Light and electronmicroscopic studies have been made on retinal structures in the lamprey labeled by horseradish peroxidase injected into the peripheral end of the cut optic nerve or to the midbrain tectum. On total retinal preparations, labeled axons were revealed together with dendrites and ganglionic cell bodies, as well as branching (presumably retinopetal) fibers, fine endings of which come closely to the labeled dendrites of the ganglionic cells. Electron microscopic data indicate that the labeled terminations of afferent fibers from synapses with both labeled and unlabeled dendrites, as well as with unlabeled neuronal bodies. It is concluded that centrifugal fibers in lamprey retina form contacts with the bodies and dendrites of the amacrine cells and dendrites of the ganglionic cells. Results of intracellular registration of responses of various retinal elements to the electrical stimulation of the optic nerve support this conclusion.
对七鳃鳗视网膜结构进行了光镜和电镜研究，这些视网膜结构是通过将辣根过氧化物酶注入切断的视神经外周端或中脑顶盖进行标记的。在整个视网膜标本上，可观察到标记的轴突以及树突和神经节细胞体，还有分支（可能是向视网膜的）纤维，其细小终末与神经节细胞的标记树突紧密相邻。电镜数据表明，传入纤维的标记终末与标记和未标记的树突以及未标记的神经元体形成突触。得出的结论是，七鳃鳗视网膜中的离心纤维与无长突细胞的胞体和树突以及神经节细胞的树突形成接触。对各种视网膜成分对视神经电刺激反应的细胞内记录结果支持了这一结论。
