The richness of social stimuli shapes developmental trajectories: Are laboratory mouse pups impoverished?
Shaping brain development: Mouse communal nesting blunts adult neuroendocrine and behavioral response to social stress and modifies chronic antidepressant treatment outcome
Early interactions with mother and peers independently build adult social skills and shape BDNF and oxytocin receptor brain levels
Birth spacing in the mouse communal nest shapes adult emotional and social behavior
Early social enrichment provided by communal nest increases resilience to depression-like behavior more in female than in male mice
Social Enrichment during Postnatal Development Induces Transgenerational Effects on Emotional and Reproductive Behavior in Mice
TLDR
Analysis of neuropeptide receptor levels suggest that a communal rearing environment may exert sustained effects on behavior through modification of oxytocin and vasopressin (V1a) receptor densities.
Communal nesting exerts epigenetic influences on affective and social behaviors in rats selectively bred for an infantile trait
Early social enrichment affects responsiveness to different social cues in female mice
Epigenetic modifications induced by early enrichment are associated with changes in timing of induction of BDNF expression
Chapter 10 Epigenetic Influence of the Social Environment
TLDR
There is emerging evidence supporting the hypothesis that epigenetic changes, such as DNA methylation and histone modifications, may mediate the effects of early life variations in the social interactions between mothers and infants and that the social experiences of juveniles and adults may also induce epigenetic change.

TLDR
Findings show that CN, an highly stimulating early social environment, increases adult neuronal plasticity, as suggested by high BDNF levels and augmented number of newly generated cells in the hippocampus, which is associated to an increased anxiety‐ and “depression”‐like behavior.
