Environmental enrichment is a widely used experimental manipulation that consistently shows measurable effects on rodent behaviour across the lifespan. This scoping review assesses and thematically summarizes the literature of the past decade concerning the effects of environmental enrichment applied during sensitive developmental periods in rodent mothers and offspring. Maternal behaviours as well as maternal and offspring anxiety- and depressive-like behaviours are considered. Relevant terms were searched across five databases (Embase, MEDLINE, PsycINFO, PubMed, Web of Science) and articles were screened with inclusion and exclusion criteria. The remaining articles were thematically analysed. Our results suggest that a greater number of articles reviewed the impacts of environmental enrichment on offspring anxiety-like behaviour (n = 23) rather than on depressive-like behaviour (n = 11) or maternal caregiving behaviour (n = 12). Maternal anxiety- (n = 4) or depressive-like (n = 2) behaviours are not often evaluated for in enrichment studies. The main behavioural tests of anxiety that were reviewed include the elevated plus-maze, the open field test, and the light-dark box whereas those for depression included the forced swim test and the sucrose preference test. Our results yielded mixed findings and significant variation in behavioural responses across all tests. In mothers, trends of increased maternal care behaviours and decreased maternal depressive-like behaviours in enriched mothers were appreciated. Enrichment during the gestational period was identified as pivotal to creating behavioural change in mother subjects. In enriched offspring rodents, a trend towards decreased anxiety-like behaviours was observed most often. Potential confounds inherent in enrichment paradigms and relevant theories of enrichment and their relation to rodent behavioural tests are discussed.

环境富集是一种广泛使用的实验手段，在整个生命周期中始终显示出对啮齿动物行为的可测量影响。这项范围回顾性评估评估并主题总结了过去十年中有关在啮齿动物母亲和后代在敏感发育时期施加的环境富集的影响的文献。孕产妇的行为以及孕产妇和后代的焦虑和抑郁样行为都被考虑在内。在五个数据库（Embase，MEDLINE，PsycINFO，PubMed，Web of Science）中搜索了相关术语，并使用纳入和排除标准筛选了文章。其余文章进行了主题分析。我们的结果表明，更多的文章回顾了环境富集对后代焦虑样行为的影响（n  = 23），而不是抑郁症样行为（n  = 11）或产妇护理行为（n  = 12）。产妇焦虑症-（n = 4）或类似抑郁症（n = 2）的行为在富集研究中并不经常评估。审查的主要焦虑行为测试包括升高的迷宫，开放视野测试和明暗框，而用于抑郁症的行为测试包括强迫游泳测试和蔗糖偏爱测试。我们的结果得出的结论参差不齐，并且所有测试的行为反应均存在显着差异。在母亲中，对有经验的母亲中增加产妇护理行为和减少产妇抑郁样行为的趋势表示赞赏。孕期的充实被确定为对母亲受试者产生行为改变的关键。在丰富的后代啮齿动物中，最经常观察到一种减少焦虑样行为的趋势。
