Cerebellar glomeruli of simple type were studied by quantitative morphological and stereological methods. It has been found that in one glomerulus the centrally located mossy terminal forms synaptic contacts with about 50 granule cell dendrites, all deriving from distinct granule cells. The three-dimensional reconstruction of the glomeruli revealed that the terminal portion of the dendrites, the so called digits, are elongated, thin processes. Synaptic contacts by mossy terminals are established exclusively on the dendritic digits. Although these digits are the main postsynaptic targets for the Golgi axon terminals as well, these inhibitory endings might also synapse with the proximal portion of the granule cell dendrites.
采用定量形态学和体视学方法研究了简单型小脑小球。研究发现，在一个小球中，位于中央的苔藓状终末与约50个颗粒细胞树突形成突触联系，这些树突均来自不同的颗粒细胞。小球的三维重建显示，树突的终末部分，即所谓的指状突起，是细长的薄突起。苔藓状终末的突触联系仅在树突指状突起上建立。尽管这些指状突起也是高尔基轴突终末的主要突触后靶点，但这些抑制性终末也可能与颗粒细胞树突的近端形成突触。
