在金丝雀中，男性歌曲（性感歌曲，SS）的特定短语很难产生，对女性特别有吸引力。与听非性感歌曲（NS）的雌性相比，听SS的雌性会产生更多的交配表现，并在卵子中储存更多的睾丸激素。在雌性鸣禽的听觉前脑中，已经观察到直接早期基因c-Fos或zenk（又名egr-1）的表达增加。本研究对暴露于SS或NS或对照白噪声60分钟后30分钟采集的雌性金丝雀大脑中C-Fos免疫反应性（Fos-ir）细胞数量进行了定量分析。与对照组相比，SS鸟类尾侧中膜（CMM）和尾侧内膜（NCM）中Fos-ir细胞数量增加。播放歌曲（合并播放SS和NS）也有增加中基底下丘脑（MBH）中Fos-ir细胞平均数量的趋势，但这种影响没有达到完全的统计学意义。在个体水平上，CMM中的Fos表达与其在NCM和MBH中的表达相关，但也与雌性对回放做出反应的叫声频率相关。因此，这些数据表明，不同质量的雄性歌曲诱导NCM和CMM的不同代谢激活。听觉区域的激活与MBH之间的相关性可能反映了听觉刺激与行为和生殖生理变化之间的联系。
In canaries, specific phrases of male song (sexy songs, SS) that are difficult to produce are especially attractive for females. Females exposed to SS produce more copulation displays and deposit more testosterone into their eggs than females exposed to non-sexy songs (NS). Increased expression of the immediate early genes c-Fos or zenk (a.k.a. egr-1) has been observed in the auditory forebrain of female songbirds hearing attractive songs. C-Fos immunoreactive (Fos-ir) cell numbers were quantified here in the brain of female canaries that had been collected 30 min after they had been exposed for 60 min to the playback of SS or NS or control white noise. Fos-ir cell numbers increased in the caudomedial mesopallium (CMM) and caudomedial nidopallium (NCM) of SS birds as compared to controls. Song playback (pooled SS and NS) also tended to increase average Fos-ir cell numbers in the mediobasal hypothalamus (MBH) but this effect did not reach full statistical significance. At the individual level, Fos expression in CMM was correlated with its expression in NCM and in MBH but also with the frequency of calls that females produced in response to the playbacks. These data thus indicate that male songs of different qualities induce a differential metabolic activation of NCM and CMM. The correlation between activation of auditory regions and of the MBH might reflect the link between auditory stimulation and changes in behavior and reproductive physiology.
