Spinal reflexes and descending motor pathways section 3. We have concluded 1 that the effects of motor conditioning on the hreflex result from the discharge of renshaw cells activated by the antidromic volley in the motor axons, and 2 that the effects of sensory conditioning at the times used in these experiments are largely due to the activation of renshaw cells secondary to the discharge of alpha motoneurones by the conditioning volley.
