投射到脑动脉的节后副交感细胞体的位置尚不清楚。使用轴突追踪技术，我们检查了蝶腭神经节（与第七对脑神经相关）和耳神经节（与第九对脑神经相关）是否包含将轴突发送到猫大脑中动脉（MCA）的核周体。将示踪剂辣根过氧化物酶（HRP：3 只猫）或麦芽凝集素（WGA：6 只猫）应用于缓释聚合物系统中的 MCA。三天后，双侧收获 SPG、耳神经节和奇迹网，并通过 TMB 方法 (HRP) 或免疫组织化学 (WGA) 进行示踪处理。在给定的动物中，在两种 SPG 中发现了大约相同数量的含有轴突示踪剂的细胞。偶尔可以看到标记的纤维延伸到翼神经中。在耳神经节和内奇迹网壁中也发现了阳性细胞。这些结果首次鉴定了投射到脑血管的副交感细胞体。
The location of the postganglionic parasympathetic cell bodies projecting to cerebral arteries is unknown. Using axonal tracing techniques, we examined whether the sphenopalatine ganglia (associated with the seventh cranial nerve) and otic ganglia (associated with ninth cranial nerve) contain perikarya which send axons to the feline middle cerebral artery (MCA). The tracers horseradish peroxidase (HRP: 3 cats) or wheat germ agglutinin (WGA: 6 cats) were applied to the MCA in a slow release polymeric system. Three days later the SPG, otic ganglia, and rete mirabile were harvested bilaterally and processed for tracer by the TMB method (HRP) or immunohistochemistry (WGA). In a given animal, approximately equal numbers of cells containing axonal tracer were found in both SPG. Labeled fibers occasionally could be seen extending into the vidian nerve. Positive cells were also found in the otic ganglia and in the walls of the internal rete mirabile. These results provide the first identification of parasympathetic cell bodies projecting to cerebral blood vessels.
