a deficit in centrally discharged impulses. This implies that an inhibitory reflex either is unmasked or is substituted for the excitatory reflex. Other evidence for the existence of inhibitory reflexes has been found in the manifestation of terminal rebound in reflexes engendered by stimulation of afferent C fibers.'01I The second point of interest is that the spontaneous activity which is increased by heating suffers a depression on further heating (Fig. 4 B).
