摘    要:用生物素示踪法和P物质(SP)免疫组化技术研究表明:黄喉(巫鸟)的高级发声中枢(HVc)接受端脑听区(L)、新纹状体中部界面核、新纹状体巨细胞核(MAN)、丘脑葡萄形核、桥脑蓝斑核的传入,并有神经纤维投射到古纹状体栎核(RA)和嗅叶X区(X);HVc壳投射到RA壳并接受L的传入.听觉控制与学习通路与发声中枢之间有许多神经联系,提示黄喉(巫鸟)发声学习依赖于听觉反馈.在HVc、RA和MAN有SP阳性细胞体,在X、中脑背内侧核和延髓舌下神经核气管鸣管部、丘脑卵圆核壳区、中脑背外侧核壳区及中脑丘间核有SP阳性纤维和终末.SP广泛分布于发声-听觉中枢,可能参与了它们的活动.

关 键 词:黄喉(巫鸟)  发声核团  听觉中枢  神经投射  P物质

Abstract:Using the neural tracer biotinylated dextran amine and the immunohistochemical methods,we found that high vocal center (HVc) in Emberiza elegans received projections from the auditory area field (L),nucleus interfacialis of midneostriatum,magnocellular nucleus of the anterior neostriatum (MAN),nucleus uvaeformis,and locus ceruleus of pons;HVc projected to the robust archistriatum (RA) and area X of lobus(X).HVc shell projected to the RA cup and received from L.As there were many neural connections among the vocal control and learning pathway,and the auditory center,vocal learning may depend on a feedback of listening senses.Substance P (SP) labeled neurons distributed in HVc,RA and MAN.SP labeled fibers and terminals distributed in X,the nucleus dorsalis medialis,the nucleus hypoglossi,pars tracheosyringealis,the nucleus ovoidalis shell,the shell of mesencephalicus lateralis,pars dorsalis,and the nucleus intercollicularis.SP widely distributed in vocal auditory centers,and may involve in their activities.
Keywords:Emberiza elegans  Vocal nucleus  Auditory center  Nervons projection  Substance P
