[Changes in the efferent activity of the scratching generator evoked by external mechanical force applied to a hindlimb in the decerebrate cat].

Changes in the afferent inflow appeared with application of the external mechanical force to the rhythmically moving hindlimb have been studied for their scratching generator activity in decerebrate adult cats. Phasic relationship between violent hindlimb transference and efferent activity of the scratching generator was opposite to that found earlier during fictitious scratching, which is explained by difference between afferent activity during real scratching movement and passive movement of the hindlimb in the immobilized animal. Maximum redistribution in the relationship between flexor and extensor intensities in response to the stimulation corresponds to maximum rate of the violent hindlimb transference.
