Losing facial recognition is a small price to pay to keep Superman forever anonymous. Clark Kent’s face could never be matched to Superman’s because no one who got a good look at both of them would be able to describe it. As his friends, love interests, and co-workers slept, Superman could slip in, X-ray the skull to find the fusiform gyrus, and use his heat vision to lesion it. When venturing outside his special cluster of cognitively impaired colleagues, Superman could keep his identity secret with selective surgery. His friends and colleagues would be able to recognize one another easily enough, but Superman’s out-thrust chest, booming voice, and festively colored tights would never match that hunched, stammering, bespectacled new reporter. Likewise, a prosopagnosic can’t distinguish different faces, because within the “face” category a nose is a nose-not Superman’s or Clark Kent’s.Įverything that a prosopagnosic relies on to recognize someone is different for Superman and Clark Kent. In rare cases, bird-watchers and car lovers with lesions to the fusiform gyrus have lost the ability to distinguish types of birds or cars. But the fusiform gyrus isn’t just a face-recognizer it helps you make fine distinctions within visually similar categories. The gyrus, one on the underside of each hemisphere of your meaty mind, activates in response to faces when it’s damaged, people rely on patterns and voices instead. * A stroke that damages the fusiform gyrus is the most common way to induce face blindness. Though some people are born with this disorder, others who suffer from prosopagnosia acquire it through trauma to certain areas of the brain. For many people with disorders like these, the symptoms are taken for granted as simply how the world “looks.” They may not find out that anyone sees faces differently until later in life. Neuroscientist Oliver Sacks-author of The Man Who Mistook His Wife for a Hat, a case study of visual agnosia-discovered that he, too, had prosopagnosia after mistaking one of his brothers for the other. It’s no wonder nobody at the Daily Planet can match this constellation of clues to Superman in his cape. So for prosopagnosics, Clark Kent is a familiar assortment of suits, nervous mannerisms, and glasses. She responded that it could be one of her neighbors. A team of scientists showed a woman with prosopagnosia her own image and asked her what she saw. In the first recorded case of the disorder, Jean-Martin Charcot (considered by some to be the father of modern neurology) in 1883 described a patient who mistook his own reflection in a mirror for a stranger and apologized for blocking the way. But the ability to recognize a person from the face alone evaporates. They aren’t even all that socially disabled: They rely on voices, gaits, and typical clothes to identify people. People with face blindness can read, drive, and even realize that what they are looking at is a face. Other areas of visual perception remain (mostly) intact. Prosopagnosia is a brain disorder that severely limits a person’s ability to recognize and remember faces. Since a Kryptonian's senses are inhumanly high, uncontrollable and unstable when first discovered, it can cause a Kryptonian to randomly see through objects at varying levels, which, along with their extremely powerful other senses, can initially overwhelm and agonize them, as was the case with General Zod and Faora-Ul.But science fiction can do way better than that. With this ability Kal-El easily saw through a one-way mirror and several walls simultaneously. Kryptonians can mentally break down the polymers layer by layer in objects and organisms, allowing them to clearly see through the object or person. The extremely few objects impenetrable to Kryptonian x-ray vision are the force field of a Kryptonian Breather (when rendered opaque), and objects made of lead. X-Ray Vision is the exclusively Kryptonian ability to see through and beyond almost any solid objects, by viewing the entire electromagnetic spectrum.
