Current Oculomotor Research by Wolfgang Becker,Heiner Deubel,Thomas Mergner Pdf

This volume contains the proceedings of the Ninth European Conference on Eye Movements (ECEM 9), held in Ulm, Germany, on September 23-26, 1997. ECEM 9 con tinued a series of conferences initiated by Rudolf Groner of Bern, Switzerland, in 1981 which, from its very beginning, has brought together scientists from very diverse fields with a common interest in eye movements. About 40 of the papers presented at ECEM 9 have been selected for presentation in full length while others are rendered in condensed form. There is a broad spectrum of motives why people have become involved in, and fas cinated by, eye movement research. Neuroscientists have been allured by the prospect of understanding anatomical findings, single unit recordings, and the sequels of experimental lesions in terms of the clearly defined system requirements and the well documented be havioural repertoire of the oculomotor system. Others have been attracted by the richness of this repertoire and its dependence on an intricate hierarchy of factors spanning from "simple" reflexes to visual pattern recognition and spatio-temporal prediction. Neurolo gists, neuro-ophthalmologists and neuro-otologists have long standing experience with eye movements as sensitive indicators of lesions in the brain stem, the midbrain, and the cere bellum. By studying oculomotor malfunctions they have made, and are continuing to make, important contributions to our understanding of oculomotor functions.

The Neurobiology of Saccadic Eye Movements by Robert H. Wurtz,Michael E. Goldberg Pdf

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.

Vestibulo-Oculomotor Research in Space by Andrew H. Clarke Pdf

This monograph describes the findings of spaceflight research related to spatial orientation, sensorimotor coordination and mental function. Exposed to the microgravity conditions of spaceflight, the human experiences a variety of physiological and psychological problems, which are presented here. Recent findings of sensory motor research in space are depicted and their benefits for life on earth discussed. The examination of the vestibulo-oculomotor system for example has led to the development of innovative devices for the measurement of three-dimensional eye and head movements. These devices are currently employed in Earthbound applications such as eye laser surgery. The book is written for students and researchers in neurosciences, biomedical engineering, for neurologists and psychologists as well as for persons wanting to know more about biomedical research in space and its application on earth.

Models of Horizontal Eye Movements by Alireza Ghahari,John D. Enderle Pdf

There are five different types of eye movements: saccades, smooth pursuit, vestibular ocular eye movements, optokinetic eye movements, and vergence eye movements. The purpose of this book series is focused primarily on mathematical models of the horizontal saccadic eye movement system and the smooth pursuit system, rather than on how visual information is processed. In Part 1, early models of saccades and smooth pursuit are presented. A number of oculomotor plant models are described here beginning with the Westheimer model published in 1954, and up through our 1995 model involving a 4th order oculomotor plant model. In Part 2, a 2009 version of a state-of-the-art model is presented for horizontal saccades that is 3rd-order and linear, and controlled by a physiologically based time-optimal neural network. Part 3 describes a model of the saccade system, focusing on the neural network. It presents a neural network model of biophysical neurons in the midbrain for controlling oculomotor muscles during horizontal human saccades. In this book, a multiscale model of the saccade system is presented, focusing on a multiscale neural network and muscle fiber model. Chapter 1 presents a comprehensive model for the control of horizontal saccades using a muscle fiber model for the lateral and medial rectus muscles. The importance of this model is that each muscle fiber has a separate neural input. This model is robust and accounts for the neural activity for both large and small saccades. The muscle fiber model consists of serial sequences of muscle fibers in parallel with other serial sequences of muscle fibers. Each muscle fiber is described by a parallel combination of a linear length tension element, viscous element, and active-state tension generator. Chapter 2 presents a biophysically realistic neural network model in the midbrain to drive a muscle fiber oculomotor plant during horizontal monkey saccades. Neural circuitry, including omnipause neuron, premotor excitatory and inhibitory burst neurons, long lead burst neuron, tonic neuron, interneuron, abducens nucleus, and oculomotor nucleus, is developed to examine saccade dynamics. The time-optimal control mechanism demonstrates how the neural commands are encoded in the downstream saccadic pathway by realization of agonist and antagonist controller models. Consequently, each agonist muscle fiber is stimulated by an agonist neuron, while an antagonist muscle fiber is unstimulated by a pause and step from the antagonist neuron. It is concluded that the neural network is constrained by a minimum duration of the agonist pulse, and that the most dominant factor in determining the saccade magnitude is the number of active neurons for the small saccades. For the large saccades, however, the duration of agonist burst firing significantly affects the control of saccades. The proposed saccadic circuitry establishes a complete model of saccade generation since it not only includes the neural circuits at both the premotor and motor stages of the saccade generator, but it also uses a time-optimal controller to yield the desired saccade magnitude.

