Quantitative morphological analysis of the number of granule cell dendritic spines, as well as total dendritic length and dendritic branching of neurons in the dentate gyrus and the nucleus of Meynert was done in 11-day-old rats after passive avoidance training in the neonatal period. Learning improved stepwise and its neuromorphological sequels were characterized by a statistically significant enhanced number of dendritic spines, due to an increase of thin spines, enhanced dendritic branching in both structures, and increased total dendritic length in the dentate gyrus compared with the controls.
对11日龄大鼠进行新生期被动回避训练后，对齿状回和Meynert核中颗粒细胞树突棘数量、神经元的总树突长度和树突分支进行了定量形态学分析。学习呈逐步改善，其神经形态学后续变化的特征是，与对照组相比，由于细棘数量增加，树突棘数量在统计学上显著增加，两个结构中的树突分支均增强，齿状回中的总树突长度增加。
