|Abstract / Description:||Although saccadic eyemovements can radically change the retinal image, perceptually their impact is surprisingly small. Here, we investigate possible neuronal correlates of saccadic suppression in cats freely viewing natural stimuli.By comparing changes attributable to saccadic events with passive stimulus changes, we ¢nd that during saccades: (i) evoked and induced activity is reduced in areas|
18 and 21a by equal amounts, (ii) the variability of neuronal activity
with stimulus category is abolished in both areas, and (iii) the highpower
transient induced by stimulus change is not observed.
These results present electrophysiological evidence for saccadic suppression at the level of primary and higher visual cortex under natural conditions.
