This study examines sex differences in behavioral and neuroendocrine responses to aggression in California mice, finding that females show increased freezing behavior and males show increased vasopressin-c-fos co-localization after repeated aggression.

Oxytocin, but not vasopressin, decreases willingness to harm others by promoting moral emotions of guilt and shame

This study shows oxytocin, but not vasopressin, reduces willingness to harm others by increasing guilt and shame for intentional harm.

Helping behavior is associated with increased affiliative behavior, activation of the prosocial brain network and elevated oxytocin receptor expression in the nucleus accumbens

The paper identifies behavioral, neural, and molecular differences between rats that help and those that do not in a distress test, linking prosocial behavior to affiliative behavior and oxytocin receptor expression.

Group social dynamics in a semi-natural setup reveal an adaptive value for aggression in male mice

The paper studies aggression and social dominance in mice using a semi-natural setup, finding that environmental enrichment increases aggression as an adaptive response while oxytocin receptor deficiency leads to hyper-aggression and disrupted social hierarchies.
