In vivo intensity thresholds for ring and 3-ring electrodes at 2 cm from the urethral meatus. (A) The thresholds for evoking an EAS reflex for stimulation at 2 cm from the urethral meatus were greater for stimulation with the 3-ring electrode than for stimulation with the ring electrode in 4 of 4 cats. (B) The normalized, average stimulation intensities revealed that stimulation with the ring electrode evoked an EAS reflex at significantly lower threshold than stimulation with the 3-ring electrode (*p < 0.0005, paired one-sided t-test).
