Corticosterone (CORT) blocker injection (metyrapone) prevents social transmission of scarcity-adversity effects to pup engagement with a mother in a social behavior test. (a) Depiction of model of disruption of social transmission via CORT blockade (metyrapone). (b) Depiction of experimental procedure. (c) Pup engagement with mother in a social behavior test as a function of early-life rearing condition (control vs. scarcity-adversity) and pharmacological manipulation (saline vs. metyrapone injection). 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 (** indicates p < .01; n = 8/group).
