A 23-year-old German student can arbitrarily zoom and zoom in his pupils on demand - a previous miracle is said to be impossible 9: 00/3: 21-year-old male opposition Eyes have the function of controlling the size per pupil (dark area in the eye center), stretching or expanding them in a dark environment to gain more light and shrink in the morning environment to limit the amount of light transmisson in. Pobes can also resize to react to other factors, such as when excited. Before we already know that some people can resize their pupils as desired , But by using indirect methods. For example, researchers know that only thinking about the sun can cause pupils and think of dark rooms or calculate something that can make them relax, according to Christoph Strauch, the premium author of the newspaper The fox of new cases and an assistant professor of experimental psychology at Utrecht University in the Netherlands said. But no one thought it was possible to change the pupil size by controlling it directly as a muscle
. Corn until a psychology student at Ulm University in Germany contacted Strauch after joining one of his courses. (Strauch was previously a doctoral student at Ulm University). At the time of the subject of about 15 or 16 years old, the young man - was determined in the report with his name DW - realized that I can arbitrarily change the pupil size
"Covering the pupil felt like she was holding tightly, stretching something; While making it greater feel like the eyes are relaxed, completely liberated ", d.w. Tell the researchers.Banciful, he resized his pupils by focusing on the front or behind an object, but through practice, he learned how to do it without needing Focus on any object. He told the researchers that, to change his pupil size, all he needed to do was focus on his eyes; You don't need to imagine being in a morning or dark environment. That makes D.W different from those who show other pupils. Moreover, the fact that he could feel the muscles directly in the pupil "was amazing, because it was said to be impossible." Through a series of tests, the researchers have confirmed that DW really has this ability - and they do not find any signs that he is indirectly changing its pupils. In an experiment, the researchers measured the electrical characteristics of the degree skin How to apply the voltage to check if he is irritated by strengthening the mental effort, this can also increase his pupil size indirectly
The result is of course not. No need to use any indirect method, DW can relax your pupil with a diameter of up to 0.09 inches (2.4 mm) and shrink with the diameter longer 0.03 inches (0.88 mm). Using a brain scan called resonance from function (FMRI), researchers find an increase in activation in some parts of the brain Regarding the initiative, or the ability to voluntarily decide and do something at its disposal. The researchers cannot be sure that DW is directly controlling his pupil, but from many tests, They did not find any evidence that he used indirect strategies. Does another person can learn to do as d.w. are not? Strauch answered yes. Research on many people with this ability can help researchers describe and understand the phenomenon, such as where it comes from, Strauch added. "Pretty many people believe that they can do the same thing contacted, this is really great," he said. . Dịch vụ:
