Spatial Neglect is one of the few areas in Neuropsychology where clinicians, psychologists and animal experimenters have succeeded in adopting a common language. The result of interaction between these three approaches has been some important new advances, which are presented in this volume. Apart from its clinical significance in neuropsychology, Spatial Neglect raises important questions in the field of behavioral neurosciences. In this volume, three aspects are examined: a) normal subjects, where new findings on spatial behavior are described. b) brain-lesioned subjects, where the classical studies on neglect are reconsidered in the light of new findings. c) animals, where new experimental situations allow a deeper understanding of the neural substrate.

Written by an international team of leading experts in neuroscience, this book presents an overview of some of the main schools of thought as well as current research trends in neuroscience. It focuses on neural top-down causation applied to hot topics like consciousness, emotions, the self and the will, action and behavior, neural networks, brains and society. A special feature of the book is pertinent presentations and lively discussions on the topic. The book provides the reader with invaluable information on what the latest research is in this field and will enable the reader to gain considerable amount of knowledge as well as hints for further enquiry. This is the first book on the topic of neuroscience and top-down causation, and is written at a level that will interest both academics and the general readers. The extensive and lively discussions included in the book offer the reader a clear idea of the research in this field, and what will emerge as the main trends.

Compiled as a result of the Thirteenth Symposium of the Association for Attention and Performance, this collection focuses on the Symposium's theme: Organization of Action. The book is arranged in sections which provide a comprehensive view of the main issues raised during the meeting. Several aspects of the theme were considered, including: the anatomical and physiological constraints on motor preparation and execution . the influence of control (proprioceptive, cutaneous, visual, oculomotor) signals the contribution of kinematics to the understanding of the underlying mechanisms and the role of cognitive constraints such as attention or learning in goal selection This new volume is of particular interest to professionals and researchers in cognitive psychology, physiology, and neuropsychology as well as those studying motor skills.

This volume contains chapters derived from a N. A. T. O. Advanced Study Institute held in June 1983. As the director of this A. S. I. it was my hope that some of the e1ectrophysiologists could express the potentialities of their work for perceptual theory, and that some perceptionists could speculate on the underlying "units" of perception in a way that would engage the imagination of physio logists. The reader will have to be the judge of whether this was achieved, or whether such a psychophysiological inter1ingua is still overly idealistic. It is clear that after the revolution prec pitated by Hube1 and Weisel in understanding of visual cortical neurons we still have only a foggy idea of the behavioral output of any particular species of cortical detector. It was therefore particularly unfortunate that two persons who have made great strides in correlating interesting facets of cat cortical physio logy with human psychophysics (Max Cynader and Martin Regan of Dalhousie University) were unable to attend this meeting. Never theless, a number of new and challenging ideas regarding both spatial perception and cortical mechanisms are represented in this volume, and it is hoped that the reader will remember not only the individual demonstrations but the critical questions posed by the apposition of the two different collections of experimental facts.

'Motor Cognition' describes the field of motor cognition - one to which the author's contribution has been seminal. The book examines how the motor actions we perform and watch others perform play a pivotal role in the construction of the 'self' - our ability to acknowledge and recognise our own identity.

This is the first book to offer a comprehensive overview of higher-order motor disorders. It introduces new concepts emerging from basic neurosciences and shows how they have impacted on the field of cognitive motor control and led to new vistas for the understanding of Higher-order Motor Disorders far beyond the traditional field of topological diagnosis. It describes in detail a wide range of clinical disorders including those of bimanual co-ordination, apraxia and sensorimotor transformation deficits, motor neglect, anarchic hand syndrome, imitation and utilisation behaviours, action motivational and action monitoring disorders, as well as new approaches to motor cortex plasticity and reorganisation and rehalibitation of complex movement problems. The book reviews the topic, starting with a description of the neuroanatomical, neurobiological and cognitive basis of normal motor behaviours, before moving on to cover the clinical features of the disordered states. The final chapters cover the issues of plastcity and recovery, pharmacological treatments and rehabilitation.
This volume will stimulate research and foster new insights into cognitive and motivational motor disorders. With expert contributions from the major international centres in Europe and the Americas his book gives a truly new framework for a complex and confusing field.

Recent neuroscience, in replacing the old model of the brain as a single centralized source of control, has emphasized "plasticity," the quality by which our brains develop and change throughout the course of our lives. Our brains exist as historical products, developing in interaction with themselves and with their surroundings. Hence there is a thin line between the organization of the nervous system and the political and social organization that both conditions and is conditioned by human experience. Looking carefully at contemporary neuroscience, it is hard not to notice that the new way of talking about the brain mirrors the management discourse of the neo-liberal capitalist world in which we now live, with its talk of decentralization, networks, and flexibility. Consciously or unconsciously, science cannot but echo the world in which it takes place. In the neo-liberal world, "plasticity" can be equated with "flexibility"-a term that has become a buzzword in economics and management theory. The plastic brain would thus represent just another style of power, which, although less centralized, is still a means of control. In this book, Catherine Malabou develops a second, more radical meaning for plasticity. Not only does plasticity allow our brains to adapt to existing circumstances, it opens a margin of freedom to intervene, to change those very circumstances. Such an understanding opens up a newly transformative aspect of the neurosciences. In insisting on this proximity between the neurosciences and the social sciences, Malabou applies to the brain Marx's well-known phrase about history: people make their own brains, but they do not know it. This book is a summons to such knowledge.

Our ability to acknowledge and recognise our own identity - our 'self' - is a characteristic doubtless unique to humans. Where does this feeling come from? How does the combination of neurophysiological processes coupled with our interaction with the outside world construct this coherent identity? We know that our social interactions contribute via the eyes, ears etc. However, our self is not only influenced by our senses. It is also influenced by the actions we perform and those we see others perform. Our brain anticipates the effects of our own actions and simulates the actions of others. In this way, we become able to understand ourselves and to understand the actions and emotions of others. This book is the first to describe the new field of 'Motor Cognition' - one to which the author's contribution has been seminal. Though motor actions have long been studied by neuroscientists and physiologists, it is only recently that scientists have considered the role of actions in building the self. How consciousness of action is part of self-consciousness, how one's own actions determine the sense of being an agent, how actions performed by others impact on ourselves for understanding others, differentiating ourselves from them and learning from them: these questions are raised and discussed throughout the book, drawing on experimental, clinical, and theoretical bases. The advent of new neuroscience techniques, like neuroimaging and direct electrical brain stimulation, together with a renewal of behavioral methods in cognitive psychology, provide new insights into this area. Mental imagery of action, self-recognition, consciousness of actions, imitation can be objectively studied using these new tools. The results of these investigations shed light on clinical disorders in neurology, psychiatry and in neuro-development. This is a major new work that will lay down the foundations for the field of motor cognition.

Ways of seeing is a book about human vision. It results from the collaboration between a world famous cognitive neuroscientist and an eminent philosopher. In the past forty years, cognitive neuroscience has made many startling discoveries about the human brain, and about the human visual system in particular. This book brings many recent empirical findings, from electrophysiological recordings in animals, the neuropsychological examination of human patients, psychophysics, and developmental cognitive psychology, to bear on questions traditionally addressed by philosophers. What is the meaning of the English verb 'to see'? How does visual perception yield knowledge of the world? How does visual perception relate to thought? What is the role of conscious visual experience in visually guided actions? How does seeing actions relate to seeing objects? In the process the book provides a new assessment of the 'two visual systems' hypothesis, according to which the human visual system comprises two anatomical pathways with separable visual functions. The first truly interdisciplinary book about human vision, it will be of interest to students and researchers in many areas of cognitive science and the philosophy of mind.
