Book Synopsis The Neural Basis of Early Vision by : A. Kaneko
Download or read book The Neural Basis of Early Vision written by A. Kaneko and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers in recent decades have elucidated signal transduction in the retina and the function of the visual cortex. The highly flexible nature of neural circuits in the visual cortex especially during the critical period has been an interesting subject for studying neural plasticity and development. Recent advances in the visual neurosciences of the vertebrate retina and the visual cortex were discussed during the 12th Keio International Symposium for Life Science and Medicine, meeting jointly with Vision Forum 2002. Contributions to the symposium collected in this volume reflect the convergence of physiological, cell biological, molecular, mathematical, and clinical approaches. The book covers topics ranging from phototransduction to visual information processing in the primary visual cortex, and includes clinical studies on hereditary night blindness, creating a valuable source of information for researchers and clinicians in the visual neurosciences.

Available in PDF, EPUB and Kindle. Book excerpt: In the mid-sixties, John Robson and Christina Enroth-Cugell, without realizing what they were doing, set off a virtual revolution in the study of the visual system. They were trying to apply the methods of linear systems analysis (which were already being used to describe the optics of the eye and the psychophysical performance of the human visual system) to the properties of retinal ganglion cells in the cat. Their idea was to stimulate the retina with patterns of stripes and to look at the way that the signals from the center and the antagonistic surround of the respective field of each ganglion cell (first described by Stephen Kuffier) interact to generate the cell's responses. Many of the ganglion cells behaved themselves very nicely and John and Christina got into the habit (they now say) of calling them I (interesting) cells. However. to their annoyance, the majority of neurons they recorded had nasty, nonlinear properties that couldn't be predicted on the basis of simple summ4tion of light within the center and the surround. These uncoop erative ganglion cells, which Enroth-Cugell and Robson at first called D (dull) cells, produced transient bursts of impulses every time the distribution of light falling on the receptive field was changed, even if the total light flux was unaltered.

Book Synopsis Longitudinal Effects of an Optic Nerve Injury on Visual Behaviour by : Jacqueline L. Higgins

Available in PDF, EPUB and Kindle. Book excerpt: Disease or trauma to the visual system can cause long-term damage and severe visual deficits. However, recent research has turned to neural plasticity as a means to recover functional vision despite anatomical damage. To understand the involvement of neural plasticity and reorganization following a deficit, the present thesis investigated the spontaneous recovery of visual functions over time using behavioural tests in mice. Specifically, a partial optic nerve crush (pONC) was induced with two injury intensities, while still allowing for residual vision from surviving retinal cells. Behavioural assessments of visual functions included the optomotor reflex test, which measured the mouse's tracking reflex in response to moving sinusoidal gratings, while the visual cliff test evaluated depth avoidance behaviour by simulating a cliff to observe the animal's perception of depth. The tests were performed once before the injury, then at multiple time points up to 28 days. Retinal ganglion cell survival was subsequently quantified. Results showed that the high-intensity pONC led to a complete loss of visual acuity and depth avoidance, with no improvement in the following 28 days, whereas the low-intensity pONC showed a partial recovery. There were fewer surviving cells after the high-intensity pONC, especially in proximal regions. These results show evidence of spontaneous recovery of visual functions, but only with a certain amount of cell survival.

Book Synopsis Reprogramming the Cerebral Cortex by : Stephen G. Lomber
Download or read book Reprogramming the Cerebral Cortex written by Stephen G. Lomber and published by Oxford University Press. This book was released on 2006-10-12 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain has a remarkable ability to adapt in the event of damage - in many cases shifting responsibility for specific cognitive functions to other non-damaged brain regions. This 'plasticity' can be crucial in aiding recovery from stroke, trauma, and peripheral damage such as eye or ear damage. Over the past thirty years our view of cortical plasticity has evolved greatly. Early studies suggested that changes to cortical function due to peripheral lesions could only occur duringdevelopment and that these plastic changes were specific to a particular temporal window or "critical period". Over time, it has been demonstrated that cortical modifications as a consequence of either peripheral or central lesions can induce adaptive, or beneficial, changes in cortical function in aneffort to preserve or enhance function. More recently, studies have identified that many of these adaptive changes, once thought only possible in the developing brain, are also possible in the mature or developed brain. At present, many laboratories are defining the beneficial capabilities of cerebral cortex plasticity, upon which many proactive and therapeutic strategies may be developed in order to maximiSe the "reprogramming" capabilities of the cerebrum.'Reprogramming the Cerebral Cortex' describes these exciting studies and examines adaptive cortical plasticity in a variety of systems (visual, auditory, somatomotor, cross-modal, language and cognition). The book leads the reader through the complexities and promise of neuroplasticity, and presents insights into current and future research and clinical practice. It is unique in looking at the beneficial capabilities of cerebral cortex plasticity, upon which many proactive and therapeuticstrategies may be developed.The book will be a valuable resource for behavioural, systems, computational and cognitive neuroscientists, as well as clinicians and neuropsychologists.
Book Synopsis Pediatric Neuro-Ophthalmology by : Michael C. Brodsky
Download or read book Pediatric Neuro-Ophthalmology written by Michael C. Brodsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pediatric Neuroophthalmology details the diagnostic criteria, current concepts of pathogenesis, neuroradiological correlates, and clinical management of a large group of neuroophthalmic disorders that present in childhood. Surprisingly distinct from neuroophthalmic disorders afflicting adults, this set of diseases falls between the cracks of most ophthalmology training, and thus, warrants a practical, clinical guide for the practitioner in ophthalmology - the neuroophthalmologist, pediatric ophthalmologist, general ophthalmologist - as well as neurologists and for residents. The authors, leading pediatric ophthalmologists, have taken this difficult subject matter and developed an accessible, user-friendly manual with a detailed approach to the recognition, differential diagnosis, and management of pediatric neuroophthalmologic disorders.
Book Synopsis Vision: From Neurons to Cognition by : C. Casanova
Download or read book Vision: From Neurons to Cognition written by C. Casanova and published by Gulf Professional Publishing. This book was released on 2001-10-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internationally renowned researchers discuss how the various parts of the brain process and integrate visual signals, providing up to date original findings, reviews, and theoretical proposals on visual processing. This book addresses the basic mechanisms of visual perception as well as issues such as neuronal plasticity, functional reorganization and recovery, residual vision, and sensory substitution. Knowledge of the basic mechanisms by which our brain can analyze, reconstruct, and interpret images in the external world is of fundamental importance for our capacity to understand the nature and causes of visual deficits, such as those resulting from ischemia, abnormal development, neuro-degenerative disorders, and normal aging. It is also essential to our goal of developing better therapeutic strategies, such as early diagnosis, visual training, behavioral rehabilitation of visual functions, and visual implants.
