Concentrations of progesterone (ng/g) in the medial prefrontal cortex (top panel) and hippocampus (middle panel) positively correlated with the percentage of time that rats spent in the novel arm of the Y-maze and accounted for a significant proportion of variance in this behavior. Progesterone metabolism to its 5α-reduced metabolites (DHP+3α,5α-THP:P ratio) in the hippocampus (bottom panel) negatively correlated with the percentage of time that rats spent in the novel arm of the Y-maze and accounted for a significant proportion of variance in this behavior.
