In view of the contradictory results obtained from a number of studies on the nature of ring images found after neurofibrillar silver impregnation, this question was reinvestigated at the ultrastructural level in the lateral geniculate nucleus of the monkey. The ring images found here are produced by silver deposits on ring-shaped accumulations of neurofilaments in the afferent synapses of retinal origin. Tubular impregnation of axons was not found to be a factor in the genesis of ring images.
鉴于在一些关于神经原纤维银浸染后发现的环状图像性质的研究中得到了相互矛盾的结果，在猴子外侧膝状核的超微结构水平上对这个问题进行了重新研究。这里发现的环状图像是由银沉积在视网膜起源的传入突触中神经丝的环状聚集体上产生的。未发现轴突的管状浸染是环状图像形成的一个因素。
