Life’s A Blur — But We Don’t See It That Way
Since we do not notice our constant saccades, this suggests that the brain specifically suppresses the signals that reach our retina while a saccadic eye movement is in process. In experiments with macaques that were trained to make predictable saccades, brain cells that receive signals from one particular spot in the retina switched from responding to things currently in view there to things that would show up only after the saccade. Wurtz and others believe that this kind of signal nudges brain cells to start responding to things that their part of the retina will see only after the saccade.
