STIMULATION FREQUENCY AND VISUALLY EVOKED SCALP POTENTIALS WITH BRIEF FLASHES OF LIGHT

Abstract
Recording of the visually evoked scalp potential (VESP) elicited with flash stimulation was completed in 6 subjects [human] presenting with normal vision. From the 4 separate signals recorded over the visual cortex it was concluded that stimulation frequency affects some of the components of the VESP. In studies of the VESP, the influence of stimulation frequency is a critical factor which must be taken into account when analyzing the resultant activity.
