Fig. 1From: Reflex erection in the rat: reciprocal interplay between hemodynamic and somatic eventsA representative reflex erection recording (a). Electrical stimulation of the dorsal penile nerve induced one to three (as in this recording) waves of tonic intracavernous pressure increase and bursts of bulbocavernosus muscle electromyogram. Concurrent with the perineal muscles contractions phasic peaks of intracavernous pressure occurred. Scale bar - 30 s. A “single” (b), “double” (c) and “serial” (d) bulbocavernosus EMG bursts. Scale bars - 2 mV/500 msBack to article page
