visual suppression


Show Summary Details

Quick Reference

Momentary suspension of visual perception during a saccade, triggered by feedforward of the efferent output of the extra-ocular muscles, eliminating the impression of movement that would otherwise be created by the motion of the eyes, which cause movements of the images across the retinas. If a visual display linked to an automatic eye-movement tracker is altered only during saccades, the viewer does not perceive the changes occurring but may eventually become conscious of the fact that the image is no longer the same as it was. Also called saccadic suppression.
