ABSTRACT
Research has shown that trajectories of saccadic eye movements are often curved away from distractor stimuli that need to be ignored. On some trials, observers had to ignore a peripheral stimulus that was presented. The results revealed that saccades deviated away from the location of that stimulus. When the eyes went correctly to the color singleton target, saccade trajectories deviated away from the location of the onset stimulus. Typically, curvature away from a to-be-ignored stimulus has been attributed to inhibition of stimulus-related activity. Because of this inhibition, the overall population of activity generates a saccade vector that deviates away from the location of the stimulus. Thus, research has shown that eyes may deviate away from visible stimuli that need to be ignored. If the process of remembering a certain location is the same as the process of programming an eye movement to that location, remembering a location will generate corresponding activity in the superior colliculus.
