The arterial structure of the cerebellar cortex was studied by vascular stain and in diaphanized specimens after intra-arterial barium injections. A scanning electron microscope study on the corrosion cast of the arteries was also performed. Arteries distributed in the cerebellar hemisphere are classified into cortical, subcortical, and medullary arteries. The patterns of arterial distribution are similar to those in the cerebral cortex. The cortical arteries are subclassified into superficial, middle, and deep cortical branches. The superficial branches are very fine, forming capillary networks in the molecular layer. The middle cortical branches terminate in the Purkinje cell layer, by dividing into several branches extending parallel to the plane of this layer. These branches connect with capillaries in both the molecular and the granular layers. The deep cortical branches give off some collaterals along the Purkinje cell layer and terminate in the granular layer, by breaking up into capillary networks. The Purkinje cell layer is marked by arterial branches ramified from the middle and deep cortical branches and no particular dense capillary networks are formed in the Purkinje cell layer. The brains of older patients show intertwining of the middle and deep cortical branches, some forming "rope-like" appearance. These patterns are similar to those seen in the cerebral cortex, but they were found, in older people, in the cerebrum.
通过血管染色以及动脉内注射钡剂后制成的透明标本，对小脑皮质的动脉结构进行了研究。还对动脉铸型进行了扫描电子显微镜研究。分布于小脑半球的动脉分为皮质动脉、皮质下动脉和髓质动脉。动脉分布模式与大脑皮质相似。皮质动脉又细分为浅、中、深皮质支。浅支非常细小，在分子层形成毛细血管网。中皮质支在浦肯野细胞层终止，分成几条与该层平面平行延伸的分支。这些分支与分子层和颗粒层中的毛细血管相连。深皮质支沿浦肯野细胞层发出一些侧支，通过分支形成毛细血管网而终止于颗粒层。浦肯野细胞层有从中皮质支和深皮质支发出的分支，但在浦肯野细胞层没有形成特别密集的毛细血管网。老年患者的大脑中，中皮质支和深皮质支相互交织，有些形成“绳索状”外观。这些模式与在大脑皮质中看到的相似，但在老年人中，它们出现在大脑中。
