在哺乳动物和鸟类中，发声是性和社会信号的重要媒介。在除人类以外的大多数哺乳动物中，发声是由先天机制指定的，并且在没有听觉经验的情况下正常发育。相比之下，幼年鸣禽会记住并复制成年导师的歌曲，这一过程与人类的语言学习有许多相似之处。尽管发声学习对人类语言至关重要，但人类和鸣禽的发声都利用了先天发声的祖先回路，有效的发声交流取决于先天和后天元素的流畅融合。这篇综述涵盖了我们对鸟类和小鼠习得性和先天性发声的中枢机制的理解的最新进展，包括脑干机制，有助于“门”发声或关闭，皮质参与习得性和先天性发声，以及评估和加强歌曲表现以促进声乐学习的电路的描绘。
Vocalizations are an important medium for sexual and social signaling in mammals and birds. In most mammals other than humans, vocalizations are specified by innate mechanisms and develop normally in the absence of auditory experience. By contrast, juvenile songbirds memorize and copy the songs of adult tutors, a process with many parallels to human speech learning. Despite the centrality of vocal learning to human speech, vocal production in humans as well as in songbirds exploits ancestral circuitry for innate vocalizations, and effective vocal communication depends on the fluent blending of innate and learned elements. This review covers recent advances in our understanding of central mechanisms for learned and innate vocalizations in birds and mice, including brainstem mechanisms that help to 'gate' vocalizations on or off, cortical involvement in learned and innate vocalizations, and the delineation of circuits that evaluate and reinforce song performance to facilitate vocal learning.
