Book Description
Retinal Computation summarizes current progress in defining the computations performed by the retina, also including the synaptic and circuit mechanisms by which they are implemented. Each chapter focuses on a single retinal computation that includes the definition of the computation and its neuroethological purpose, along with the available information on its known and unknown neuronal mechanisms. All chapters contain end-of-chapter questions associated with a landmark paper, as well as programming exercises. This book is written for advanced graduate students, researchers and ophthalmologists interested in vision science or computational neuroscience of sensory systems. While the typical textbook's description of the retina is akin to a biological video camera, the real retina is actually the world's most complex image processing machine. As part of the central nervous system, the retina converts patterns of light at the input into a rich palette of representations at the output. The parallel streams of information in the optic nerve encode features like color, contrast, orientation of edges, and direction of motion. Image processing in the retina is undeniably complex, but as one of the most accessible parts of the central nervous system, the tools to study retinal circuits with unprecedented precision are up to the task. This book provides a practical guide and resource about the current state of the field of retinal computation. - Provides a practical guide on the field of retinal computation - Summarizes and clearly explains important topics such as luminance, contrast, spatial features, motion and other computations - Contains discussion questions, a landmark paper, and programming exercises within each chapter

Editorial Reviews: ".this book is also a unique overview of our current understanding of the why and the how of retinal computation and there is something here for anyone with a grounding in vision science who recognises that there is more to what the retina does than. meets the eye." -- Prof Steven Dakin, New Zealand Optics, May 28, 2022. "I want to commend Dr. Schwartz for assembling this incredible resource and strongly recommend Retinal Computation to everyone who is a student of vision. The vast majority of modern topics in retina are covered yet in a fashion that is clear, and concise. The book covers the cellular and circuit basis of computations ranging from those covered by most textbooks, such as center-surround receptive field or direction selectivity , to those you probably do not associated with the retina such as "motion anticipation" and "threat detection". Each chapter is self-contained, meaning you can easily "pick and choose" the topics. A quick perusal of the chapter titles are almost certainly going to pique your interest. For example, you may know that the retina has single photon sensitivity but do you know "How many photons does it take to create a percept"? (Chapter 1). How does the retina encode texture (i.e. spatial fluctuations within the receptive field)? (Chapter 7). Is object motion sensitivity related to Direction selectivity? (Chapter 12). The list goes on. This book will also serve as a great resource for those teaching advanced undergraduate or graduate level vision courses for students with backgrounds in experimental or computational vision science. Each chapter contains what Dr. Schwartz's considers a "landmark paper" in the field, with a set of questions that can be used as a guide for reading these papers. And finally he includes programming exercises that can be easily implemented in Matlab to address basic concepts introduced in the chapter. The instructions are detailed so that even those new to Matlab will be able to implement these exercises these straightforward. It is this combination - textbook chapter + primary literature + quantitative exercises that will solidify these concepts. There are many vision science topics not covered in the book. For example, there is little on retinal disease or development. But these limitations are far outweighed by where the book succeeds. The vast majority of the book is written by Dr. Schwartz, giving it a uniformity that is welcome. Despite tackling quite modern questions where there is ongoing progress, Dr.Schwartz has extracted what are key findings that are likely to stand the test of time. And finally, it is really interesting! For those who think that the retina is "solved", think again. Retinal computations is a fantastic way for all circuit neuroscientist to learn how much computations can be achieved with very few synapses." -- Marla B. Feller, Ph. D., Paul Licht Distinguished Professor in Biological Sciences, Division of Neurobiology, Department of Molecular and Cell Biology & Helen Wills Neuroscience Institute University of California, Berkeley "This fantastic new textbook from a rising star in the field clearly and thoroughly updates our picture of what the retina computes. It is detailed enough for senior researchers but also pedagogical, providing a go-to reference for students. The illustrations within the text and for the chapter headings are both beautiful and informative." -- Stephanie E. Palmer, Ph.D., Associate Professor, Department of Organismal Biology and Anatomy, Department of Physics, University of Chicago "This book summarizes the impressive recent progress in understanding how visual computations are performed by retinal circuits. The book is an important resource not only for retinal experts, but more generally for anyone seeking to explain how the brain works at the level of neural circuits. Greg Schwartz and his co-authors have made a major contribution to the field." -- Sebastian Seung, Anthony B. Evnin '62 Professor, Neuroscience Institute and Computer Science Dept., Princeton University "This is a wonderful book from a true expert in the retina field. It is a fantastic resource for researchers, lecturers, and students alike. The book nicely covers the many facets of how the retina processes the visual input that enters the eye. Despite the richness in material, the presentation manages to stay accessible and always connects back to fundamental questions of visual processing. Each chapter by itself is a great entry point into a particular area of how the neural network of the retina deals with a specific set of visual challenges. I have thoroughly enjoyed this wonderful overview of retinal computation, served on a silver platter, and I will use the book both as background material for research and as a resource for teaching. I particularly like the sets of exercises that conclude each chapter." -- Dr. Tim Gollisch, Professor for Sensory Processing in the Retina, Department of Ophthalmology, University Medical Center Göttingen

