Figure 1

Levels of (A) progesterone, (B) 5α-dihydroprogesterone (DHP) and (C) allopregnanolone (AP) in the prefrontal cortex of D1CT-7 and wild-type (WT) littermates following spatial confinement (SC). All measurements were performed after 20 min of SC. Data are shown as means ± SEM. *P < 0.05, and ***P < 0.001 for comparisons indicated by dashed lines. Main effects for genotype are indicated as comparisons between brackets. Main effects for SC are indicated as comparison between symbols. N = 4–7/group. NC, no spatial confinement.
