We revisited the relationship between brain anatomy and song behavior in zebra finches. Consistent with previous studies in other songbirds, we find that differences in volume of the telencephalic song control nucleus HVc is predictive of differences in repertoire size and phrase duration in zebra finches. We extend the study of brain and behavior correlations in song birds by showing that repertoire size in zebra finches can be predicted by variance in several brain nuclei, providing the first demonstration that volumetric differences across multiple components of a neural network are predictive of song behavior.
我们重新审视了斑胸草雀大脑解剖结构与鸣叫行为之间的关系。与之前对其他鸣禽的研究一致，我们发现端脑鸣叫控制核团HVC的体积差异可预测斑胸草雀的曲目大小和乐句时长差异。我们通过表明斑胸草雀的曲目大小可由多个脑核的差异来预测，扩展了对鸣禽大脑与行为相关性的研究，首次证明神经网络多个组成部分的体积差异可预测鸣叫行为。
