本实验用辣根过氧化物酶(HRP)法研究了大鼠脑干向小脑核的纤维投射。观察到脑干具有HRP标记神经元的核团如下:下橄榄核、外侧网状核、脑桥被盖网状核、桥核、三叉神经脊束核、三叉神经感觉主核、三叉神经中脑核、前庭神经脊核、前庭神经内侧核、延髓腹侧网状核、延髓巨细胞网状核、延髓旁正中网状核、中缝桥核、中缝隐核、中缝大核、舌周核、兰斑核、薄束核、楔束核、楔外核。小脑各核接受脑干核团投射纤维不尽相同,其中以外侧核和间位核接受较多的脑干核团投射纤维,脑干标记核团基本相同,但有投射纤维到小脑顶核的脑干核团较少。本文讨论了橄榄小脑核投射的局部定位关系。
In this experiment, horseradish peroxidase (HRP) method to study the brain stem to the cerebellar nuclear projection. The nuclei of brainstem with HRP-labeled neurons were observed as follows: inferior olivary nucleus, lateral reticular nucleus, reticular nucleus covered by pons, nucleus of nucleus accumbens, nucleus of trigeminal nucleus, nucleus of trigeminal sensory nucleus, mesencephalic nucleus of trigeminal nerve Vestibular nerve nucleus, medial vestibular nucleus, medulla oblongata reticular nucleus, medulla oblongata giant cell reticular nucleus, medulla oblongata median reticular nucleus, Nuclear, thin beam nuclear, wedge beam nuclear, wedge outer core. The cerebellar nuclei receive brainstem nuclei projection fiber varies, including the lateral nucleus and the intervening nucleus to accept more brain stem nuclei projection fibers, brain stem labeled nuclei are basically the same, but the projection of fibers to the cerebellar fastigial nucleus Less brainstem nuclei. This article discusses the local localization of olive cerebellar projection.
