Electrical stimulation of the anterior preoptic nucleus elicited the production of mating calls by male Hyla arborea savignyi. Such calls are composed of pulses resembling those of natural mating calls both in their duration and in their sequential arrangement. As a rule, the amplitude of successive pulses within a group increases more rapidly in the electrically evoked calls than in natural calls. The frogs could be brought into a state of readiness to call, which did not lead to actual calling activity, by stimulation in the anterior preoptic, posterior preoptic, and magnocellular nuclei as well as in the hypothalamus. Stimulation of the anterior preoptic nucleus of one female elicited repeated vocalizations, which may be interpretable as mating calls. The posture adopted by the female for spawning can be elicited in males as well as in females by electrical stimulation of the anterior preoptic nucleus.
电刺激前视前核可引发雄性华西雨蛙发出求偶叫声。此类叫声由脉冲组成，其持续时间和序列排列与自然求偶叫声的脉冲相似。通常，在电诱发的叫声中，一组内连续脉冲的幅度比自然叫声中增加得更快。通过刺激前视前核、视前后核、大细胞神经核以及下丘脑，可使青蛙进入准备鸣叫状态，但不会引发实际的鸣叫活动。刺激一只雌性的前视前核会引发重复发声，这可能被解释为求偶叫声。通过电刺激前视前核，雄性和雌性青蛙都会呈现出雌性产卵时所采用的姿势。
