Neuronal activity changes in the medial preoptic area (MPOA) of the male monkey were related to the commencement of sexual behavior, penile erection and the refractory period following ejaculation. Similarly, changes in the female MPOA were related to the commencement of sexual behavior and presentation. Increased neuronal activity in the dorsomedial hypothalamic nucleus (DMH) in the male monkey and in the ventromedial hypothalamic nucleus (VMH) in the female monkey was synchronized to each mating act. Stimulation study and neuronal activity recordings in the MPOA, DMH and VMH suggest involvement of MPOA neurons in sexual arousal, and of male DMH and female VMH neurons in the copulatory act. Stimulation experiment on the various parts in the hypothalamus of the female monkey also supports the conclusion.
雄性猴子内侧视前区（MPOA）的神经元活动变化与性行为的开始、阴茎勃起以及射精后的不应期有关。同样，雌性MPOA的变化与性行为的开始和表现有关。雄性猴子背内侧下丘脑核（DMH）和雌性猴子腹内侧下丘脑核（VMH）中神经元活动的增加与每次交配行为同步。对MPOA、DMH和VMH的刺激研究及神经元活动记录表明，MPOA神经元参与性唤起，雄性DMH和雌性VMH神经元参与交配行为。对雌性猴子下丘脑各部位的刺激实验也支持这一结论。
