The aim of the present work was to study the structure of the dendritic tree of the main groups of neurons in the posterior zone of the amygdaloid body and to analyze their quantitative characteristics. Frontal sections of rat brain impregnated with Golgi silver nitrate were used to study the characteristics of neuronal organization. Classification of neurons was based on criteria developed by Leontovich (1978) and Polyakov (1973). The main groups of neurons were long-axon, rarely branched cells, long-axon, densely branched subcortical cells, and long-axon, densely branched cortical cells. Quantitative studies of seven measures of the dendrite tree showed that the most informative parameters for differences between the main groups of neurons were the number of branching points and the number of free dendrite tips. The contents of rarely and densely branched neuron systems in the nuclei, paleocortex, and intermediate formations are described.
本研究的目的是研究杏仁体后部主要神经元群树突树的结构，并分析其定量特征。采用硝酸银浸染的大鼠脑额叶切片来研究神经元组织的特征。神经元的分类基于列昂托维奇（1978年）和波利亚科夫（1973年）制定的标准。主要的神经元群为长轴突、极少分支的细胞，长轴突、密集分支的皮质下细胞，以及长轴突、密集分支的皮质细胞。对树突树的七项测量指标进行的定量研究表明，区分主要神经元群差异的最有效参数是分支点数和游离树突末梢数。描述了核、古皮质和中间结构中极少分支和密集分支神经元系统的含量。
