摘要将辣根过氧化物酶(HRP)应用于日本七鳃鳗松果体束的横断端。除神经节细胞外，两种细胞均可见不同的HRP反应产物。第一种类型的细胞向松果体腔内伸出一个类似旋钮的突起。这种类型的细胞被电子显微镜清楚地鉴定为光感受器细胞；其外节通过感觉纤毛与椭圆形相连。另一类细胞位于感光细胞和支持细胞之间。这些细胞突起细长，明显不代表感光细胞、支持细胞或常规神经节细胞。结果表明，在七鳃鳗中，松果体的一些感光细胞向后连合投射轴突，但也有另一种类型的细胞显示长轴突投射。含有HRP的细胞随机分布于松果体，偶尔也可见于松果体旁。
SummaryHorseradish peroxidase (HRP) was applied to the transected end of the pineal tract of the lamprey, Lampetra japonica. Distinct reaction products of HRP were observed in 2 types of cell other than ganglion cells. The first type of cell protrudes a knob-like process into the pineal lumen. This type of cell was clearly identified by electron microscopy as a photoreceptor cell; its outer segment was connected to the ellipsoid through a sensory cilium. The other type of cell was located among photoreceptor and supporting cells. The processes of these cells were thin and slender, and they obviously did not represent photoreceptor, supporting, or conventional ganglion cells. The present results indicate that, in the lamprey, some of the photoreceptor cells of the pineal organ project their axon-like processes toward the posterior commissure, but that there is also another type of cell displaying long axonal projections. HRP-containing cells were distributed randomly over the pineal organ and were occasionally also observed in the parapineal organ.
