Female zebra finches can be induced to develop a male-like song system by being exposed to a steroid as nestlings. After subsequent testosterone treatment they develop song whose quality depends on age and duration of early steroid treatment. This study compares the anatomy of two song nuclei with the birds' song quality. The capacity for song correlates with the volumes of the nucleus hyperstriatum, ventralis, pars caudalis (HVc) and the nucleus robustus archistriatalis (RA) and with the size of RA neurons.
雌性斑胸草雀在雏鸟期接触一种类固醇后，可被诱导发育出类似雄性的鸣唱系统。在随后接受睾酮治疗后，它们会发育出鸣叫，其质量取决于早期类固醇治疗的年龄和持续时间。本研究比较了两个鸣唱核团的解剖结构与鸟类的鸣叫质量。鸣叫能力与尾侧腹侧超纹状体核（HVc）和古纹状体粗核（RA）的体积以及RA神经元的大小相关。
