本文讨论的分布的轴突产生在筋膜齿状回和去海马适当。将损伤置于齿状筋膜中，并通过银浸渍绘制退化的苔藓纤维，主要根据Fink和Heimer（'67）的方法。大鼠的齿状筋膜和苔藓纤维层形成一个弯曲和扭曲的结构，从隔的后面的水平延伸到颞尖。因此，本研究所用的水平连续切片部分通过三维重建来解释，苔藓纤维在任何点都不进入菌毛。退化的纤维可以追溯到区域上级（CA 1）和区域下级之间的界限。这种齿状回-海马连接显示出精确定位的模式，每个水平的齿状筋膜投射到一个有限的下区域水平。在筋膜齿状损伤产生的退化苔藓纤维带主要是在横向方向（略在颞方向），并在远端比在从门的起源有点宽。在少数病变特别小的动物中观察到非常窄的条带。
The paper deals with the distribution of the axons that arise in the fascia dentata and go to the hippocampus proper. lesions were placed in the fascia dentata and degenerating mossy fibers were mapped by silver impregnation, mostly according to the method of Fink and Heimer ('67). The fascia dentata and the layer of mossy fibers in the rat form a curved and twisted structure extending from the level of the posterior aspect of the septum to the temporal tip. The horizontal serial sections used for this study were, therefore, in part interpreted by means of three‐dimensional reconstructions.Mossy fibers do not enter the fimbria at any point. Degenerating fibers can be traced to the limit between regio superior (CA 1) and regio inferior. This dentato‐hippocampal connection displays a pattern of precise localization, each level of fascia dentata projecting onto a restricted level of regio inferior. The bands of degenerated mossy fibers produced by lesions in the fascia dentata were largely oriented in the transverse direction (slightly in a temporal direction) and were somewhat wider distally than at the origin from the hilus. Very narrow bands were seen in a few animals with particularly small lesions.
