Fig. 6. Decreasing the stress hormone corticosterone (CORT) rescues maternal regulation of infant attachment behavior and cortical oscillations.

a Blocking CORT synthesis during adversity-rearing prohibited expression of atypical behavior during a 30-min social behavior test outside of the nest. b Blocking CORT synthesis during SSP prevented expression of atypical attachment behavior during reunion with the mother. Ninety minutes before SSP, pups received the CORT synthesis inhibitor metyrapone (50 mg/kg) or saline. c In an internal replication of Exp. 1, saline-treated, adversity-reared pups failed to exhibit decreased beta and gamma oscillations upon reunion with the mother; this maternal regulation was restored if they were administered metyrapone before the test. Bars represent mean ± SEM of power collapsed into frequency bands. d CORT inhibition in maltreated pups restored control-like coupling during reunion with the mother in the rSSP. Dashed line = no change from baseline; + indicates mean significantly different from baseline (1). *p < 0.05, ANOVA. Source data are provided as a Source Data file.
