在猫外侧膝状核（LGN）的高尔基浸染中，分析了III类、高尔基II型神经元的形态特征，特别注意了这些细胞的复杂树突附属物，即多叶树突终末。此外，电镜研究表明突触前树突（ID）终末是突触肾小球的主要组成部分。连续薄片的电子显微镜分析证实了这些末端的枝晶起源和复杂的多叶性质。我们提出了一种假设，将ID终端与光镜下鉴定的III类细胞的多叶树突状终端相鉴别，而将IA终端（肾小球的“外周轴突”）与所有高尔基II型细胞的轴突末梢相鉴别。
The morphological characteristics of Class III, Golgi Type II neurons are analyzed in Golgi impregnations of the lateral geniculate nucleus (LGN) in the cat with special attention given to the complex dendritic appendages of these cells, the multilobed dendritic terminals. In addition, electron microscopic studies demonstrate the presence of presynaptic dendritic (ID) terminals as major components of synaptic glomeruli. Electron microscopic analysis of serial thin sections confirm the dendritic origin and the complex, multilobed nature of these terminals. An hypothesis is proposed identifying the ID terminal with the multilobed dendritic terminals of light microscopically identified Class III cells and the IA terminal, the “peripheral axon” of the glomerulus, with the axonal endings of all Golgi Type II cells.
