概括

唱歌鸟中明显的水管灰色 (PAG) 柱子调节了与性动机或社会归属相关的不同类型的歌曲. 这表明保存的大脑结构控制了特定于背景的声音和社会行为.

科学领域:

神经伦理学神经伦理学
进行比较的神经解剖学.

背景情况:

男歌鸟在春天 (性动机) 和秋天 (社会归属) 唱歌.
哺乳动物的近水管灰色 (PAG) 集成了感官信息,并控制了反映情绪状态的发声.
唱歌鸟PAG的功能组织和在特定环境中唱歌的作用尚不清楚.

研究的目的:

为了调查歌鸟PAG内部有没有不同的柱子调节性动机和群居的歌声.
探索可能影响社会行为的PAG输入.

主要方法:

在唱歌不同类型后,在16个PAG子区域的雄性欧洲鸟中量化了ZENK阳性细胞.
进行了从中介前视核到PAG的功能性通道追踪.

主要成果:

不同的PAG列显示了与群体与性动机歌曲相关的差异激活模式.
从中介前视核到PAG的特定输入被确定,可能会影响群体性歌曲和社会主导行为.

结论:

研究结果表明,歌鸟中不同的PAG列在特定的背景下调节歌曲和相关的社会行为.
保存的PAG列和预视核输入可能在特定的语境声调和跨物种的社会相互作用中发挥作用.

Mate Choice

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
