摘要
将CB—HRP溶液电泳法引入鸡的孤束核，顺行追踪孤束核向脑干投射的神经元。结果于延髓的小细胞网状结构、三叉神经降束核、下橄榄核，中介核、前庭降核、前庭内侧核；脑桥的三叉神经运动核，三叉神经感觉主核、蓝班、臂旁核内侧部、浅部、背外侧部、腹外侧部、面背核；中脑的浅综脑核；丘胸前背内侧核等处出现明显的标记终末．此外，也在对侧的孤束核，双侧的舌下神经背核，耳蜗板核，上橄榄核，丘脑下部室旁区域等处发现少量疏淡的标记终末．
By iontophoretically applying of CB—HRP (Chalera taxin B—Chain conjugation to horseradish perioxidase) into the left solitary necleus, the present experiment studied the efferent projection to the brain stem in chicken. The labeled terminals appeared bilaterally in the medular oblongata's parvocellular reticular necleus (Rpc ), the trigeminal descending necleus, the caudal olivary necleus, the intercalary neclers, the descending vestibular necleus. the medial vestibular necleus. In the pens, it appeared bilaterally in the trigeminal motor complex, the priacipal sensory trigeminal necleus,the coceruleus locus,the parpbranchial complex,the dorsal facial motor necleus. In the midbrain, they appeated in the anterior dorsamedial necleus. Additionally,a little amount of labeled terminals cauld be found in the contrilateral selitary necleus, the dorsal hypoglossal necleus. the cochlear familiar necleus, the rostral olivary necleus, the periventricular area of the hypothalamus.
