اصلاح نگاه من: سفر یک دانشمند به دنیای دیدن در سه بعد

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 Neuroscientist Tells The Remarkable Story Of How She Rewired Her Own Brain—and Came To See The World Anew

The Barnes & Noble Review

A Neurologist Friend Of Mine Recently Told Me The Following Tale. A Retired Professor Came To His Office And Said, I Think I Have Had A Stroke. My Friend Asked What His Grounds Were For Saying So, And The Professor Replied, I Have Begun To See Phantom Figures Repeatedly Rising Out Of The Floor To My Left. Something Must Have Happened In The Occipital Lobe Of My Brain On The Right Side. Sure Enough, A Scan Revealed A Small Blood Clot In The Very Region Of The Brain That Processes Left Visual Field Information.

The Professor's Phantoms Vanished After A Couple Of Weeks As The Clot Dissipated. It Is Interesting To Speculate What, In An Earlier Age, Such Visions Might Have Prompted: What Cathedrals, What Wars, What Reports From Beyond. But To A Mind Prepared And Informed, The Upwardly Floating Spirits Immediately Implied Something Much More Sensible, Not To Say More Interesting.

A Prepared And Informed Mind, Plus A Wealth Of Relevant Experience, Is What Susan Barry Brings To Thinking About The Fascinating Matter Of Vision. Her Account Turns On Personal Experience; She Was Cross-eyed As A Child, And Although She Had Corrective Surgery It Came Too Late For Her To Develop Stereoscopic Vision.
