On hand of the electonmicroscope, the authors study 24 parts of the encephalic ventricles in samples of Bradypus tridactylus, relating the nervous structures to the ependymal lining, chiefly emphasizing the presence of intraventricular unmyelinated fibres. In various of these regions, typical nerve fibres and other intraventricular cell projections, that cannot be taken as nerve structures, because of the continuity they show along with ependymal cells, were observed. Finally they make an analysis of some functions related to arrangements of this nature.
作者在电子显微镜下研究了三趾树懒样本中脑室内的24个部位，将神经结构与室管膜内衬相关联，主要强调脑室内无髓纤维的存在。在这些区域中，观察到了典型的神经纤维以及其他脑室内细胞突起，由于它们与室管膜细胞相连续，因此不能被视为神经结构。最后，他们对与这种结构排列相关的一些功能进行了分析。
