Summary

Experiments were performed on cats in decerbrate rigidity. Stimulation of the central ends of some nerves to the quadriceps femoris muscle (100 stimuli per second) evoked a steady contraction or relaxation of the other heads of this muscle. Contractions corresponding to the myotatic reflex are observed with comparatively weak stimuli. Contractions appeared and increased in amplitude in response to stimulation of afferent fibers of Group I (with stimulus intensities up to 1.8–2 times threshold intensity, and with conduction velocities of 70 m/sec and above). Proprioceptive inhibition developed with relatively strong stimuli (more than twice threshold intensity), and was connected with activity of afferent fibers of Group II (conduction velocity of 70–35 m/sec), although the possible importance of antidromic impulses in efferent fibers is not completely excluded. The idea that tendon receptors are of decisive importance in the origin of autogenetic inhibition has not been confirmed. Substantial differences are displayed in the character of reflex excitation and inhibition in individual animals.
