NATIONAL BESTSELLER • From “the poet laureate of medicine" (The New York Times) and the author of the classic The Man Who Mistook his Wife for a Hat comes a fascinating exploration of the remarkable, unpredictable ways that our brains cope with the loss of sight by finding rich new forms of perception. “Elaborate and gorgeously detailed.... Again and again, Sacks invites readers to imagine their way into minds unlike their own, encouraging a radical form of empathy.” —Los Angeles Times With compassion and insight, Dr. Oliver Sacks again illuminates the mysteries of the brain by introducing us to some remarkable characters, including Pat, who remains a vivacious communicator despite the stroke that deprives her of speech, and Howard, a novelist who loses the ability to read. Sacks investigates those who can see perfectly well but are unable to recognize faces, even those of their own children. He describes totally blind people who navigate by touch and smell; and others who, ironically, become hyper-visual. Finally, he recounts his own battle with an eye tumor and the strange visual symptoms it caused. As he has done in classics like The Man Who Mistook his Wife for a Hat and Awakenings, Dr. Sacks shows us that medicine is both an art and a science, and that our ability to imagine what it is to see with another person's mind is what makes us truly human.

The book provides a comprehensive state-of-the-art overview of current research on cognitive and applied aspects of eye movements. The contents include peer-reviewed chapters based on a selection of papers presented at the 11th European Conference on Eye Movements (Turku, Finland 2001), supplemented by invited contributions. The ECEM conference series brings together researchers from various disciplines with an interest to use eye-tracking to study perceptual and higher order cognitive functions. The contents of the book faithfully reflect the scope and diversity of interest in eye-tracking as a fruitful tool both in basic and applied research. It consists of five sections: visual information processing and saccadic eye movements; empirical studies of reading and language production; computational models of eye movements in reading; eye-tracking as a tool to study human-computer interaction; and eye movement applications in media and communication research. Each section is concluded by a commentary chapter by one of the leading authorities in the field. These commentaries discuss and integrate the contributions in the section and provide an expert view on the most significant present and future developments in the respective areas. The book is a reference volume including a large body of new empirical work but also principal theoretical viewpoints of leading research groups in the field.

One of the most persistent controversies of modern science has dealt with human visual perception. It erupted in Germany during the 1860s as a dispute between physiologists Hermann von Helmholtz, Ewald Hering, and their schools. Well into the twentieth century these groups warred over the origins of our capacity to perceive space, over the retinal mechanisms that mediate color sensations, and over the role of mind, experience, and inference in vision. Here R. Steven Turner explores the impassioned exchanges of those rival schools, both to illuminate the clash of theory and to explore the larger role of controversy in the development of science. Controversy, he suggests, is constitutive of scientific change, and he uses the Helmholtz-Hering dispute to illustrate how polemics and tacit negotiation shape evolving theoretical stances. Turner focuses on the arguments and issues of the dispute, issues that ranged from the interpretation of color blindness and optical illusions to the therapeutic practices of clinical ophthalmology. As well, he focuses on the personalities, institutions, disciplinary structures, and methodological commitments that shaped the dispute, including the schools' rhetorical strategies. He explores the incommensurability of the protagonists' viewpoints and examines the reception of the theories and the changing fortunes of the schools. Finally, Turner traces the controversy into the twentieth century, where the issues continue to inform the study of vision today. Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

What goes on in human beings when they make or listen to music? What is it about music, what gives it such peculiar power over us, power delectable and beneficent for the most part, but also capable of uncontrollable and sometimes destructive force? Music has no concepts, it lacks images; it has no power of representation, it has no relation to the world. And yet it is evident in all of us–we tap our feet, we keep time, hum, sing, conduct music, mirror the melodic contours and feelings of what we hear in our movements and expressions. In this book, Oliver Sacks explores the power music wields over us–a power that sometimes we control and at other times don’t. He explores, in his inimitable fashion, how it can provide access to otherwise unreachable emotional states, how it can revivify neurological avenues that have been frozen, evoke memories of earlier, lost events or states or bring those with neurological disorders back to a time when the world was much richer. This is a book that explores, like no other, the myriad dimensions of our experience of and with music.

The philosophy of perception is a microcosm of the metaphysics of mind. Its central problems—What is perception? What is the nature of perceptual consciousness? How can one fit an account of perceptual experience into a broader account of the nature of the mind and the world?—are at the heart of metaphysics. Rather than try to cover all of the many strands in the philosophy of perception, this book focuses on a particular orthodoxy about the nature of visual perception. The central problem for visual science has been to explain how the brain bridges the gap between what is given to the visual system and what is actually experienced by the perceiver. The orthodox view of perception is that it is a process whereby the brain, or a dedicated subsystem of the brain, builds up representations of relevant figures of the environment on the basis of information encoded by the sensory receptors. Most adherents of the orthodox view also believe that for every conscious perceptual state of the subject, there is a particular set of neurons whose activities are sufficient for the occurrence of that state. Some of the essays in this book defend the orthodoxy; most criticize it; and some propose alternatives to it. Many of the essays are classics. Contributors G.E.M.
