Abstract
Volumetric estimates of the total number of granule cells in rats 30, 120, 200, and 365 days old increase linearly by approximately 35 to 43 percent between 1 month and 1 year. Total volume of the granular layer also grows linearly during that time. These results demonstrate a numerical increase in a neuronal population during adulthood in the mammalian brain.
摘要
对30日龄、120日龄、200日龄和365日龄大鼠颗粒细胞总数的体积估计显示，在1个月至1年期间，颗粒细胞总数呈线性增加，增幅约为35%至43%。在此期间，颗粒层的总体积也呈线性增长。这些结果表明，哺乳动物大脑在成年期神经元数量会增加。
