摘要
本实验用10只大白鼠,于脊髓颈膨大处背侧中线右侧,多点注射50%辣根过氧化物酶生理盐水溶液,总量为1.2微升。在脑干和小脑内看到数量不等的HRP标记神经元,分别位于:1.中脑:中线核、中缝背核、黑质、红核、楔核、上丘核、艾-维氏核、达克谢维奇核、Cajal中介核、被盖腹侧核和被盖背侧核。2.脑桥:中缝大核、正中中缝核、三叉神经感觉主核、外侧丘系核、脑桥吻侧网状核、脑桥尾侧网状核、蓝斑、蓝斑下核、前庭外侧核、前庭内侧核、旁臂核和上橄榄核。3.延髓:中缝苍白核、中缝暗核、薄束核、楔束核、三叉神经脊束核、孤束核、Cajal连合核、Meessen-Olszewski氏外侧网状核、旁正中网状核、巨细胞网状核和下橄榄核。4.小脑:小脑内侧核和小脑外侧核。并对中缝核、网状核、蓝斑、黑质及被盖背侧核所发出的投射到脊髓的纤维的功能意义进行了讨论。
The efferent projections to the spinal cord from the brain stem were studied with HRP.Fifty per cent solution of HRP was slowly injected into the intumescentia cervicalis at six points on its right side in 10 albino rats and the HRP-labelled cells were found in the following nuclei:1.Of the midbrain:the nucleus linearis,nucleus raphe dorsalis,substantia nigra,nucleus ruber,nucleus cuneiformis,nucleus colliculus superior,nucleus Edinger-Westphal,nucleus Darkschewitsch,nucleus interstitialis(Cajal),nucleus ventralis tegmenti and nucleus dorsalis tegmentalis;2.Of the ports:the nucleus raphe magnus,nucleus medianus raphe,nucleus trigemini principalis,nucleus lemnisci lateralis,nucleus reticularis pontis oralis,nucleus reticularis pontis caudalis,locus ceruleus,nucleus subceruleus,nucleus vestibularis lateralis,nucleus vestibularis medialis,nucleus parabrachialis and nucleus olivaris su-perior;3.Of the medulla oblongata:the nucleus raphe obscurus,nucleus raphe pallidus,nucleus gracilis,nucleus cuneatus,nucleus tractus spinalis nervi trigemini,nucleus tractus solitarius,nucleus commissuralis(Cajal),nucleus reticularis lateralis,nucleus reticularis paramedianus,nucleus reticularis gigantocellularis and nucleus olivaris inferior;4.Of the cerebellum:the nucleus medialis and lateralis.The functions of spinal projection from the nuclei raphe,reticularis,locus ceruleus,substantia nigra and the nucleus dorsalis tegmentalis have been discussed.
