Experimental arrangement. The dorsal roots were cut to record extracellular spikes of single interneurons excited by recurrent collaterals of PMNs and recurrent-IPSPs. EAS nerve, muscle nerve of the external anal sphincter muscle; EUS nerve, muscle nerve of the external urethral sphincter muscle. Perineal nerve innervates the bulbospongiosus and ischiocavernosus muscle. Stim., stimulation
