摘要
采用电刺激的方法，对鸣禽黄喉（Ｅｍｂｅｒｉｚａｅｌｅｇａｎｓ）的上纹状体腹侧尾核（ＨＶ＿Ｃ）的发声控制及其它生理功能进行了初步地研究，结果如下：１）长串或短串电脉冲刺激ＨＶ＿Ｃ的不同区域，部引起鸣叫反应．２）长串电脉冲刺激ＨＶ＿Ｃ引起呼吸易化效应：表现为增频增幅的呼吸．３）短串电脉冲刺激ＨＶ＿Ｃ引起呼吸位相转换效应及呼气时程延长效应，如刺激落位于吸气相时，可迅速转换到呼气相；刺激落位于呼气相时，可使呼气时程延长，以配合鸣叫．４）电刺激ＨＶ＿Ｃ引起明显降心率效应．５）电刺激ＨＶ＿Ｃ引起明显的竖毛、瞳孔缩小及躯体运动等反应．结果表明，ＨＶ＿Ｃ除控制发声外，尚参与呼吸易化和降心率的调节．ＨＶ＿Ｃ对发声及呼吸的特异性调节作用，可能在鸣叫与呼吸的协调机制中起重要的作用．此外，ＨＶ＿Ｃ亦参与植物性及情绪性反应的调节．
The vocal control and other phsiological functions of the hyperstriatum ventrale,pars caudale (HV_C)in Emberiza elegans were studied using electrical stimulating methods.The results were as follows:1)Long or short train electrica pulses stimulating different area of HV_C caused vocal response.2)Long train electrical pulses stimulating HV_C caused respiratory facilitating effects:increase of respiratory rate and depth.3)Short train electrical pulses stimulating HV_C caused inspiratory off-switch and a short lengthening of expiratory time,furthermore coordinating vocalizatians. 4)Electical stimulating HV_C caused standing of feathers,reducing heart rate. 5)Electrical stimulating HV_C caused standing of feathers, reducing of pupilla and moving of sensation. The results indicate that HV_C may be involved in the regulations of respiratory facilitating effects and bradycardia besides vocal control. And HV_C had exceptional effect to vocalization and respiration.It is suggested that HV_C may take an important part in coordinating song and respiration.Moreover HV_C also maybe involved in the regulations of vagetative and emotional functions.
