A trio of brain and cognitive scientists at the University of Rochester, in the U.S., has found that eye blinking does more than simply wet the eyes—it also helps to keep vision sharp by maintaining the strength of visual ...
Johns Hopkins Medicine scientists say that new experiments with mouse eye tissues strongly suggest that a longstanding "textbook concept" about the way a mammal's retina processes light needs a rewrite.
