In the present study, using a systematic recording method and a variety of stimuli, we determined the proportion of responsive sites and their response features in the vocal control nucleus HVC of awake-restrained starlings, a species with multiple song types. Responsive sites were classified into three groups, according to the number of stimuli to which they responded. Sites in the three groups showed responses to individual-specific songs, with sites in the group that showed responses to only one stimulus responding mostly to a bird's own song. In comparison, very few sites exhibited responses to universal species-specific songs and to artificial nonspecific sounds. By contrast, data obtained in the same birds under urethane anesthesia show that, although the total proportion of responsive sites was similar, numerous responses to a universal species-specific song and to an artificial nonspecific pure tone could be observed.
在本研究中，我们采用系统记录方法和多种刺激手段，确定了清醒且受限的椋鸟（一种具有多种鸣叫类型的物种）的发声控制核团HVC中反应位点的比例及其反应特征。根据反应位点对刺激的反应数量，将其分为三组。三组中的位点对个体特异性鸣叫均有反应，其中仅对一种刺激有反应的组中的位点大多对鸟类自身的鸣叫有反应。相比之下，极少位点对通用的物种特异性鸣叫和人工非特异性声音有反应。相比之下，在相同鸟类的氨基甲酸乙酯麻醉状态下获得的数据表明，尽管反应位点的总比例相似，但可以观察到许多对通用的物种特异性鸣叫和人工非特异性纯音的反应。
