Influence of the delabyrinthation on processes of exaltation and inhibition of flexor and extensor motor-neurones, which are activated by afferents of the muscle-antagonist nerve

Abstract

In researches, conducted on cats after delabyrinthation, was ascertained a decrease of weakening action of Strychninum on the eariy phase of inhibition of flexor and extensor motor-neurones with a maximum of display on 3-6 ms and duration of 7-10 ms as compared was observed in conditions of conservation of labyrinthes. The late phase of the inhibition with a maximum on 30-80 ms and duration of 100-200 ms amplified. Possible physiological mechanisms of the registered phenomena are discussed.
