RIA measurement from pups immediately following odor-shock conditioning indicates that CORT levels increased only in Infant Naïve/PN12 Paired pups receiving odor-shock conditioning for the first time during the postsensitive period (PN12) (n = 5–7/group). All other groups, including the Infant Odor Only/PN12 Odor Only group that did not receive shocks, show levels of CORT similar to PN8 Paired pups (still in the Stress Hyporesponsive Period; SHRP). Asterisk represents a significant difference from each of the other groups (p < 0.05).
