Middle-aged rats whose reproductive status was maintained (n=20) had shorter latencies to cross over to the shock-associated compartment of the inhibitory avoidance chamber (indicated by mean bar ± SEM bars) than did same-aged rats that whose reproductive status was in decline (n=26; top panel). Concentrations of progesterone (ng/g) in the medial prefrontal cortex negatively correlated with shorter latencies to cross to the shock associated side and accounted for a significant proportion of variance in this behavior (bottom panel). * indicates significant difference between groups, p < 0.05.
