Book excerpt: Smooth pursuit eye movements work in combination with other eye movement systems to ensure stable vision in a non-stationary world. Pursuit eye movements are tracking eye movements that allow primates to keep moving objects stable on the retina for improved visual processing. Although the basic task of the pursuit system is to perform a sensorimotor transformation that generates an eye velocity that matches target velocity, the relationship between target motion and subsequent eye movement is not fixed. This thesis investigates the neural signals that modulate the sensorimotor transformation for pursuit, based both on current context and on previous experience. The amplitude of the pursuit response to a brief perturbation of target velocity is larger if the perturbation is presented during ongoing pursuit vs. during fixation. To understand the neural signals used by the pursuit system to control the gain of the response to target perturbations under different initial conditions and thereby constrain the possible sites and mechanisms of context-dependent pursuit modulation, I used passive whole body rotation to distinguish between eye velocity (eye in head) and gaze velocity (eye in world) signals. Adaptive modification of the vestibulo-ocular reflex allowed a further distinction between gaze velocity per se and the visually-driven component of gaze velocity. The results demonstrate that signals intermediate to gaze velocity and visually-driven gaze velocity control context-dependent modulation of pursuit. In a separate set of experiments, I investigated the signals that modulate the sensorimotor transformation for pursuit based on experience. Specifically, I used microstimulation in cortical area MT to test the hypothesis that visual motion signals represented there could provide instructive signals for pursuit learning. The results demonstrate that activity in MT, consistently associated with pursuit in a given direction, is sufficient to drive learning for pursuit. Additional experiments stabilizing the target on the retina and using motion of a visual background to mimic MT stimulation demonstrate that visual signals in general, including target motion relative to the eye, and activity in MT, are provide powerful instructive signals for pursuit learning under physiological conditions.

John Leigh Professor, Neuroscience Otolaryngology and Biomedical Engineering Case Western Reserve University University Hospitals and Veterans Affairs Medical Center Cleveland Ohio and published by Oxford University Press, USA. This book was released on 1999-08-26 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neurology of Eye Movements provides clinicians with a synthesis of current scientific information that can be applied to the diagnosis and treatment of disorders of ocular motility. Basic scientists will also benefit from descriptions of how data from anatomical, electrophysiological, pharmacological, and imaging studies can be directly applied to the study of disease. By critically reviewing such basic studies, the authors build a conceptual framework that can be applied to the interpretation of abnormal ocular motor behavior at the bedside. These syntheses are summarized in displays, new figures, schematics and tables. Early chapters discuss the visual need and neural basis for each functional class of eye movements. Two large chapters deal with the evaluation of double vision and systematically evaluate how many disorders of the central nervous system affect eye movements. This edition has been extensively rewritten, and contains many new figures and an up-to-date section on the treatment of abnormal eye movements such as nystagmus. A major innovation has been the development of an option to read the book from a compact disc, make use of hypertext links (which bridge basic science to clinical issues), and view the major disorders of eye movements in over 60 video clips. This volume will provide pertinent, up-to-date information to neurologists, neuroscientists, ophthalmologists, visual scientists, otalaryngologists, optometrists, biomedical engineers, and psychologists.

Book excerpt: The philosophy of perception is a microcosm of the metaphysics of mind. Its central problems—What is perception? What is the nature of perceptual consciousness? How can one fit an account of perceptual experience into a broader account of the nature of the mind and the world?—are at the heart of metaphysics. Rather than try to cover all of the many strands in the philosophy of perception, this book focuses on a particular orthodoxy about the nature of visual perception. The central problem for visual science has been to explain how the brain bridges the gap between what is given to the visual system and what is actually experienced by the perceiver. The orthodox view of perception is that it is a process whereby the brain, or a dedicated subsystem of the brain, builds up representations of relevant figures of the environment on the basis of information encoded by the sensory receptors. Most adherents of the orthodox view also believe that for every conscious perceptual state of the subject, there is a particular set of neurons whose activities are sufficient for the occurrence of that state. Some of the essays in this book defend the orthodoxy; most criticize it; and some propose alternatives to it. Many of the essays are classics. Contributors G.E.M.

Book excerpt: An examination of the link between the vigor with which we move and the value that the brain assigns to the goal of the movement. Why do we reflexively run toward people we love, but only walk toward others? In Vigor, Reza Shadmehr and Alaa Ahmed examine the link between how the brain assigns value to things and how it controls our movements. They find that brain regions thought to be principally involved in decision making also affect movement vigor--and that brain regions thought to be principally responsible for movement also bias patterns of decision making.

Book excerpt: Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world.

Book excerpt: Recent physiologic investigations have shown that the deep cerebellar nuclei may play an important role in the initiation and monitoring of skilled move ments. Much of this physiologic work has been carried out in the absence of a secure foundation in neuroanatomical information. Although the main sources of the afferent fibers and the major terminations of the efferent fibers related to these nuclei have been known for many years, remarkably little information about the organization of the nuclei themselves has been collected. The kinds of nerve cells, their arrangement within the nuclei, the patterns of their dendritic arborizations, the distribution of incoming fibers among the neurons, the relationship between the outgoing nerve fibers and the nerve cells from which they originate - these and many other morphologic features were either unknown or only superficially explored. In fact, so little was known about the deep cerebellar nuclei when I began to work on this subject that the investigations reported here are virtually without antecedents, a refreshing change from the cerebellar cortex which has been repeatedly and exhaustively surveyed. My studies on the cerebellar nuclei began in the spring of 1972. They were initiated with the intent of applying the principles of analysis that had been developed for the cerebellar cortex to a different but related part of the brain.

Book excerpt: The first comprehensive treatment of active inference, an integrative perspective on brain, cognition, and behavior used across multiple disciplines. Active inference is a way of understanding sentient behavior—a theory that characterizes perception, planning, and action in terms of probabilistic inference. Developed by theoretical neuroscientist Karl Friston over years of groundbreaking research, active inference provides an integrated perspective on brain, cognition, and behavior that is increasingly used across multiple disciplines including neuroscience, psychology, and philosophy. Active inference puts the action into perception. This book offers the first comprehensive treatment of active inference, covering theory, applications, and cognitive domains. Active inference is a “first principles” approach to understanding behavior and the brain, framed in terms of a single imperative to minimize free energy. The book emphasizes the implications of the free energy principle for understanding how the brain works. It first introduces active inference both conceptually and formally, contextualizing it within current theories of cognition. It then provides specific examples of computational models that use active inference to explain such cognitive phenomena as perception, attention, memory, and planning.

Available in PDF, EPUB and Kindle. Book excerpt: Saccadic eye movements shift the direction of the eye rapidly from one part of the visual field to another. The system within the brain controlling this eye movement is probably the best understood sensory motor system in the brain of primates. The Neurobiology of Saccadic Eye Movements presents a series of state-of-the-art reviews of this system including the behavior, neuronal mechanisms, and systems engineering characterization. The successful interaction of systems modelling with the neurophysiological approaches described in this book provide a potential blueprint for future study of more complicated systems within the brain.
