Abstract

The morphology of hippocampal granule cells was studied in two species of megachiropteran bats. In general the morphological appearance of megabat granule cells corresponded to that of other mammals. However, with respect to the regular presence of basal dendrites the majority of granule cells resembled their counterparts in primates, but differed from rodents and carnivores where basal dendrites are absent in adults. Due to the laminar segregation of hippocampal afferents basal dendrites are presumed to be functionally significant by receiving synaptic input from projections to the hilar region.

摘要

在两种大型翼手目蝙蝠中研究了海马颗粒细胞的形态。总体而言，大型蝙蝠颗粒细胞的形态外观与其他哺乳动物的相似。然而，就基底树突的普遍存在而言，大多数颗粒细胞类似于灵长类动物中的对应细胞，但与成年后不存在基底树突的啮齿动物和食肉动物不同。由于海马传入纤维的层状分隔，推测基底树突通过接收来自投射到海马门区的突触输入而具有功能意义。
