The connections of the rostral and caudal parts of the trigeminal and facial motor nuclei in the carp were studied with the horseradish peroxidase technique. Following ionophoretic peroxidase injections in these motor nuclei, retrogradely labeled cells were observed together with anterogradely labeled motor cell processes. Several cellular areas in thalamus, cerebellum and medulla oblongata were shown to project to the V and VII motor nuclei. Labeled cells were found in the inferior lobe and the glomerular complex of the thalamus. In the medulla oblongata, cells in the descending trigeminal nucleus, reticular nuclei and motor nuclei other than those injected were labeled. Besides these conspicuous projections several smaller connections were also found. These findings are discussed on their significance to respiratory function. Anterogradely labeled cellular processes constitute a relatively simple network of fiber connections between the various motor nuclei and the reticular nuclei of the brainstem. This apparently dendritic system of the bulbar motor complex shows a certain degree of similarity to the structure of the motor system in the spinal cord, and might play a role in the coordinated control of the muscular system.
采用辣根过氧化物酶技术研究了鲤鱼三叉神经和面神经运动核的吻侧和尾侧部分的联系。在这些运动核中进行离子电泳过氧化物酶注射后，观察到逆行标记的细胞以及顺行标记的运动细胞突起。结果显示，丘脑、小脑和延髓的几个细胞区域投射到三叉神经运动核和面神经运动核。在丘脑的下叶和小球复合体中发现了标记细胞。在延髓中，除注射部位外，三叉神经降核、网状核和运动核中的细胞也被标记。除了这些明显的投射外，还发现了一些较小的联系。讨论了这些发现对呼吸功能的意义。顺行标记的细胞突起在脑干的各种运动核和网状核之间构成了一个相对简单的纤维联系网络。延髓运动复合体的这个明显的树突系统与脊髓运动系统的结构有一定程度的相似性，可能在肌肉系统的协调控制中发挥作用。
