title: Effects of medial preoptic lesions on male mouse ultrasonic vocalizations and copulatory behavior.
abstract: In male mice, lesions in the medial preoptic area (MPA) reduced the proportion of animals showing mounting behavior but failed to abolish ano-genital exploration of the female. The lesions did not effect the amount of 70 kHz ultrasound elicited by intact females or by soiled bedding obtained from female-occupied cages. These results suggest components of male sexual behavior are mediated by neural systems outside the MPA.
