Abstract

Background Early experiences produce persistent changes in brain and behavioral function. We investigate whether being reared in a communal nest (CN), a form of early social enrichment that characterizes the natural ecological niche of many rodent species including the mouse, has effects on adult social/aggressive behavior and nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) levels in mice.Methods The CN consisted of a single nest where three mothers kept their pups together and shared care-giving behavior from birth to weaning (postnatal day 25).Results Compared to standard laboratory conditions, in CN condition, mouse mothers displayed higher levels of maternal care. At adulthood, CN mice displayed higher propensity to interact socially and achieved more promptly the behavioral profile of either dominant or subordinate male. Furthermore, CN adult mice showed higher NGF levels, which were further affected by social status, and higher BDNF levels in the brain.Conclusions Our findings indicate that CN, a highly stimulating early social environment, produces differences in social behavior later in life associated with marked changes of neurotrophin levels in selected brain areas, including hippocampus and hypothalamus.

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.
