DOES THE BRAIN HAVE ITS OWN NIGHTVISIO­N CAMERA?

-

Even when it’s completely dark, the brain knows exactly what our hands are doing. U.S. researcher­s have discovered that the brain can send that informatio­n to the eyes, even in the total absence of visual stimuli. It turns out about 50% of us can “see” our own hands moving in the dark. Until now, most researcher­s dismissed the phenomenon described here as a mere illusion. But psychologi­st Kevin Dieter of Vanderbilt University lays out the facts: “What we normally perceive as sight is really as much a function of our brains as of our eyes. We get such reliable exposure to the sight of our own hand moving that our brains learn to predict the expected moving image. It’s a learned associatio­n.”
