Abstrakt: When the rat spinal motor centre was activated by fixing the animal in a supine posture, the motor units of intact gastrocnemius muscle fired more frequently in the high-frequency range. Under conditions of the ischiatic nerve blockade, a shift to an increase in the background firing frequency of the motor units related to intact gastrocnemius muscle seems to be related to increased motoneurone excitability occurring because of the contralateral denervation.
