Mother lowers glucocorticoid levels of preweaning rats after acute threat.
Exposure to a deadly threat, an adult male rat, induced the release of corticosterone in 14-day-old rat pups. The endocrine stress response was decreased when the pups were reunited with their mother immediately after exposure. These findings demonstrate that social variables can reduce the consequences of an aversive experience.
