摘　　要：以成年雄性斑胸草雀为研究对象,去势后成年雄鸟鸣曲空间结构显著改变,平均频率和峰频率下降,主题曲相似度降低,鸣曲稳定性下降;损毁LMAN后,平均频率、峰频率、主题曲相似度都恢复到去势前水平.去势引起鸣曲结构和稳定性变化.损毁LMAN逆转鸣曲的变化表明LMAN对雄激素(睾酮)调节鸣曲变化至关重要.Adult male zebra finches were castrated and the song was acoustic analyzed. It was found that the spatial structure of birdsong changed significantly,the mean frequency,peak frequency and similarity of the motifs decreased,the stability of song decreased after castration. Castrating-induced song changes of structure and stability were reversed by LMAN lesion,suggested that LMAN contributes to the effect of testosterone on song regulation.
