its principles, and this book embraces the wealth of knowledge that comes from the unification of these fields around the study of animals in motion."--Publisher description.

That time is both a dimension of behaviour and a ubiquitous controlling variable in the lives of all living things has been well recognized for many years. The last decade has seen a burgeoning of interest in the quantitative analysis of timing behaviour, and progress during the last five or six years has been particularly impressive, with the publication of several major new theoretical contributions. There has also been considerable progress in behavioural methodology during the past decade. In the area of reinforcement schedules, for example, the venerable interresponse-time schedule, fixed-interval peak procedure and interval bisection task have been complemented by a 'second generation' of incisive instruments for analyzing timing behaviour. Another area of recent development is the analysis of the neurobiological substrate of timing behaviour. Several research groups are currently studying the involvement of various central neurotransmitter systems in the timing behaviour, and the ability of centrally acting drugs and discrete brain lesions to alter timing processes. Yet another recent development in timing research is the growing dialogue between two fields that have grown up separately, although, superficially at least, they seem to have much in common: the experimental analysis of 'interval timing', traditionally the province of experimental psychology, and behavioural chronobiology. The last few years have seen a growing interest in the comparative properties of the internal 'clocks' that regulate biobehavioural rhythms with time bases in the circadian range or longer, and those that are entailed in timing of intervals in the range of seconds or minutes. All these areas of research, and others, are represented in the chapters that make up this volume. This book will help to promote further interactions among researchers who hail from disparate disciplines, but who share a common interest in the temporal properties of behaviour.

Contributed chapters by psychologists and behavioral biologists provide a broad coverage of animal behavior, and governing brain processes. Topics covered include: foraging behavior and strategies, economics and psychology, memory of events and space, time perception, expectancies, food preferences and diet selection, behavior variability and the concept of mind. The volume is designed to satisfy an intderdisciplinary audience, embracing the behavioristic tradition, biological and physiological approaches, and evolutionary theory as philosophical underpinnings to the chapters. Also achieved in this work is a good balance between empirical results and theory.