Book Description
Neural computation arises from the capacity of nervous tissue to process information and accumulate knowledge in an intelligent manner. Conventional computational machines have encountered enormous difficulties in duplicatingsuch functionalities. This has given rise to the development of Artificial Neural Networks where computation is distributed over a great number of local processing elements with a high degree of connectivityand in which external programming is replaced with supervised and unsupervised learning. The papers presented in this volume are carefully reviewed versions of the talks delivered at the International Workshop on Artificial Neural Networks (IWANN '93) organized by the Universities of Catalonia and the Spanish Open University at Madrid and held at Barcelona, Spain, in June 1993. The 111 papers are organized in seven sections: biological perspectives, mathematical models, learning, self-organizing networks, neural software, hardware implementation, and applications (in five subsections: signal processing and pattern recognition, communications, artificial vision, control and robotics, and other applications).

Book Description
Computational neuroscience is best defined by its focus on understanding the nervous systems as a computational device rather than by a particular experimental technique. Accordinlgy, while the majority of the papers in this book describe analysis and modeling efforts, other papers describe the results of new biological experiments explicitly placed in the context of computational issues. The distribution of subjects in Computation and Neural Systems reflects the current state of the field. In addition to the scientific results presented here, numerous papers also describe the ongoing technical developments that are critical for the continued growth of computational neuroscience. Computation and Neural Systems includes papers presented at the First Annual Computation and Neural Systems meeting held in San Francisco, CA, July 26--29, 1992.

Book Description
Neuronal dendritic trees are complex structures that endow the cell with powerful computing capabilities and allow for high neural interconnectivity. Studying the function of dendritic structures has a long tradition in theoretical neuroscience, starting with the pioneering work by Wilfrid Rall in the 1950s. Recent advances in experimental techniques allow us to study dendrites with a new perspective and in greater detail. The goal of this volume is to provide a résumé of the state-of-the-art in experimental, computational, and mathematical investigations into the functions of dendrites in a variety of neural systems. The book first looks at morphological properties of dendrites and summarizes the approaches to measure dendrite morphology quantitatively and to actually generate synthetic dendrite morphologies in computer models. This morphological characterization ranges from the study of fractal principles to describe dendrite topologies, to the consequences of optimization principles for dendrite shape. Individual approaches are collected to study the aspects of dendrite shape that relate directly to underlying circuit constraints and computation. The second main theme focuses on how dendrites contribute to the computations that neurons perform. What role do dendritic morphology and the distributions of synapses and membrane properties over the dendritic tree have in determining the output of a neuron in response to its input? A wide range of studies is brought together, with topics ranging from general to system-specific phenomena—some having a strong experimental component, and others being fully theoretical. The studies come from many different neural systems and animal species ranging from invertebrates to mammals. With this broad focus, an overview is given of the diversity of mechanisms that dendrites can employ to shape neural computations.
