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.
在雄性小鼠中，内侧视前区（MPA）的损伤降低了表现出爬跨行为的动物比例，但并未消除对雌性动物肛门生殖器的探索。这些损伤并未影响完整雌性小鼠或从雌性占据的笼子中获取的脏垫料所引发的70千赫兹超声波的量。这些结果表明，雄性性行为的组成部分是由MPA以外的神经系统介导的。
