Book Description
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 Description
This is the story of a hugely successful and enjoyable 25-year collaboration between two scientists who set out to learn how the brain deals with the signals it receives from the two eyes. Their work opened up a new area of brain research that led to their receiving the Nobel Prize in 1981. The book contains their major papers from 1959 to 1981, each preceded and followed by comments telling how and why the authors went about the study, how the work was received, and what has happened since. It begins with short autobiographies of both men, and describes the state of the field when they started. It is intended not only for neurobiologists, but for anyone interested in how the brain works-biologists, psychologists, philosophers, physicists, historians of science, and students at all levels from high school to graduate level.

Book Description
Vision and the Visual System offers students, teachers, and researchers a rigorous, yet accessible account of how the brain analyzes the visual scene. Schiller and Tehovnik describe key aspects of visual perception while explaining the relationship between eye movements and the neural structures in the brain, which play a central role in how we process visual information. The book discusses various brain areas involved in processing information, focusing on the evolutionary origins and mechanics behind the several parallel pathways that compose the visual system. Later chapters explain how the nervous system processes the perception of color, motion, depth, and patterns. A variety of illusions are on display in Chapter 14, where the authors provide detailed explanations that deconstruct how the visual system operates to create them. The volume concludes with a discussion of recent attempts to build visual prosthetic devices for blind individuals, of which there are more than 40 million in the world. Vision and the Visual System is based on Professor Schiller's more than 40 years of experience teaching vision courses at MIT, and is tailored especially for college undergraduates and graduate students interested in visual perception and the operations of the visual system. The Dynamic Displays posted here for this book are short video clips that would enhance the reader to understand certain areas of vision. They are particular to the chapter they belong within (9 video clips for Chapter 11, 1 video clip for Chapter 12, and 2 video clips for Chapter 14). http: //web.mit.edu/bcs/schillerlab/book.html

Book Description
People have described nature since the beginning of human history. They do it for various purposes, including to communicate about economic, social, governmental, meteorological, sustainability-related, strategic, military, and survival issues as well as artistic expression. As a part of the whole world of living beings, we use various types of senses, known and unknown, labeled and not identified, to both communicate and create. Describing Nature Through Visual Data is a collection of impactful research that discusses issues related to the visualization of scientific concepts, picturing processes, and products, as well as the role of computing in advancing visual literacy skills. Organized into four sections, the book contains descriptions, theories, and examples of visual and music-based solutions concerning the selected natural or technological events that are shaping present-day reality. The chapters pertain to selected scientific fields, digital art, computer graphics, and new media and confer the possible ways that visuals, visualization, simulation, and interactive knowledge presentation can help us to understand and share the content of scientific thought, research, artistic works, and practice. Featuring coverage on topics that include mathematical thinking, music theory, and visual communication, this reference is ideal for instructors, professionals, researchers, and students keen on comprehending and enhancing the role of knowledge visualization in computing, sciences, design, media communication, film, advertising, and marketing.

Book Description
Because of the ease with which we perceive, many people see perception as something that "just happens." However, even seemingly simple perceptual experiences involve complex underlying mechanisms, which are often hidden from our conscious experience. These mechanisms are being investigated by researchers and theorists in fields such as psychology, cognitive science, neuroscience, computer science, and philosophy. A few examples of the questions posed by these investigations are, What do infants perceive? How does perception develop? What do perceptual disorders reveal about normal functioning? How can information from one sense, such as hearing, be affected by information from another sense, such as vision? How is the information from all of our senses combined to result in our perception of a coherent environment? What are some practical outcomes of basic research in perception? These are just a few of the questions this encyclopedia will consider, as it presents a comprehensive overview of the field of perception for students, researchers, and professionals in psychology, the cognitive sciences, neuroscience, and related medical disciplines such as neurology and ophthalmology.

Book Description
Visual neuroscience is the study of the way in which the -brain accomplishes sight, and this book presents overviews of a range of topics in this area. The chapters are grouped into six sections - retina, retino-geniculate connections, visual development, comparative visual physiology, visual cortex and integrative aspects - and the authors describe both their own contributions to the field, and the influence of their teacher, P.O. Bishop, on their scientific development.
