摘　　要：在乌拉坦麻醉的鸣禽燕雀（Ｆｒｉｎｇｉｌｌａｍｏｎｔｉｆｒｉｎｇｉｌｌａ）上，观察电刺激上纹状体腹侧尾核（ＨＶｃ）对发声和呼吸的影响，随后在ＨＶｃ内注入ＣＢ－ＨＲＰ溶液，研究ＨＶｃ的中枢联系。结果如下：（１）电刺激ＨＶｃ的不同区域都引起鸣叫反应。（２）长串电脉冲刺激ＨＶｃ，产生明显的呼吸易化效应，表现为增频增幅的呼吸。（３）吸气期用短串电脉冲刺激ＨＶｃ，产生吸气切断效应；刺激落位于呼气相，可使该呼气时程明显延长，以配合鸣叫，然后转变为增频增幅的呼吸。（４）ＣＢＨＲＰ法表明，ＨＶｃ投射到古纹状体粗核和嗅叶Ｘ区，ＨＶｃ接受新纹状体前部大细胞核内侧部、新纹状体中部界面核、端脑听核－Ｌ区、丘脑葡萄形核及脑桥蓝斑核的传入投射。提示ＨＶｃ除控制发声外，尚参与呼吸易化的调制。ＨＶｃ对发声及呼吸的特异性影响，可能在鸣叫与呼吸的协调机制中起重要作用。In urethane-anesthetized Fringilla montifringilla, effects of electrically stumulating the hyperstriatum ventrale pars caudale (HVc)on vocalization and respiration were observed. Central connections of HVc were investigated by means of injecting CB-HRP into HVc. The results were as follows:(1) Electrical stimulation of HVc caused vocal response. (2) Long train electrical pulses stimulation of HVc elicited significant respiratory facilitating effects, that is, increase of respiratory rate and depth.(3) Short train stimulation administered in HVc during inspiratory phase terminated switching-off of inspiration, and during expiratory phases produced the prolongation of expiratory phase so to coordinate vocalization and then increasing the respiratory rate and depth. (4)CB-HRP traces revealed that HVc projected to robust nucleus of the archistriatum, and atea X of lobus parolfactorius. HVc received projections from medial nucleus magnocellularis of the anterior neostriatum, nucleus interfacialis of midneostriatum, telencephalic auditory nucleus-field L, nucleus uvaeformis of the thalamus, and locus ceruleus of the pons. These results showed that, besides vocal control, HVc may be involved in neural regulations of respiratory facilitation, the effect on respiration seeming specific.It is suggested that HVc may play an important role in coordinating singing and respiration.
