鸣禽的歌曲感知，就像人类的音乐和语音感知一样，需要处理在歌曲音节序列中发现的频谱和时间结构。使用功能性磁共振成像和合成的歌曲，保留专门的时间或频谱结构的自然歌曲，我们研究了如何发声处理在鸟类前脑。我们发现双侧和平等激活的主要听觉区域，字段L。更腹侧区域的字段L表现出抑郁症的合成歌曲，缺乏光谱结构的反应。这些腹侧区域包括L3亚区、中间-腹侧亚区L和可能的次级听觉区域尾侧内侧巢皮质。此外，场L作为一个整体表现出意想不到的增加响应的时间过滤的歌曲，这种增加是最大的背侧区域。这些背侧区包括L1和背侧亚区L和L2 b。因此，腹侧区域的字段L似乎是更敏感的光谱和时间信息的保存在歌曲处理的上下文中。我们没有发现任何差异的反应，播放鸟类自己的歌曲与其他熟悉的同种歌曲。我们还研究了三种常用麻醉剂对血氧水平依赖性反应的影响：美托咪定，乌拉坦和异氟醚。激活区域的范围和刺激选择性取决于麻醉剂的类型。我们讨论这些结果的背景下，什么是已知的麻醉剂的作用位点，并在电生理实验中测量的神经活动的报告。
Song perception in songbirds, just as music and speech perception in humans, requires processing the spectral and temporal structure found in the succession of song-syllables. Using functional magnetic resonance imaging and synthetic songs that preserved exclusively either the temporal or the spectral structure of natural song, we investigated how vocalizations are processed in the avian forebrain. We found bilateral and equal activation of the primary auditory region, field L. The more ventral regions of field L showed depressed responses to the synthetic songs that lacked spectral structure. These ventral regions included subarea L3, medial-ventral subarea L and potentially the secondary auditory region caudal medial nidopallium. In addition, field L as a whole showed unexpected increased responses to the temporally filtered songs and this increase was the largest in the dorsal regions. These dorsal regions included L1 and the dorsal subareas L and L2b. Therefore, the ventral region of field L appears to be more sensitive to the preservation of both spectral and temporal information in the context of song processing. We did not find any differences in responses to playback of the bird's own song vs other familiar conspecific songs. We also investigated the effect of three commonly used anaesthetics on the blood oxygen level-dependent response: medetomidine, urethane and isoflurane. The extent of the area activated and the stimulus selectivity depended on the type of anaesthetic. We discuss these results in the context of what is known about the locus of action of the anaesthetics, and reports of neural activity measured in electrophysiological experiments.