Oculomotor Systems and Perception by Sheldon M. Ebenholtz Pdf

Oculomotor systems that regulate eye movements play an important role in accounting for certain qualities of visual experience. They are implicated in a wide array of perceptual topics, from apparent size, depth, and distance, to apparent slant and vertical orientation. This text emphasizes the role of oculomotor systems in perception, and discusses the basic characteristics of such oculomotor systems as those controlling vergence, pursuit, the vestibulo-ocular response, and saccadic eye movements. This volume introduces fundamental concepts in physiological optics, and explores the mechanisms of perception, with a focus on eye movements and the diverse implications of oculomotor research.

Clinical and Basic Oculomotor Research by Stefano Ramat,Dominik Straumann Pdf

This volume provides a snapshot of the state of the art of oculomotor and vestibular research, focusing on the bridge between laboratory and clinical research and the interdisciplinary relationships among ophthalmology, neurology, and otology. A common theme in contemporary neuroscience is how the brain learns and adapts at the most basic levels and how patients can benefit from this type of research. Recent advances in the physiology and anatomy of the eye muscles and other orbital structures and their relevance to strabismus sets the stage in the first section. Then, attention shifts to the vestibular system, beginning with the peripheral applications to clinical neuro-otology, including adaptive control of vestibular reflexes and the implications for programs of physical rehabilitation of patients. Further chapters are directed toward the mechanisms of eye movement control developed specifically in foveate species -- saccades, pursuit, and vergence -- here with an emphasis on applications to clinical neurology and neuro-ophthalmology. Finally, the role of higher-level cerebral processing in the control of eye movements is presented in the framework of state-of-the-art brain imaging and sophisticated behavioral testing paradigms in both humans and experimental animals. The volume provides a critical update from a number of disciplines -- both clinical and basic -- to bring basic physiology to the bedside and vice versa.

Models of the Visual System by George K. Hung,Kenneth J. Ciuffreda Pdf

Over the past thirty years, with improvements in optics, electronics, and computer technology, great strides have been made in the quantitative analysis of the visual system. A number of books on eye movement research have been written that have dealt with specific aspects of either eye movement control. However, none of these books provide a comprehensive overview of multiple aspects of the visual system. Moreover, few of these books contain modeling and detailed quantitative analyses of the visual system. Further, since the major books are almost ten years old, there is a need for an update to include the most recent research findings. It is with these considerations in mind that we have carefully compiled this updated, comprehensive, and quantitative model-based edited book on various components of the visual system. Some of the best vision scientists in the world in their respective fields have contributed to chapters in this book. They have expertise in a wide variety of fields, including bioengineering, basic and clinical visual science, medicine, neurophysiology, optometry, and psychology. Their combined efforts have resulted in a high quality book that covers modeling and quantitative analysis of optical, neurosensory, oculomotor, perceptual and clinical systems. It includes only those techniques and models that have such fundamentally strong physiological, control system, and perceptual bases that they will serve as foundations for models and analysis techniques in the future. The book is aimed first towards seniors and beginning graduate students in biomedical engineering, neurophysiology, optometry, and psychology, who will gain a broad understanding of quantitative analysis of the visual system. In addition, it has sufficient depth in each area to be useful as an updated reference and tutorial for graduate and post-doctoral students, as well as general vision scientists.
