Book Description
An investigation of the effects of blindness and other types of visual deficit on cognitive abilities. Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain—as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.

Book Description
In this unique and exhilarating autobiography, Allan Jones – Canada’s first blind diplomat – vividly describes how an untreatable eye disease slowly decimated his visual world, most challengingly during his postings in Tokyo and New Delhi, and how he discovered and took to heart the revelatory Indian philosophy that changed his life. Advaita Vedanta, the most iconoclastic and liberating of the classical Indian philosophies, profoundly altered the author’s experience of self and world. He found that the true self, as distinct from the individual ego, far exceeds the boundaries of individuality. It lies beneath sightedness or blindness and is absolutely unaffected by the latter. This welcome shift of perspective was reinforced by startling discoveries in contemporary physics, evolutionary biology, and developmental psychology that are fully consistent with Advaitic metaphysics. As for the practical applications of metaphysics, this book demonstrates step by step how Advaitic insight and practice significantly reduce physical and psychological tension. The most telling examples have to do with adjustments compelled by extreme circumstances. Thus Jones describes how he drew upon Advaitic mindfulness techniques to maintain his white cane mobility skills in the teeth of permanent spinal, nerve, and muscle pain. The arc of Beyond Vision moves from the claustrophobically personal to the openness of the transpersonal. It begins in a dysfunctional family background, breaking out into a full life encompassing an adventurous foreign service career, spiritual exploration, and an unconventional kind of marital love.

Book Description
Raised in a poverty lifestyle, as a five-year-old boy, I was traumatized due to a life-changing accident. I was later confined to a hospital bed at St. Anthony's Hospital in Amarillo, Texas. I lost half of my eyesight, but that was only the beginning of my challenging experiences. Growing up was a living nightmare as I discovered how lonely life could be. Kids made fun of my appearance. The jokes continued throughout grade school, junior high, and even high school. I had doubts about a lot of things in life until God surprised me with yet another talent, or another person in my life. God put opportunities in front of me. God gave me gifts in the world of sports, which became my counseling during my youth. As a young adult, I faced yet another nightmare. I lost my wife to brain cancer and became a single dad instantly. This was one of the toughest challenges I dealt with. When things happened to me, sometimes it was because of human error, or evil in this world. And yes, sometimes God allowed certain things to happen for His reasons. God was always there to help me overcome and rise above my darkest hours. When I actually started getting to know Jesus Christ, my faith grew and things started turning around for me.

Book Description
In modern day Mexico City, a young graduate student of anthropology, Stefan Marquez Calle, hears a surprising confession from his dying aunt. Her revelation sends him on a journey of discovery that flings him backwards in time to fifteenth century Spain. He finds his own life entangled with that of Alfonso Calle, an ancestor immersed in a quest for religious survival within the intrigue of an underground world. Stefan is drawn into the terrifying realm of the Spanish Inquisition, of brutal torture and burning at the stake of living human beings. In ancient palaces, where King Ferdinand and Queen Isabella rule, black hooded Dominican monks plot murderous schemes in an effort to destroy all vestiges of beleaguered Judaism. Within the same corridors of power, Christopher Columbus, an ambitious explorer, makes harried appeals to the monarchs for help to launch his voyage. How the lives of Stefan and Alfonso, the two central protagonists, are intertwined and the outcome that even today affects many thousands of people, is the essence of this gripping story.

Book Description
Mike May spent his life crashing through. Blinded at age three, he defied expectations by breaking world records in downhill speed skiing, joining the CIA, and becoming a successful inventor, entrepreneur, and family man. He had never yearned for vision. Then, in 1999, a chance encounter brought startling news: a revolutionary stem cell transplant surgery could restore May’s vision. It would allow him to drive, to read, to see his children’s faces. But the procedure was filled with gambles, some of them deadly, others beyond May’s wildest dreams. Beautifully written and thrillingly told, Crashing Through is a journey of suspense, daring, romance, and insight into the mysteries of vision and the brain. Robert Kurson gives us a fascinating account of one man’s choice to explore what it means to see–and to truly live.

Book Description
Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.
