雄性欧洲椋鸟（Sturnus vulgaris）全年都会唱歌，但激发唱歌行为的社会因素因歌曲产生的环境而异。在非繁殖环境下（当睾丸激素浓度较低时），椋鸟会形成大型的混合性别的鸟群，而歌声则与鸟群的凝聚力有关，也许还能维持社会等级。相比之下，在繁殖环境中（当睾丸激素浓度高时），雄性歌曲在配偶吸引力中起着直接作用。神经系统如何确保在适当的环境中对适当的刺激做出反应而产生歌曲还没有得到很好的理解。歌曲控制系统调节歌曲的产生、学习，在一定程度上还调节感知;然而，这些核团似乎并不调节歌曲产生的社会环境。基底前脑和中脑的类固醇激素敏感核网络调节社会行为。本研究使用即时早期基因cFOS来探索这些区域可能参与情境依赖的歌曲产生。终纹内侧床核，下丘脑前部和下丘脑腹内侧核的cFOS标记细胞的数量呈正相关，只有在育种背景下产生的歌曲。与此相反，cFOS标记的细胞在三个区的侧隔呈正相关，只有在非繁殖的背景下产生的歌曲。两者合计，这些数据表明差异调节雄性椋鸟歌曲的社会行为核取决于它产生的繁殖环境。(c)2006年爱思唯尔公司All rights reserved.
Male European starlings (Sturnus vulgaris) sing throughout the year, but the social factors that motivate singing behavior differ depending upon the context in which song is produced. In a non-breeding context (when testosterone concentrations are low), starlings form large, mixed-sex flocks and song is involved in flock cohesion and perhaps maintenance of social hierarchies. In contrast, in a breeding context (when testosterone concentrations are high), male song plays a direct role in mate attraction. How the nervous system ensures that song production occurs in an appropriate context in response to appropriate stimuli is not well understood. The song control system regulates song production, learning, and, to some extent, perception; however, these nuclei do not appear to regulate the social context in which song is produced. A network of steroid hormone sensitive nuclei of the basal forebrain and midbrain regulates social behavior. The present study used the immediate early gene cFOS to explore possible involvement of these regions in context-dependent song production. Numbers of cFOS-labeled cells in the medial bed nucleus of the stria terminalis, anterior hypothalamus, and ventromedial nucleus of the hypothalamus related positively only to song produced in a breeding context. In contrast, numbers of cFOS-labeled cells in three zones of the lateral septum related positively only to song produced in a non-breeding context. Taken together, these data suggest differential regulation of male starling song by social behavior nuclei depending upon the breeding context in which it is produced. (c) 2006 Elsevier Inc.
