项目摘要

The bird song system has many parallels to human speech development and maintenance. Like humans, birds depend on hearing their own vocalizations in order to produce song. The main goal of this proposal is to test whether birds can adapt their vocalizations when auditory feedback is altered and characterize the neural basis for these behavioral changes. This will be tested by recording the birds song and playing loud burst of white noise whenever the bird sing a particular pattern of sounds. The playback of white noise targeted at a particular segment of song induces an auditory error signal. In order to reduce this error signal, the bird can either stop singing the targeted sound or change the spectral structure of that sound to avoid detection. The behavioral changes observed will be followed up through electrophysiological investigation of the song system nuclei known to be involved with sensory evaluation and motor production.

鸟鸣系统与人类语音的发展和维持有许多相似之处。和人类一样，鸟类依靠听到自己的声音来发出声音。该提案的主要目标是测试鸟类在听觉反馈改变时是否能够调整它们的发声并表征这些行为变化的神经基础。这将通过录制鸟儿的歌声并大声播放来测试每当鸟儿唱出特定的声音模式时，就会爆发出白噪音。白噪声的播放针对歌曲的特定片段会引发听觉错误信号。为了减少这个误差信号，鸟可以停止唱目标声音或改变该声音的频谱结构以避免检测。观察到的行为变化将通过电生理学研究进行跟踪已知参与感觉评估和运动产生的歌曲系统核。
