Susan Barry - Böcker

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, Barry's 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 brain's capacity for change, Fixing My Gaze describes Barry's remarkable journey and celebrates the joyous pleasure of our senses.

Doctors have been able to cure some forms of congenital blindness and deafness for decades. But this has created another problem: most people end up hating their new senses. To ask someone to adapt to a new sense is to ask them to reshape their entire world. Many simply cannot. Every waking minute, they are bombarded by meaningless sights or sounds. Some sink into a depression so great that they lose their will to live and die.So then what to do with the cases of Liam McCoy and Zora Damji? Liam was born blind and Zora was born deaf. Both received surgeries to restore their senses as teenagers. Today, both lead healthy, independent lives. The question at the heart of Coming to Our Senses is: why? The answer reveals a common misunderstanding of how perception works. We tend to think of perception as a purely mechanical process, as a camera or microphone in the brain, recording the world objectively. But neurobiologist Susan Barry argues that your senses are completely your own. What you hear or see is influenced by your environment, history, age, relationships, preferences, fears, and needs. Your senses are so intimately connected to your experiences that they actually shape your personality. And as you grow, your senses grow with you, much further into adulthood than doctors once thought. The way you sense the world is part of what makes you, you.People like Liam and Zohra provide a clear view of how our sensory abilities intertwine with our personality, and Barry spent a decade with them, watching their process. Barry finds the environmental sources of Liam's exquisite sense of direction, as well his inability to learn to recognize even his own mother's face. And she considers how Zohra's world expands upon learning that sound allows you to observe things you can't see, as well as how the voice of Zohra's Aunt Najma influenced the kinds of voices Zohra can understand best. Ultimately, Liam and Zohra adapted to their new senses because their individual circumstances allowed them to do so, and in ways that reflect those circumstances. But there is no single answer to why some people adapt to their new senses while others do not, or for that matter, why two normally sighted people can see the same thing two different ways -- the answer depends upon the whole history and tenor of a person's life.Coming to Our Senses tells its stories with grace, empathy, and genuine curiosity. It is a testament to the power of resilience, and a moving account of how, regardless of how we're born, we must each find our own way.
