T-817MA ameliorated the decrease in density of parvalbumin-immunoreactive neurons in the mPFC (A), hippocampus (B), basolateral amygdala (BLA) (C), and superior colliculus (SC) (D) of PDGFR-β KO mice.

<p>**, p<0.01 (main effect of genotype); #, p<0.05 (main effect of treatment); a, significant difference between Cont-DW and KO-T817 in the BLA (Bonferroni test, p<0.01); b, significant difference between Cont-DW (Bonferroni test, p<0.01) and KO-T817 (Bonferroni test, p<0.05) in the SC.
