Abstrakt: Acute experiments were carried out on anesthetized adults cats. We studied changes in the latency of the positive phase of high-voltage evoked potentials recorded from the medial suprasylvian gyrus and from the anterior part of the lateral gyrus, and their dependents on the intensity of peripheral stimulation.1)During electrical stimulation of the muscular branch of the radial nerve increase in intensity of the stimulus leads to a shortening of the latency of the positive stage of evoked potentials recorded from the medial suprasylvian gyrus and the anterior part of the lateral gyrus.2)Variation in the latency of evoked potentials recorded from any given area of the cat brain under constant conditions of stimulation of the cutaneous branch of the radial nerve is practically negligible.
