Book Description
Used for gestures of communication, environmental exploration, and the grasping and manipulating of objects, the hand has a vital role in our lives. The hand's anatomical structure and neural control are among the most complex and detailed of human motor systems. Hand and Brain is a comprehensive overview of the hand's sensorimotor control. It discusses mediating variables in perception and prehension, the coordination of muscles with the central nervous system, the nature of movement control and hand positioning, hand-arm coordination in reaching and grasping, and the sensory function of the hand. In the last decade the rapid growth of neuroscience has been paralleled by a surge of interest in hand function. This reflects the fact that many of the fundamental issues facing neuroscientists today--including the problem of relating physiology to behavior--are central to the study of sensorimotor control of the hand. This book takes a broad interdisciplinary perspective on the control of hand movements that includes neurophysiology, neuroanatomy, psychology and neuropsychology, and biomechanics. The authors, who have all made significant scientific contributions in their own right, have sought to introduce their chosen topics in a manner that the undergraduate reader will be able to follow without sacrificing detailed and up-to-date coverage ofthe major developments. Uses an interdisciplinary approach including behavioral and neurophysiological data Describes a variety of experimental methodologies Treats neural computations necessary for the control of movement Covers implications of biomechanics for control, sensory mechanisms, and perceptual processing (haptics) Includes manipulative hand function as well as reaching Overviews each group of chapters using link sections Contains an integrated index and a glosssary The five sections cover: Mediating variables in perception and prehension The coordination of muscles with the central nervous system The nature of movement control and hand positioning Hand-arm coordination in reaching and grasping The sensory function of the hand

Book Description
Despite the intensive experimental and theoretical studies for over a century, the general processes involved in neural control of pasture and movement, in learning of motor behaviour in healthy subjects and in adaptation in pathology were and remain a challenging problems for the scientists in the field of sensorimotor control. The book is the outcome of the Advanced Research Workshop Sensorimotor Control, where the focus was on the state and the perspectives of the study in the field.

Book Description
Dexterous manipulation is a representative task that involves sensorimotor integration underlying a fine control of movements. Over the past 30 years, research has provided significant insight, including the control mechanisms of force coordination during manipulation tasks. Successful dexterous manipulation is thought to rely on the ability to integrate the sense of digit position with motor commands responsible for generating digit forces and placement. However, the mechanisms underlying the phenomenon of digit position-force coordination are not well understood. This dissertation addresses this question through three experiments that are based on psychophysics and object lifting tasks. It was found in psychophysics tasks that sensed relative digit position was accurately reproduced when sensorimotor transformations occurred with larger vertical fingertip separations, within the same hand, and at the same hand posture. The results from a follow-up experiment conducted in the same digit position-matching task while generating forces in different directions reveal a biased relative digit position toward the direction of force production. Specifically, subjects reproduced the thumb CoP higher than the index finger CoP when vertical digit forces were directed upward and downward, respectively, and vice versa. It was also found in lifting tasks that the ability to discriminate the relative digit position prior to lifting an object and modulate digit forces to minimize object roll as a function of digit position are robust regardless of whether motor commands for positioning the digits on the object are involved. These results indicate that the erroneous sensorimotor transformations of relative digit position reported here must be compensated during dexterous manipulation by other mechanisms, e.g., visual feedback of fingertip position. Furthermore, predicted sensory consequences derived from the efference copy of voluntary motor commands to generate vertical digit forces may override haptic sensory feedback for the estimation of relative digit position. Lastly, the sensorimotor transformations from haptic feedback to digit force modulation to position appear to be facilitated by motor commands for active digit placement in manipulation.

Book Description
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.

Book Description
During the last three decades, many laboratories worldwide have dedicated their research activities to understanding the roles of the cerebellum in motor control, cognitive processes and the biology of mental processes, behavioral symptoms and emotion. These advances have been associated with discoveries of new clinical disorders, in particular in the field of genetic ataxias, and the growing number of diseases presents a source of difficulty for clinicians during daily practice. This practical guide summarizes and evaluates current knowledge in the field of cerebellar disorders. Encompassing details of both common and uncommon cerebellar ataxias, including vascular, immune, neoplastic, infectious, traumatic, toxic and inherited disorders, this book will assist clinicians in the diagnosis and management of the full spectrum of cerebellar ataxias encountered in daily practice. Essential reading for clinicians, including general practitioners, neurologists, pediatricians, radiologists, psychiatrists and neuropsychologists, this will also prove a valuable tool for students, trainees and researchers.

Book Description
Reaching for objects in our surroundings is an everyday activity that most humans perform seamlessly a hundred times a day. It is nonetheless a complex behavior that requires the perception of objects’ features, action selection, movement planning, multi-joint coordination, force regulation, and the integration of all of these properties during the actions themselves to meet the successful demands of extremely varied task goals. Even though reach-to-grasp behavior has been studied for decades, it has, in recent years, become a particularly growing area of multidisciplinary research because of its crucial role in activities of daily living and broad range of applications to other fields, including physical rehabilitation, prosthetics, and robotics. This volume brings together novel and exciting research that sheds light into the complex sensory-motor processes involved in the selection and production of reach-to-grasp behaviors. It also offers a unique life-span and multidisciplinary perspective on the development and multiple processes involved in the formation of reach-to-grasp. It covers recent and exciting discoveries from the fields of developmental psychology and learning sciences, neurophysiology and brain sciences, movement sciences, and the dynamic field of developmental robotics, which has become a very active applied field relying on biologically inspired models. This volume is a rich and valuable resource for students and professionals in all of these research fields, as well as cognitive sciences, rehabilitation, and other applied sciences.
