The author performed experiments with decerebrumized by Sher rington’s method cats. By the irritation of the ipsilateral n. регопеі a flexible reflex of the m. semitendinosus was attained, while the irritation of the contralateral n. регопеі blocked it. The summation of the blocks was proved by the experiments: an accumulation of the «block substance» and its gradual disappearance An explanation of an exceptional case of the «after block exaltation» was submitted. The feasibility of the block influence, when the stimulating irritation preceded that of the block by thousands parts of a second, was finally ascertained by experiments with two seperate inductional shocks, of which one caused a depression and the other an excitement. Moreover by juxstaposing the provisional relations a direct way was supposed to exist from the block impulses toward the last or last but one motive neuron of a given reflex, where their conflict with irritations takes place.
