Praepyramidal and pyramidal neurons were demonstrated in homologous telencephalic areas of Salmo irideus (Gibbons 1855), Rana temporaria L., Rattus norvegicus, forma alba, by means of the Golgi-technique. A comparative morphometrical analysis was made concerning the following parameters: main dendritic length, length of the pericaryon, number of dendritic spines in the first 50-micrometer-dendritic segment and length of the spines-free zone. From these data a quotient was calculated and expressing the theoretical dendritic length per ten spines. There is an increase of length of the pericaryon, length of the spines-free zone, main dendritic length and a pseudo-decrease of the number of dendritic spines in the first 50 micrometer-dendritic segment in rats, as compared with Rana and Salmo. The results are discussed with respect to following problems: homology, phylogenesis and corticalisation.
运用高尔基染色技术，在虹鳟（吉本斯，1855年）、欧洲林蛙、挪威大白鼠等物种的同源端脑区域中，证实了锥体外系神经元和锥体神经元的存在。针对以下参数进行了比较形态计量分析：主要树突长度、胞体长度、首个50微米树突段内的树突棘数量以及无棘区长度。根据这些数据计算出一个商数，用以表示每十个树突棘的理论树突长度。与蛙类和虹鳟相比，大鼠的胞体长度、无棘区长度、主要树突长度增加，而首个50微米树突段内的树突棘数量出现假性减少。针对同源性、系统发生和皮质化等问题对结果进行了讨论。
