鸣管神经支对虎皮鹦鹉鸣叫声的支配

Control of Syringeal Nerve on the Vocalization in Budgerigar (Melopsittacus Undelafus)

    摘要
  • 摘要: 以虎皮鹦鹉(Melopsittacus undelafus)为材料，共有6对在舌下神经气管鸣管支(NXIIts)分别进行单侧和双侧切断处理，用声谱分析软件Wavesurfer和Sound Analysis Pro分析失去神经支配前后鸣声的声学变化.结果表明：断单侧NXIIts并不引起虎皮鹦鹉鸣声的改变，断双侧则引起虎皮鹦鹉鸣声的显著性改变，证明NXIIts在亚鸣禽鸣声的声学特性方面有重要的调控作用，且NXIIts对鸣肌的调控是双侧性的.即单侧NXIIts能控制左右两侧的鸣肌.

     

    Abstract: In this study, the unilateral and bilateral syrinx nerve (NXIIts) were resected in the budgerigar (Melopsittacus undelafus) to assess the roles of NXIIts in vocalization. Wavesurfer and Sound Analysis Pro were used to analyze presurgical and postsurgica
