Saccadic eye movements (saccades) in primates organize the visual info
rmation about the environment into a pulsatile course. Recent studies
from our laboratory have found substantial single unit activity, of ex
tra-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 me
dial temporal cortex as well as medial septum. Significant event-relat
ed potentials were recorded in both regions (again even in the dark).
These data suggest that higher level processing itself may synchronize
with saccades.
