摘　　要：实验材料为乌拉坦麻醉的鸣禽黄雀（Ｃａｒｄｕｅｌｉｓｓｐｉｎｕｓ）。观察了电及化学刺激新纹状体前部大细胞核外侧部（ｌＭＡＮ）对发声和呼吸的影响。结果如下：（１）电刺激ｌＭＡＮ的不同区域都引起鸣叫反应。（２）长串电脉冲刺激ｌＭＡＮ使呼吸频率增加，呼吸幅度降低。（３）短串电脉冲刺激ｌＭＡＮ，落位于吸气相，产生吸气切断效应；落位于呼气相，可使呼气时程延长，以配合鸣叫。（４）微量注射乙醇，呼吸出现先抑制后增频增幅的交替变化。提示ｌＭＡＮ除对发声有调控作用外，对呼吸也有一定的影响，这种影响可能在鸣叫与呼吸的协调机制中起一定的作用。Experiments on urethane-anesthetized Carduelis spinus were performed The effects of electrical and chemical stimulation to the nucleus lateral magnocellularis of anterior neostriatum (lMAN) on vocalization and respiration were observed The results were as follows: (1) Electrical stimulation of lMAN caused vocal response (2) Long train electrical stimulation of lMAN elicited an increase of respiratory rate and a reducing of respiratory depth (3) Short train stimulation administered in lMAN during the inspiratory and expiratory phase terminated the inspiratory switch-off and prolongation of expiratory phase so as to coordinate vocalization (4) Microinjection of ethanol into lMAN produced an alternate change of the respiratory inhibition first, and then increase of respiratory rate and depth These results showed that lMAN had some effects on respiration besides vocal control This suggested that lMAN might take a part in coordinating singing and respiration
