Partial disconnection of regenerated IA afferents in the homonymous motor pool. Intracellular records of motoneuron membrane potential during quick stretch (400 m/s; 1 mm) of the homonymous muscle. Representative data collected in terminal study of an anesthetized rat with the muscle re-innervated by its original nerve that was cut and surgically repaired 1 year earlier. EPSPs normally present in all motoneurons were smaller than normal and absent in 2/5 motoneurons.
