To locate the brain areas involved in female sexual behavior, various parts of the hypothalamus of the female macaque monkey were stimulated under partially-restrained conditions with the partner male in front of her. Immediately after the stimuli (duration:0.5 ms; frequency:50 Hz; pulse number:125; intensity: 300-500 μA), delivered to the preoptic area, lateral, dorsomedial, ventromedial and posterior hypothalamus, the female moved her body restlessly and extended her legs touwards the partner . This behavior was in some cases followed by presenting-like posture; the stimulated female lifted her rump towards the partner responding to the partner's touching. Since these behaviors occurred reproducibly after the stimulus and were seen only in the female, these behaviors were considered to be stimulus-evoked ones and components of female sexual behavior. The results suggest that the hypothalamus has facilitatory roles in the sexual behavior of the female monkey.
