The neurophysiology of remapping has tended to examine the latency of responses to stimuli presented around a single saccade. Using a visual foraging task, in which animals make multiple eye movements within a trial, we have examined predictive remapping in the lateral intraparietal area (LIP) and the frontal eye field (FEF) with a focus on when activity differentiates between stimuli that are brought on to the response field. We have found that the activity in LIP, but not FEF, rapidly shifts from a pre-saccadic representation to a post-saccadic representation during the period of saccadic suppression. We hypothesize that this sudden switch keeps attentional priorities of high priority locations stable across saccades and, thus, could create the illusion of perceptual stability.
