Abstract : Five experiments were conducted. The first study was concerned with the nature of the visual evoked potential (VEP) at, above and below two-flash threshold. The second experiment explored the nature of the VEP under conditions of sequential blanking. In the third experiment VEPs were recorded under conditions in which the normally blanked stimuli and blanking stimuli were alternately increased in luminance. The fourth experiment involved the recording of evoked potentials from four different cortical areas under conditions of sequential blanking. The final experiment of this years report investigated VEPs as a function of three different stimulus configurations and one additional stimulus condition termed sequential displacement. (Author)
