Models of Horizontal Eye Movements Book Excerpt:

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 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. A saccade is a fast eye movement used to acquire a target by placing the image of the target on the fovea. Smooth pursuit is a slow eye movement used to track a target as it moves by keeping the target on the fovea. The vestibular ocular movement is used to keep the eyes on a target during brief head movements. The optokinetic eye movement is a combination of saccadic and slow eye movements that keeps a full-field image stable on the retina during sustained head rotation. Each of these movements is a conjugate eye movement, that is, movements of both eyes together driven by a common neural source. A vergence movement is a non-conjugate eye movement allowing the eyes to track targets as they come closer or farther away. In this book, early models of saccades and smooth pursuit are presented. The smooth pursuit system allows tracking of a slow moving target to maintain its position on the fovea. Models of the smooth pursuit have been developed using systems control theory, all involving a negative feedback control system that includes a time delay, controller and plant in the forward loop, with unity feedback. The oculomotor plant and saccade generator are the basic elements of the saccadic system. The oculomotor plant consists of three muscle pairs and the eyeball. 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. The work presented here is not an exhaustive coverage of the field, but focused on the interests of the author. In Part II, a state-of-art model of the saccade system is presented, including a neural network that controls the system.

The Role of Eye Movements in Perceptual Processes Book Excerpt:

It has become a truism that the frozen optical diagram representation of vision is the worst possible picture of the way in which we visually interact with the environment. Even apart from our reaction to moving targets by pursuit movements, our visual behaviour can be said to be characterised by eye movements. We sample from our environment in a series of relatively brief fixations which move from one point to another in a series of extremely rapid jerks known as saccades. Many questions arising from this characteristic of vision are explored within this volume, including the question of how our visual world maintains its perceptual stability despite the drastic changes in input associated with these eye movements.

Eye Movements Book Excerpt:

The nature, control, and disorders of eye movements are topics which draw together scientists from many diverse fields. On October 29-30, 1976, a Symposium on Eye Movements was held at The University of Texas Health Science Center at San Antonio. The Symposium constituted the Southern Sectional Meeting of the Association for Research in Vision and Ophthalmology. The Program Coordinators, Drs. Frank Bajandas and Barbara Brooks invited an outstanding group of participants to give presentations on a variety of aspects of this subject. This volume contains all of the invited presentations delivered at that meeting. It does not include the excellent free papers, nor the enthusiastic and fruitful discussions that the participants and the audience enjoyed as well. The editorial work for this book was performed by Dr. Brooks and Dr. Bajandas with great care and efficiency. They have made special efforts together with the Publisher, Plenum Press, to bring this information to you in the shortest possible time, so as to retain the currency of its contents. This effort would not have been even considered without the tireless and always dependable assistance of Mrs. Catherine Arocha and Mrs. Louise Whelan. We are also indebted to the ~exas State Commission for the Blind for its help in defraying the expenses ever attendant at significant symposia. George W. Weinstein, M.D.

The Control of Eye Movements Book Excerpt:

The Control of Eye Movements presents the proceedings of the Symposium on the Control of Eye Movements organized by the Smith-Kettlewell Institute of Visual Sciences of the Pacific Medical Center and the Department of Visual Sciences of the University of the Pacific Graduate School of Medical Sciences, San Francisco, California, November 10-11, 1969. The book is organized into two parts. Part I is devoted to presentations of anatomical, physiological, pharmacological, psychological, and clinical aspects of eye movements. The material presented should provide a valuable reference source as well as increase awareness of the need for further investigation of many aspects of the basic physiology of eye movements. Part II presents a series of papers dealing with models of various parts of the oculomotor system. The modeling approach to control of eye movements is still in its infancy and the present work presents the first comprehensive survey of biophysical, mathematical, and engineering aspects of eye movement control.

