[Influence of frequency of splanchnic nerve stimulation on development of habituation in the cat cerebral cortex].

Changes of amplitude of evoked potentials in the areas SI and SII of the cortex on repeated stimulation of the splanchnic nerve were studied in anesthetized and immobilized cats. The rate of decrement amplitude responses is increased with increasing of the frequency of stimulation from 0.5 to 5 stimuli per 1 sec. in the focus of maximal activity and in peripheral areas SI and SII. The decrement responses are more obvious in the peripheral sites of these areas. The data obtained seem to indicate a development of habituation in the cortex.
