性腺激素调节对性刺激的行为反应,通信信号也可以调节循环激素水平。在一些物种中,这些综合效应似乎是循环性腺激素和对社会显着刺激的行为反应之间双向相互作用的基础。最近对鸣禽的研究表明,控制听觉前脑中的局部雌二醇水平会产生生理变化,影响同种发声的辨别并影响行为。这些研究提供了新的证据,证明雌激素可以直接改变听觉处理并间接改变对刺激的行为反应。这些研究表明:1)听觉区域内的局部雌二醇作用对于社会相关声音诱导两性大脑中的正常生理反应是必要的; 2)这些生理效应发生的速度比基因组效应的经典时间框架预测的要快得多; 3)雌二醇在听觉前脑内的作用使得男性能够区分社会相关声音的行为; 4) 雌二醇是在特定的社交互动过程中在男性大脑中局部产生的。越来越多的证据表明了一个社会神经内分泌学框架,其中雌二醇对于听觉处理至关重要,通过社会相关刺激而增加,迅速作用以形成对社交互动期间经历的后续刺激的感知,并调节对这些刺激的行为反应。大脑雌激素在两性鸣禽中的功能可能相似,因为雄性和雌性前脑中都存在芳香酶和雌激素受体。雌激素对鸣禽和其他动物感知的调节可以微调雄性广告信号和雌性区分它们的能力,通过调节行为促进配偶选择。(PsycINFO 数据库记录 (c) 2016 APA,保留所有权利)
Gonadal hormones modulate behavioral responses to sexual stimuli, and communication signals can also modulate circulating hormone levels. In several species, these combined effects appear to underlie a two-way interaction between circulating gonadal hormones and behavioral responses to socially salient stimuli. Recent work in songbirds has shown that manipulating local estradiol levels in the auditory forebrain produces physiological changes that affect discrimination of conspecific vocalizations and can affect behavior. These studies provide new evidence that estrogens can directly alter auditory processing and indirectly alter the behavioral response to a stimulus. These studies show that: 1) Local estradiol action within an auditory area is necessary for socially relevant sounds to induce normal physiological responses in the brains of both sexes; 2) These physiological effects occur much more quickly than predicted by the classical time-frame for genomic effects; 3) Estradiol action within the auditory forebrain enables behavioral discrimination among socially relevant sounds in males; and 4) Estradiol is produced locally in the male brain during exposure to particular social interactions. The accumulating evidence suggests a socio-neuro-endocrinology framework in which estradiol is essential to auditory processing, is increased by a socially relevant stimulus, acts rapidly to shape perception of subsequent stimuli experienced during social interactions, and modulates behavioral responses to these stimuli. Brain estrogens are likely to function similarly in both songbird sexes because aromatase and estrogen receptors are present in both male and female forebrain. Estrogenic modulation of perception in songbirds and perhaps other animals could fine-tune male advertising signals and female ability to discriminate them, facilitating mate selection by modulating behaviors.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
