Using conventional electron microscopic techniques, we examined the sympathetic axons that invade the rat hippocampal formation following cholinergic denervation. We found fascicles of unmyelinated axons adjacent to parenchymal blood vessels. These fascicles were separated from the surrounding neuropil by a duplication of basal lamina. These results suggest that specific morphological changes accompany the invasion of the central nervous system by peripheral axons.
运用传统电子显微镜技术，我们检查了胆碱能去神经支配后侵入大鼠海马结构的交感神经轴突。我们发现无髓鞘轴突束紧邻实质血管。这些轴突束通过基膜重复与周围神经纤维网分隔开来。这些结果表明，外周轴突侵入中枢神经系统会伴随特定的形态学变化。
