DESCRIPTION (provided by applicant): 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 application is to test whether birds can adapt their vocalizations when auditory feedback is altered and to characterize the neural basis for these behavioral changes. This will be tested by recording the bird's song and playing loud burst of white noise whenever the bird sings 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.

描述（由申请人提供）：鸟鸣系统与人类语音的发展和维持有许多相似之处。像人类一样，鸟类依靠听到自己的声音来发出声音。该应用程序的主要目标是测试鸟类在听觉反馈改变时是否能够适应它们的发声，并描述这些行为变化的神经基础。这将通过录制鸟儿的歌声并在鸟儿唱出特定模式的声音时播放响亮的白噪音来进行测试。针对歌曲特定片段的白噪声播放会引起听觉错误信号。为了减少这种误差信号，鸟可以停止唱目标声音或改变该声音的频谱结构以避免被发现。观察到的行为变化将通过对已知参与感觉评估和运动产生的鸣叫系统核的电生理学研究来跟踪。
