What do V1 neurons tell us about saccadic suppression?

A series of neurophysiological experiments on the responses of V1 neurons during saccadic eye movements were carried out. Strong suppression followed by rebound was observed in post-saccadic neural activities. These results showed that although the reduction in perceptual sensitivity during rapid eye movements was largely due to the smearing of visual stimuli during saccades, there exist saccade-related extraretinal signals mediating saccadic suppression at the neuronal level. Key Words Saccadic suppression; Orientation tuning; Primate visual cortex; Eye movement
