[Effect of the intensity of repeated splanchnic nerve stimulation on the 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 degree of habituation was inversely related to the intensity of stimulation. The application of maximal stimulus intensity produced sensitization which turned into habituation with increase of the frequency of stimulation from 1 to 5/sec. The effect of the intensity increment told in changes of the 2nd component of the EPs. The data obtained are considered from standpoints of the theory stimulus--model comparer and the dual-process theory.
