Visual evoked potentials to patterned stimulation of the upper and lower half of the visual field were investigated in nine adult Ss. The inter-stimulus interval varied between 350 and 2,600 msec. With patterned stimulation, no inter-stimulus interval effects were obtained for occipital components. In contrast for the vertex lead, on the other hand, as inter-stimulus interval increased, the N140-P200 amplitude increased. Because of the heterogeneity subjects' responses evoked by upper half-field stimulation, this effect was more pronounced in lower half-field stimulation.
