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.
南非爪蟾(非洲爪蟾)的求偶鸣叫受雄激素控制。放射自显影研究表明,在一个控制求偶鸣叫的运动核以及一个受声音刺激的中脑核中有雄激素聚集神经元。喉运动神经元的激素浓度表明,类固醇调节发声行为的最后共同通路。激素对听觉敏感性的调节可以解释对同种发声行为反应的季节性变化。
