The blood vessels of the cerebellar cortex were studied by two methods of injection: india-
ink and low viscosity resin (Mercox). The study is divided into two parts: 1.(a) Pial vessels;
few in number at the cerebellar surface, the pial vessels are quite dense, forming vascular
laminae, within the sulci. Pial vessels do not frequently anastomose, 2.(b) Intracortical
vessels closely resemble those of the cerebral cortex. They may be divided into three
categories: short, middle and long. There exist three vascular layers within the cerebellar …
