类固醇激素在调节对各种社会刺激的行为反应中起重要作用。研究表明，不同物种之间的激素调节行为的变化与社会组织和/或交配系统有关。为了进一步阐明激素和行为的相互作用，在社会的情况下，我们暴露男性的一夫一妻制定罪丽鱼Amatitliana nigrofasciata三个社会刺激：怀孕的女性，入侵者男性，和非社会刺激。我们使用重复测量设计来创建行为特征，并探索性类固醇激素如何响应和调节社会行为。结果表明，不同的社会情况下，不同的行为反应，与循环11-酮睾酮增加社会刺激。药理学操作使用特定的雄激素和雌激素受体激动剂和拮抗剂暴露复杂的控制挖掘行为的社会机会的背景下。在社会挑战的背景下，攻击行为减少响应阻断雄激素受体途径。我们的研究结果扩展了我们对性类固醇调节社会刺激行为反应的理解。(C)2013 Elsevier Inc.

Steroid hormones play an important role in modulating behavioral responses to various social stimuli. It has been suggested that variation in the hormonal regulation of behavior across species is associated with social organization and/or mating system. In order to further elucidate the interplay of hormones and behavior in social situations, we exposed males of the monogamous convict cichlid Amatitliana nigrofasciata to three social stimuli: gravid female, intruder male, and a nonsocial stimulus. We used a repeated measure design to create behavioral profiles and explore how sex steroid hormones respond to and regulate social behavior. Results show distinct behavioral responses to different social situations, with circulating 11-ketotestosterone increasing in response to social stimuli. Pharmacological manipulations using specific androgen and estrogen receptor agonists and antagonists exposed complex control over digging behavior in the social opportunity context. In the social challenge context, aggressive behaviors decreased in response to blocking the androgen receptor pathway. Our results extend our understanding of sex steroid regulation of behavioral responses to social stimulation. (C) 2013 Elsevier Inc. All rights reserved.
