社会信号在调节情感-行为关系中起着重要的作用。在无尾类动物（青蛙和蟾蜍）中，声音信号是生殖行为的一个重要方面;然而，接收社会信号的生理后果在很大程度上仍未被描述。每晚5，10，或20天，我们提出了声学孤立的雄性树蛙同种交配合唱，一系列的音调，或没有声音。在整个实验过程中，我们记录了个体的呼叫率，并在治疗前后采集了血液。刺激暴露的天数对任何相关指标都没有影响。声学处理影响类固醇水平;睾酮、二氢睾酮和皮质酮仅在接触合唱的组中增加。合唱团暴露的男性也表现出增加刺激诱发呼叫。我们没有发现雄激素和呼叫之间的相关性在每个治疗组。此外，合唱组中的noncallers有较高水平的雄激素比男性的音调或没有声音组。此外，合唱团暴露的男性与零，低，或高率的呼叫有类似的水平的雄激素。这些数据表明，社会信号增加循环雄激素独立的呼叫行为。与合唱接收皮质酮升高并没有抑制呼叫行为，皮质酮与雄激素水平没有相关性。(C)北京大学出版社.
Social signals play an important role in regulating hormone-behavior relationships. In anurans (frogs and toads), acoustic signals are an essential aspect of reproductive behavior; however, the physiological consequences of receiving social signals has remained largely undescribed. Each night for 5, 10, or 20 days, we presented acoustically isolated male treefrogs with a conspecific mating chorus, an array of tones, or no sound. We recorded calling rate of individuals throughout the experiment and collected blood before and after treatment. Days of stimulus exposure had no effect on any dependent measure. Acoustic treatment influenced steroid levels; testosterone, dihydrotestosterone, and corticosterone increased only in the group exposed to the chorus. Chorus-exposed males also showed an increase in stimulus-evoked calling. We found no correlation between androgens and calling within each treatment group. In addition, noncallers in the chorus group had higher levels of androgens than males in the tone or no sound groups. Further, chorus-exposed males with zero, low, or high rate of calling had similar levels of androgens. These data indicate that social signals increase circulating androgens independently of calling behavior. Elevated corticosterone associated with chorus reception did not inhibit calling behavior, and corticosterone showed no correlation with androgen levels. (C) 2000 Academic Press.
