Abstract

Spatial, temporal frequencies as well as orientations are important visual stimulus properties, which will affect human perception. In this paper, we investigated the effects of gratings with different spatial, temporal frequencies and orientations on visual evoked potentials. Two positive components (P1 and P2) were observed after stimulation. Our results showed that the amplitude of P1 component was higher for gratings with 0.3 cycles per degree (cpd) spatial frequency compared to 0.05 and 0.1 cpd. While the amplitude differences of P2 component occurred between 0.05 and 0.1 cpd. The amplitude of both components were higher when subjects were viewing gratings at vertical orientation than horizontal orientation.
