In anesthetized adult rabbits, the responses of pial and precortical arteries to retinal photostimulation and the application of 0.5% strychnine solution to the brain surface were studied, as well as the distribution of cholinergic and adrenergic nerve fibres in these microvessels. The precortical arteries showed the highest degree of dilatation and frequency of responses. Dense innervation was mostly in evidence in the precortical arteries. Upon atropin application, the response suppression was also more obvious in the precortical arteries. The data suggest that the precortical arteries play an important role in regulation of the adequate blood supply to the brain tissue.
在麻醉的成年兔中，研究了软脑膜动脉和皮质前动脉对视网膜光刺激以及在脑表面应用0.5%士的宁溶液的反应，以及这些微血管中胆碱能和肾上腺素能神经纤维的分布。皮质前动脉显示出最高程度的扩张和反应频率。密集的神经支配主要在皮质前动脉中可见。应用阿托品后，皮质前动脉的反应抑制也更明显。数据表明，皮质前动脉在调节脑组织充足血液供应中起重要作用。
