After reviewing the loci of origin for neurons with collateralized axons, some hypotheses on their distribution in the mammalian nervous system, on their functional contributions and on their significance in the course of encephalization are discussed. In principle, the distribution of collateralized neurons seems to be restricted to anatomical circuits subserving unspecific activation of forebrain regions and controlling body balance and movements. Concerning the limbic system, a minor degree of collateralization seems to exist only in less encephalized species. Based on a number of anatomical and functional arguments, it is assumed that the significance of collateralization fades in the course of encephalization.
在回顾了具有分支轴突的神经元的起源位点后，讨论了关于它们在哺乳动物神经系统中的分布、它们的功能贡献以及它们在脑进化过程中的意义的一些假说。原则上，具有分支的神经元的分布似乎仅限于那些为前脑区域的非特异性激活以及控制身体平衡和运动服务的解剖学回路。关于边缘系统，似乎只有在脑进化程度较低的物种中才存在轻微程度的分支。基于一些解剖学和功能方面的论据，人们假定分支的意义在脑进化过程中逐渐消失。
