Pharmacologically elevating infant corticosterone (CORT) in the absence of the mother is not sufficient to disrupt subsequent social behavior with the mother. (a) Depiction of experimental procedure. (b) Pup engagement with mother in a social behavior test as a function of pharmacological manipulation (saline vs. CORT injection) during a brief separation from the mother. Data are displayed as mean (± SEM) percent time the pup spent socially engaged with the mother, as calculated from total time pups spent crawling to the mother, probing the mother, sleeping/laying on the mother, and nipple attached to the mother (n = 5/group).
