N-methyl-D-aspartic acid (NMDA) or radiofrequency (RF) lesions were made in the paraventricular nucleus of the hypothalamus (PVH) of male rats. The rats were tested for copulation, noncontact erection (NCE) evoked by remote cues from estrous females, and (after RF lesions) reflexive erection. NMDA, which destroyed parvocellular but spared magnocellular neurons, caused no deficits in copulation but caused longer NCE latencies and fewer NCEs. Rats with RF lesions had parvo- and magnocellular… CONTINUE READING
