title: Saccadic eye movements, even in darkness, generate event-related potentials recorded in medial sputum and medial temporal cortex.
abstract: Saccadic eye movements (saccades) in primates organize the visual information about the environment into a pulsatile course. Recent studies from our laboratory have found substantial single unit activity, of extra-retinal origin, in medial temporal and inferotemporal cortex with each saccade (even in the dark). In the current experiment we studied event-related potentials to spontaneous saccades from electrodes in medial temporal cortex as well as medial septum. Significant event-related potentials were recorded in both regions (again even in the dark). These data suggest that higher-level processing itself may synchronize with saccades.
