The main focus of this research program is to study the links between brain and behaviour when songbirds listen to vocalizations from their own species. Like humans learn speech, songbirds learn their vocalizations: young male songbirds must hear  adult males sing in order to produce accurate song as adults. Males also listen to other males when defending territory. Females listen to male song for mate choice. Both sexes also have specific regions in the brain that are active when birds listen to song and other vocalizations. However, compared to song learning  and production in males, perception of vocalizations in general and any seasonal plasticity in perception or neural regions has  been studied far less, especially in females. My research program will examine both behavioural and neural aspects of perception of conspecific vocalizations. To do this, I will look at activity in neural regions associated with listening to song when birds are exposed to playback of various stimuli.  Since these stimuli are usually vocalizations from other birds, I will also be recording vocalizations from all birds that come into the laboratory.  To perform these experiments and obtain clean recordings, I require 4 soundproof booths to house the birds while participating in experiments. This research will provide a more complete picture of seasonality in brain and behaviour in songbirds by providing information on perception, a previously neglected area of research.

这项研究计划的主要重点是研究鸣禽在聆听自己物种的声音时大脑和行为之间的联系。就像人类学习语言一样，鸣禽也学习发声：年轻的雄性鸣禽必须听到成年雄性的歌唱，才能像成年鸟一样发出准确的歌声。雄性在保卫领土时也会听从其他雄性的意见。雌性听雄性的歌来选择配偶。两性大脑中也有特定的区域，当鸟类听到歌曲和其他声音时，这些区域会活跃起来。然而，与男性的歌曲学习和生产相比，对一般发声的感知以及感知或神经区域的任何季节性可塑性的研究要少得多，特别是在女性中。我的研究计划将检查行为和神经方面的感知同种发声。为了做到这一点，我将观察当鸟类暴露在各种刺激的回放中时，与听歌相关的神经区域的活动。由于这些刺激通常是来自其他鸟类的声音，我也将记录所有进入实验室的鸟类的声音。为了进行这些实验并获得清晰的录音，我需要4个隔音隔间来容纳参与实验的鸟类。这项研究将提供一个更完整的图片的季节性大脑和行为的鸣禽通过提供信息的感知，以前被忽视的研究领域。
