Fixing My Gaze: A Scientist's Journey into Seeing in Three Dimensions - Tapa dura

From the foreword by Oliver Sacks ""Fixing My Gaze" is a beautiful description and appreciation of two very distinct ways of seeing... But it is also an exploration of much more. Sue is at pains not only to present her story, in clear and lucid, often poetic, language, but also, as a scientist, to provide understanding and explanation. She is in a unique position to do this, drawing on both her personal experience and her background as a neurobiologist....Though Sue originally thought her own case unique, she has since found a number of other people with strabismus and related problems who have unexpectedly achieved stereo vision through vision therapy. This is no easy accomplishment. It may require not only optical corrections (proper lenses or prisms, for example), but very intensive training and learning--in effect, learning how to align the eyes and to fuse their images, and unlearning the unconscious habit of suppressing vision which has been occurring perhaps for decades. In this way, vision therapy is directed at the whole person: it requires high motivation and self-awareness, and enormous perseverance, practice and determination, as does psychotherapy, for instance, or learning to play the piano. But it is also highly rewarding, as Sue brings out. And this ability to acquire new perceptual abilities later in life has great implications for anyone interested in neuroscience or rehabilitation, and, of course, for the millions of people who, like Sue, have been strabismic since infancy. Sue's case, and many others, suggest that if there are even small islands of function in the visual cortex, there may be a fair chance of reactivating and expanding them in later life, even after a lapse of decades, if vision can be made optically possible. Cases like these may offer new hope for those once considered incorrigibly stereo-blind. "Fixing My Gaze" will offer inspiration for anyone in this situation, but it is equally a very remarkable exploration of t Temple Grandin, author of "Thinking in Pictures"" "Essential reading for people interested in the brain." ""Eric Kandel, Winner of the Nobel Prize in Physiology/Medicine; author of "In Search of Memory"" """"Fixing My Gaze" is a magical book, at once poetic and scientific, that holds out great hope for all of us. Here Susan Barry recounts her discovery that through training she could acquire, in adulthood, the three dimensional vision she lacked in all her early years. Barry, an excellent brain scientist, illustrates through her personal experiences and the fascinating science of vision that the brain is a marvelously plastic organ that can continue to change its wiring and thereby its function throughout our adult life." """ "David H. Hubel, Winner of the Nobel Prize in Physiology/Medicine; John Franklin Enders Professor of Neurobiology, Emeritus, Harvard Medical School"" """It had been widely thought that an adult, cross-eyed since infancy, could never acquire stereovision, but to everyone's surprise Barry succeeded. In "Fixing My Gaze," she describes how wonderful it was to have, step-by-step, this new 3-D world revealed to her. And as a neurobiologist she is able to discuss the science as an expert, in simple language." "" ""Brock and Fernette Eide, authors of "The Mislabeled Child""" """"Beautifully written, deeply informative, and profoundly inspiring..."Fixing My Gaze "will appeal to anyone interested in the beauty of the nervous system, and should be required reading for every person involved with the education, behavior, and development of children." """ """Michael Chorost, author of "Rebuilt: How Becoming Part Computer Made Me More Human"""" """""Fascinating and moving....Barry shows us that with healthy eyes and the simplest of tools, we can see the world in an entirely new way.

When neuroscientist Susan Barry was fifty years old, she took an unforgettable trip to Manhattan. As she emerged from the dim light of the subway into the sunshine, she saw a view of the city that she had witnessed many times in the past but now saw in an astonishingly new way. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. With each glance, she experienced the deliriously novel sense of immersion in a three dimensional world. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she was seeing Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a critical period in early childhood. According to this theory, Barrys brain had organized itself when she was a baby to avoid double vision and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. A revelatory account of the brains capacity for change, Fixing My Gaze describes Barrys remarkable journey and celebrates the joyous pleasure of our senses.
