Lateralization in the Nervous System reviews various aspects of lateralization in the nervous system, with emphasis on approaches such as the investigation of turning tendencies and electrocortical indices of hemispheric asymmetry. Experimental paradigms and outcomes that are applicable to both human and nonhuman species are highlighted. This book is comprised of 26 chapters and begins with an overview of functional lateralization in nonhuman species such as monkeys. Brain asymmetry is examined in context with other biological asymmetries in the quest for general mechanisms and principles of lateralization. The problem of inheritance, embryology, and development of asymmetry is also discussed from a variety of environmentalist and nativist perspectives. Highly suggestive invertebrate and avian models for lateralization are presented, along with the evidence for cerebral dominance and handedness in nonhuman species. Human clinical neuropsychological findings, such as the effects of unilateral cortical and thalamic lesions and the syndrome of unilateral neglect, are considered, together with asymmetries in perception and attention. This monograph will be of interest to psychologists (physiological, cognitive, developmental, and clinical), behavioral biologists, neuroscientists, neurologists, and psychiatrists, as well as to scholars and educators from the humanities and social sciences who are concerned with the nature and biological bases of left-right differences in brain, behavior, and thinking.

How and why does the sleeping brain generate dreams? Though the question is old, a paradigm shift is now occurring in the science of sleep and dreaming that is making room for new answers. From brainstem-based models of sleep cycle control, research is moving toward combined brainstem/forebrain models of sleep cognition itself. The book presents five papers by leading scientists at the center of the current firmament, and more than seventy-five commentaries on those papers by nearly all of the other leading authorities in the field. Topics include mechanisms of dreaming and REM sleep, memory consolidation in REM sleep, and an evolutionary hypothesis of the function of dreaming. The papers and commentaries, together with the authors' rejoinders, represent a huge leap forward in our understanding of the sleeping and dreaming brain. The book's multidisciplinary perspective will appeal to students and researchers in neuroscience, cognitive science, and psychology.

This book was first published in 1988. B. F. Skinner was arguably the most important and influential psychologist of the last century. Yet in his long and distinguished career he consistently declined to be engaged by his critics. In his ninth decade, he elected to confront them all: cognitivists, ethologists, brain scientists, biologists, linguists, and philosophers - close to one hundred and fifty scientists and scholars from the entire spectrum of behavior-related disciplines around the world. Skinner's views on consciousness, language, problem solving, evolution, biology, brain function, computers, theory and explanation, presented in six seminal papers, are analyzed, criticized and explained in the 'open peer commentary' format of the Behavioral and Brain Sciences journal. The result is a remarkably lucid and revealing historical record of Skinnerian thinking and its impact on psychology and its allied disciplines. General readers, students, professionals and historians will find this unique intellectual exchange an invaluable resource.
