When Susan Barry first wrote to Oliver Sacks, she never expected a response, let alone the deep friendship that blossomed over ten years of letters. Sue, herself a neuroscientist, wrote to share an extraordinary development in her own medical history. Born with problems with her vision, Sue had been told she would never acquire the ability to see in 3D - and yet she did, a development at odds with decades of research. Within days, Oliver replied, "Your letter fills me with amazement and admiration."

When neuroscientist Susan Barry was 50 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.

We think of perception as a passive, mechanical process, as if our eyes are cameras and our ears microphones. But as neurobiologist Susan R. Barry argues, perception is a deeply personal act. Our environments, our relationships, and our actions shape and reshape our senses throughout our lives. This idea is no more apparent than in the cases of people who gain senses as adults. Barry tells the stories of Liam McCoy, practically blind from birth, and Zohra Damji, born deaf, in the decade following surgeries that restored their senses.
