This study shows that early life adversity increases prosocial helping behavior in rats and is associated with changes in brain-wide neural activity and network organization.

This study investigates how early life adversity in mice affects reward processing and behavior, finding altered dopamine dynamics and behavioral opportunism.

This study shows that chronic stress alters Pnoc expression in reward-related brain regions and that NOPR antagonism improves reward learning and motivation in animals and humans.

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.

This study shows that early life adversity affects stress responses and social behavior in mice, with sex-specific changes in corticosterone levels and social interactions following stress.

This study shows that region-specific gray matter myelin changes in rats and humans correlate with stress-induced behavioral differences, suggesting a common mechanism across species.

The paper shows that adolescent rats help both ingroup and outgroup members, while adults show ingroup bias, with neural activity differences in brain regions like the hippocampus and orbitofrontal cortex.

This study shows that juvenile stress alters grey matter myelination in adult female rats but not males, highlighting sex-specific vulnerability during peri-adolescence.