The Oxford Handbook of Eye Movements Book Excerpt:

In the past few years, there has been an explosion of eye movement research in cognitive science and neuroscience. This has been due to the availability of 'off the shelf' eye trackers, along with software to allow the easy acquisition and analysis of eye movement data. Accompanying this has been a realisation that eye movement data can be informative about many different aspects of perceptual and cognitive processing. Eye movements have been used to examine the visual and cognitive processes underpinning a much broader range of human activities, including, language production, dialogue, human computer interaction, driving behaviour, sporting performance, and emotional states. Finally, in the past thirty years, there have been real advances in our understanding of the neural processes that underpin eye movement behaviour. The Oxford Handbook of Eye Movements provides the first comprehensive review of the entire field of eye movement research. In over fifty chapters, it reviews the developments that have so far taken place, the areas actively being researched, and looks at how the field is likely to devlop in the coming years. The first section considers historical and background material, before moving onto section 2 on the neural basis of eye movements. The third and fourth sections looks at visual cognition and eye movements and eye movement pathology and development. The final sections consider eye movements and reading and language processing and eye movements. Bringing together cutting edge research from and international team of leading psychologists, neuroscientists, and vision researchers, this book is the definitive reference work in this field.

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. In this book, a multiscale model of the saccade system is presented, focusing on the neural network. Chapter 1 summarizes a whole muscle model of the oculomotor plant based on the 2009 3rd-order and linear, and controlled by a physiologically based time-optimal neural network. Chapter 2 presents a neural network model of biophysical neurons in the midbrain for controlling oculomotor muscles during horizontal human saccades. To investigate horizontal saccade dynamics, a 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. A generic neuron model serves as the basis to match the characteristics of each type of neuron in the neural network. We wish to express our thanks to William Pruehsner for drawing many of the illustrations in this book.

Eye Movements in Reading Book Excerpt:

Eye Movements in Reading: Perceptual and Language Processes focuses on eye movement and cognitive processes as a way to study the reading process. This book also discusses the different aspects of reading. Organized into seven parts encompassing 26 chapters, this book begins with a discussion on the perceptual and psychophysical factors essential to eye movement during reading. This book then explains how some psychophysical factors, such as type size and masking, affect the reading performance. Other chapters consider the role of transient and sustained cells, as well as their possible effects on reading. This text also examines the size of the perceptual span in reading and the integration of information across eye movement. Finally, this book explains the eye movement abnormalities, general eye movement parameters, and the cognitive processes within the reading disabled group. This book is a valuable resource to optometrists, scientists, field researchers, and readers who are interested in the reading process.

Eye Movements and Psychological Processes Book Excerpt:

In the 10 years prior to publication the quantity of research on eye movements as they pertain to psychological processes had been increasing at a rapid rate. Originally published in 1976, the editors’ purpose was to bring together investigators representing different theoretical positions and methodological approaches to present their recent findings, to debate the theoretical points of view, and to identify and discuss the major research problems on eye movements at the time. An attempt was made to invite participants ranging all the way from promising graduate students through the established authorities in the field. The result was an intensive three-day session with meetings from early morning until late into the evening with much opportunity for formal and informal group discussion. The edited papers and transcripts of the discussions are the contents of this book.

Eye Movement Disorders Book Excerpt:

There is perhaps no area of neuro-ophthalmology that is advancing more rapidly with respect to an understanding of its anatomy and physiology than the ocular motor system. For this reason, it is difficult not only to keep up with the latest information concerning the basic mechanisms involved in the control of eye movements but also to remain up to date regarding the pathophysiology of specific disorders of eye movement. The material in this book is derived from a two-day course on eye movements held in The Netherlands in 1986. The course was designed as an introduction to the normal ocular motor system and to disorders of eye movements and was aimed toward orthoptists, ophthalmolo gists, optometrists, neurologists, and neurosurgeons. The chapters in this book were compiled by a trio of experts in the field of eye movements and contain discussions of anatomy and physiology of the ocular motor system, techniques of examination of patients with diplopia, and pathophysiology of specific disorders of ocular motility. Many of the authors of these chapters are among the most active investigators of eye movements in the world today, and their comments thus reflect the latest information in the field. This text is both basic and com prehensive and thus has something for everyone, from the student just beginning a study of the ocular motor system to the seasoned 'veteran' who wishes to know the latest information regarding central ocular motor control mechanisms.
