Abstract
The slow potential (SP) changes elicited in the cerebrum by rhythmic flash stimulation were led from the scalp above the rabbit visual cortex in awaked resting state. The time course of SP changes caused by rhythmic flash stimulation was traced at the same time as the summated average responses of evoked EEG responses, that is, visually evoked responses (VERs). The negative shifts of the cerebral SP changes were observed to be augmented. gradually, as the counts of stimulation increased. In the VERs, the same tendency was recognized as the time course of the negative shifts of the cerebral SP. The relationship between the negative shifts of the cerebral SP changes and VERs was discussed.
