In experiments with adult rabbits the active microvascular segments located at particular sites of the minor pial arterial ramifications were investigated. These appeared as sphincters at off-shoots of the arterial branches, the precortical arteries, and the arterial microanastomoses. The sphincters and the precortical arteries were found plentifully supplied with the cholinergic and adrenergic nerves, but the innervation of the microanastomoses was not considerably different from that of the adjacent arterial branches. The nerves of the precortical arteries were in direct connection with the nerve fibers of the arterial branches located inside the cerebral cortex. The pattern of distribution and innervation of the active vascular portions in pial microvascular bed suggests the probability of a neurogenic control of the blood supply to the smallest areas of the cerebral cortex.
在对成年兔子进行的实验中，研究了位于软膜动脉分支特定部位的活跃微血管段。这些微血管段在动脉分支、皮质前动脉和动脉微吻合处的分支处表现为括约肌。发现括约肌和皮质前动脉有丰富的胆碱能和肾上腺素能神经供应，但微吻合处的神经支配与相邻动脉分支的神经支配没有显著差异。皮质前动脉的神经与位于大脑皮质内的动脉分支的神经纤维直接相连。软膜微血管床中活跃血管部分的分布和神经支配模式表明，大脑皮质最小区域的血液供应可能受神经源性控制。
