VISUAL-EVOKED POTENTIALS IN RESPONSE TO FLASHES IN THE CAT CORTEX

A model is presented of visually evoked potentials (VEPs) in the cereb ral cortex of cats after binocular stimulation by means of flashes. Th e VEPs consist of four components: P-1, N-1, P-2 and N-2 which appear during the first 100 ms after the stimulation is produced. This model has been found in all the animals used in the experiments and is repea ted with small variations at almost all the recording points. After st udying the data obtained, a hypothesis is put forward for the possible origin of the four components in the primary visual area.
