[Effect of stimulation of interanalyzer association areas of rabbit cortex on evoked potentials and neuronal responses of the visual cortex].
The study was concerned with functional influences of associative cortical areas on EPs and neuronal responses to flashes in the visual projection zone of a rabbit. Stimulation of the anterior associative cortical parts leads to a prolongation of the inhibitory pause and to a decrease of late discharges in responses of visual cortical neurones which is manifested in a significant reduction of the secondary negative-positive EP complex. Stimulation of the posterior associative area causes a prolongation and a deepening of the inhibitory pause in the neuronal activity and an increase of late discharges in the neuronal response in the visual cortex with a corresponding significant enhancement of the secondary negative-positive EP complex. Different mechanisms of functional effects of the anterior and posterior interanalyser brain parts on the visual projection area are suggested.
