摘　　要：哺乳动物大脑伴随个体从出生到成熟,衰老、死亡处于动态发展中,受到先天遗传因素和后天环境因素影响。其中遗传因素相对易于作为共性或特征进行研究,但是后天环境复杂多变。环境因素影响大脑对认知、情感、社会交往等行为的调控,其影响程度和机制尚未完全清楚,本文就丰富环境对大鼠社会行为影响研究进展做概要介绍。Dynamic changes in the brain of mammals are mediated by genetic and environmental factors. The genetic factors are relatively easy to investigate as generality or characteristics objects, while environmental factors are complex. Enriched environment is known to promote structural changes in the brain and enhances cognition, emotional behaviours as well as social behaviours. However, the influence is difficult to evaluate and the mechanisms are not fully understood. To better understand the biomedical mechanisms un- derlying these experience-dependent functional and structure changes, we mainly summarize the recent advancement about this aspect.
