Book Description
In this book the authors relate and discuss the idea that perceptual processes can be considered at many levels. A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level. For example "induced motion" can be analyzed in terms of eye movements or at the retinal level or at a much higher cognitive level: how do these analyses fit together? The concept of levels also makes us think of the flow of information between levels, which leads to a consideration of the roles of top-down and bottom-up (or feed-forward, feed-back) flow. There are sections devoted to vestibular processing, eye movement processing and processing during brightness perception. The final section covers levels of processing in spatial vision. All scientists and graduate students working in vision will be interested in this book as well as people involved in using visual processes in computer animations, display design or the sensory systems of machines.

Book Description
Synesthesia is a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. In one common form of synesthesia for instance letters or numbers are perceived as inherently colored. People who report a lifelong history of such experiences are known as synesthetes. 00'Layers of Reality' is both a personal and a semi-scientific research into synesthesia. Anna Püschel, a synesthete herself, experiences colours when looking at images. With this research she questions her conception of reality. Using a large database of images she investigates the origin, consistency and subjectivity of her synesthesia, in an attempt to answer the question: "Am I mad?"

Book Description
Perceptual processes can be approached experimentally and conceptually at many levels: A phenomenon that appears at one level may not be the same as a superficially similar phenomenon that appears at a different level. Levels of Perception reviews the importance of considering perception as a multilevel process. This book includes sections on brightness and light, eye movements and perception, and perception of orientation and self-motion. The accompanying CD-ROM contains exciting color imageries and video clips associated with various chapters. All neuroscientists, physiologists, and graduate students working in vision, as well as those involved in using visual processes in computer animations, display design, or the sensory systems of machines, will find Levels of Perception invaluable.

Book Description
The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

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.
