为了研究鸣禽鸣唱行为与大脑基因调控的生态相关性，我们在其繁殖区域内对自由范围内的鸣唱麻雀进行了同种歌曲回放的挑战。雄性的反应是接近扬声器，寻找入侵者并积极唱歌。在原位杂交的大脑切片显示，在几个听觉结构和歌曲控制核的转录调节ZENK的表达在挑战鸟类比在未受刺激的控制。我们的结论是，在领土防御的背景下唱歌的行为与控制歌曲的感知和生产的大脑中心的基因调控，行为调控的基因表达可用于调查参与自由活动的动物的自然行为的大脑区域。
To investigate the ecological relevance of brain gene regulation associated with singing behavior in songbirds, we challenged freely ranging song sparrows with conspecific song playbacks within their breeding territories. Males responded by approaching the speaker, searching for an intruder and actively singing. In situ hybridization of brain sections revealed expression of the transcriptional regulator ZENK in challenged birds than in unstimulated controls in several auditory structures and song control nuclei. We conclude that singing behavior in the context of territorial defense is associated with gene regulation in brain centers that control song perception and production, and that behaviorally regulated gene expression can be used to investigate brain areas involved in the natural behaviors of freely ranging animals.
