[Evoked potentials to sound in the visual cortex in the cat].
The obtained data on the appearance in the cat visual cortex (VC) of evoked potentials (EPs) with short (4-5 ms) and long (80-90 ms) latencies in response to sounds, lead to the conclusion about a complex, phasic character of VC activity change under the action of inadequate stimuli. The dependence of short-latency EPs on the sound intensity has been found, which is expressed in the initial increase of amplitude and a reduction of temporal parameters, followed by stabilization of their values at further increase of stimulation intensity. Cortical nature of the observed EPs has been proved.
