Average percentage PPI in the four treatment groups: WT/veh, WT/CP, HET/veh, and HET/CP in both sexes. All groups were administered saline (Sal; open bars) and 0.4 mg/kg CP55,940 (CP; black bars) before the PPI test. HET mice had significantly lower PPI after saline injection compared to wild-type controls. Acute CP treatment increased PPI in male “two hit” mice and in all female groups. *P < 0.05 for difference with acute saline based on genotype × acute treatment interaction and post-hoc comparisons (males) or main ANOVA effect (females). **P < 0.05 for difference between HET mice and wild-type controls based on ANOVA main effect.
