Book Description
This fourth volume in the Retina Research Foundation Symposia Proceedings highlights several of the strategies and experimental paradigms that are currently used to exploit and amplify the regenerative capacity of the adult mammalian visual system, and reviews the exciting advances being made in understanding the molecular basis of central nervous system regeneration.Because loss of neurons or interruptions of their connective pathways in the mammalian visual system can, in contrast to certain amphibians and fish, lead to permanent loss of vision, studies of regeneration and plasticity in this system serve as valuable models for the reconstitution of other parts of the nervous system and as potential approaches to the diverse disorders that lead to visual loss.Dominic Man-Kit Lam is Director of the Center for Biotechnology and Professor of Biotechnology, Cell Biology, and Ophthalmology at Baylor College of Medicine. Garth M. Bray is Professor in the Centre for Research in Neuroscience at McGill University.Partial Contents and Contributors: I. Introduction. Harold J. Sheedo, James E. Turner. II.

Book Description
Principles of Learning and Memory presents state-of-the-art reviews that cover the experimental analysis of behavior, as well as the biological basis of learning and memory, and that overcome traditional borders separating disciplines. The resulting chapters present and evaluate core findings of human learning and memory that are obtained in different fields of research and on different levels of analysis. The reader will acquire a broad and integrated perspective of human learning and memory based on current approaches in this domain.

Book Description
The best example of filling-in involves the blind spot, a region of the retina devoid of photoreceptors. Remarkably, the region of visual space corresponding to the blind spot is not perceived as a dark region in space, but instead as having the same color and texture as the surrounding background; hence the expression "filling in." While this type of perceptual completion phenomenon is common in the visual domain, it is argued by the leading scientists who contribute to this book that forms of filling-in also take place in other sensory modalities, including the auditory, somatosensory, and motor systems. In a concluding chapter an integrative approach is taken, which attempts to provide a common framework for completion phenomena occurring on a fast time scale, and cortical reorganization in sensory and motor cortex induced by peripheral damage or skill learning taking place on a slower time scale. It is proposed that systematic changes in the interplay between inhibitory and excitatory inputs permit cortical neurons to become driven by new sources of input, which, in addition to initial perceptual consequences can lead to a long-term structural reorganization of cortex. This book represents a truly interdisciplinary approach to neuroscience, with chapters covering computational modeling, visual psychophysics, functional brain imaging, single-cell physiology, and clinical patient cases. It will be of interest to researchers and graduate students in systems neuroscience, cognitive neuroscience, vision science, neuroimaging, perceptual psychology, computational neuroscience, and philosophy of mind.

Book Description
Hebb's postulate provided a crucial framework to understand synaptic alterations underlying learning and memory. Hebb's theory proposed that neurons that fire together, also wire together, which provided the logical framework for the strengthening of synapses. Weakening of synapses was however addressed by "not being strengthened", and it was only later that the active decrease of synaptic strength was introduced through the discovery of long-term depression caused by low frequency stimulation of the presynaptic neuron. In 1994, it was found that the precise relative timing of pre and postynaptic spikes determined not only the magnitude, but also the direction of synaptic alterations when two neurons are active together. Neurons that fire together may therefore not necessarily wire together if the precise timing of the spikes involved are not tighly correlated. In the subsequent 15 years, Spike Timing Dependent Plasticity (STDP) has been found in multiple brain brain regions and in many different species. The size and shape of the time windows in which positive and negative changes can be made vary for different brain regions, but the core principle of spike timing dependent changes remain. A large number of theoretical studies have also been conducted during this period that explore the computational function of this driving principle and STDP algorithms have become the main learning algorithm when modeling neural networks. This Research Topic will bring together all the key experimental and theoretical research on STDP.

Book Description
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 Description
The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements.
