Book Synopsis Visual Motion and Its Role in the Stabilization of Gaze by : Frederick Albert Miles
Download or read book Visual Motion and Its Role in the Stabilization of Gaze written by Frederick Albert Miles and published by Elsevier Science & Technology. This book was released on 1993 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. This fifth volume of Reviews of Oculomotor Research is mainly concerned with the visual stabilization mechanisms but, unlike the previous volumes in the series, the coverage goes beyond the mammalian literature. The emphasis is on the visual processing problems that must be solved if the motor responses are to be appropriate. Chapters are included dealing specifically with the psychophysics and physiology of visual motion, areas of intense research activity in recent years.The first section deals with the fundamental problem of how motion is first decoded by the visual system. The second section deals with more global aspects of the visual motion experienced by the moving observer. The third and last section deals with specific stabilizing behaviors and their underlying physiology.An excellent book, at the cutting edge of research developments in visual stabilization mechanisms.
Book Synopsis Emergent Techniques for Assessment of Visual Performance by : National Research Council
Download or read book Emergent Techniques for Assessment of Visual Performance written by National Research Council and published by National Academies Press. This book was released on 1985-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.

Book Synopsis Context- and Experience-dependent Modulation of the Sensorimotor Transformation for Smooth Pursuit Eye Movements by : Megan Rose Carey
Download or read book Context- and Experience-dependent Modulation of the Sensorimotor Transformation for Smooth Pursuit Eye Movements written by Megan Rose Carey and published by . This book was released on 2005 with total page 328 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Multisensory Control of Posture by : F. Hlavacka
Download or read book Multisensory Control of Posture written by F. Hlavacka and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: From recent developments in the rapidly growing area of neuroscience it has become increasingly clear that a simplistic description of brain function as a broad collection of simple input-output relations is quite inadequate. Introspection already tells us that our motor behavior is guided by a complex interplay between many inputs from the outside world and from our internal "milieu," internal models of ourselves and the outside world, memory content, directed attention, volition, and so forth. Also, our motor activity normally involves more than a circumscribed group of muscles, even if we intend to move only one effector organ. For example, a reaching movement or a reorientation of a sensory organ almost invariably requires a pattern of preparatory or assisting activities in other parts of the body, like the ones that maintain the body's equilibrium. The present volume is a summary of the papers presented at the symposium "Sensory Interaction in Posture and Movement Control" that was held at Smolenice Castle near Bratislava, Slovakia, as a Satellite Symposium to the ENA Meeting 1994 in Vienna. The focus of this meeting was not only restricted to the "classical" sensory interactions such as between vestibular and visual signals, or between otolith and semicircular canal inputs. Rather, the symposium tried to consider also the interplay between perception and action, between reflexive and volitional motor acts as well as between sensory driven or self-initi ated motor acts and reafferent inputs.

Book Synopsis Biocybernetics Of Vision: Integrative Mechanisms And Cognitive Processes by : Cloe Taddei-ferretti
Download or read book Biocybernetics Of Vision: Integrative Mechanisms And Cognitive Processes written by Cloe Taddei-ferretti and published by World Scientific. This book was released on 1998-01-15 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual cognition is an important area of biocybernetics. It ranges from the filtering processes of early vision to the structural and functional organization of the visual centres, as well as, in higher animals, to the neuronal plasticity, the decision-making rules, the effect of noise, the role of attention, the ambiguity of patterns, and the time dimension. All these factors contribute to the cognitive interpretation of visual sensation that takes place in visual perception. A side field is machine vision, in which the signal processing known from animal vision is applied to the mobile robots responding to light stimulation.
Book Synopsis Dynamics of Visual Motion Processing by : Guillaume S. Masson
Download or read book Dynamics of Visual Motion Processing written by Guillaume S. Masson and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion processing is an essential piece of the complex brain machinery that allows us to reconstruct the 3D layout of objects in the environment, to break camouflage, to perform scene segmentation, to estimate the ego movement, and to control our action. Although motion perception and its neural basis have been a topic of intensive research and modeling the last two decades, recent experimental evidences have stressed the dynamical aspects of motion integration and segmentation. This book presents the most recent approaches that have changed our view of biological motion processing. These new experimental evidences call for new models emphasizing the collective dynamics of large population of neurons rather than the properties of separate individual filters. Chapters will stress how the dynamics of motion processing can be used as a general approach to understand the brain dynamics itself.
Book Synopsis The Oxford Handbook of Eye Movements by : Simon Liversedge
Download or read book The Oxford Handbook of Eye Movements written by Simon Liversedge and published by OUP Oxford. This book was released on 2011-08-18 with total page 1048 pages. Available in PDF, EPUB and Kindle. 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.
