Environmental Enrichment Reverses the Effects of Maternal Separation on Stress Reactivity
Open accessAbstract
Postnatal maternal separation increases hypothalamic corticotropin-releasing factor (CRF) gene expression and hypothalamic-pituitary-adrenal (HPA) and behavioral responses to stress. We report here that environmental enrichment during the peripubertal period completely reverses the effects of maternal separation on both HPA and behavioral responses to stress, with no effect on CRF mRNA expression. We conclude that environmental enrichment leads to a functional reversal of the effects of maternal separation through compensation for, rather than reversal of, the neural effects of early life adversity.

In the citing paper
“Environmental enrichment has been shown to successfully reverse several ELS-induced impairments in behavior, including learning and memory, anxiety, depressive-like behavior, and attention (Francis et al., 2002; Cui et al., 2006; Vivinetto et al., 2013; Zubedat et al., 2015; Koe et al., 2016).”

Experimental — accuracy not yet measuredIn the citing paper
“Studies in humans and animals models show that environmental enrichment can reduce or reverse some of the effects of deprivation, non-normative stimulation and even acute or chronic stress [122,123] at the behavioural and neural levels [109,[124][125][126].”
In the citing paper
“For example, Francis, Diorio, Plotsky, and Meaney (2002) demonstrated reversal of the effect of early stress associated with maternal separation during the neonatal period on the HPA response to stress, as indicated by corticosterone levels, and on learning and memory among rats receiving environmental enrichment.”

In the citing paper
“Effects on corticosterone and behavior, however, could not be attributed to expected changes at the neural level in terms of primary processes that influence stress reactivity.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
