title: Rhesus monkeys mislocalize saccade targets flashed for 100ms around the time of a saccade.
abstract: Humans and monkeys mislocalize targets flashed around the time of a saccade. Here, we present data from three monkeys on a double-step task with a 100ms target duration. All three subjects mislocalized targets that were flashed around the time of the first saccade, in spite of long intersaccadic intervals. The error was consistently in the direction opposite that of the saccade, and occurred in some cases when the target presentation was entirely presaccadic. This is inconsistent with a theory invoking a damped representation of eye position, but it is consistent with the hypothesis that it is due to an error in peri-saccadic remapping.
