南非爪蟾（Xenopus laevis）的求偶行为受到雄性激素的控制。放射自显像研究表明雄激素集中的神经元存在于运动核中，运动核控制求偶，中脑核受声音刺激。喉部运动神经元的激素浓度表明类固醇调节了发声行为的最终共同途径。激素对听觉敏感性的调节可以解释对同种鸣叫的行为反应的季节性变化。
Mate calling by South African clawed frogs,Xenopus laevis, is under the control of androgens. Autoradiographic studies demonstrate androgen-concentrating neurons in a motor nucleus that controls mate calling and a midbrain nucleus that is stimulated by sound. Hormone concentration by laryngeal motor neurons suggests that steroids regulate the final common path for vocal behavior. Modulation of auditory sensitivity by hormones could explain seasonal variations in behavioral responsiveness to conspecific vocalizations.
