Figure 3From: Induction and requirement of gene expression in the anterior cingulate cortex and medial prefrontal cortex for the consolidation of inhibitory avoidance memoryArc expression in distinct brain regions after IA training. (A) Representative immunohistochemical staining of PL, IL, BLA, CA1, and ACC Arc-positive cells from the indicated mice. Scale bar, 50 μ m. (B) Arc expression in the LA, BLA, and CeA regions of the amygdala (home cage, n = 11; US only, n = 10; CS only, n = 12; CS-US, n = 10). (C) Arc expression in the CA1, CA3, and DG regions of the hippocampus (home cage, n = 11; US only, n = 11; CS only, n = 13; CS-US, n = 11). (D) Arc expression in the prelimbic and infralimbic regions of the mPFC (home cage, n = 13; US only, n = 12; CS only, n = 14; CS-US, n = 12). (E) Arc expression in the cortex regions (ACC: home cage, n = 13; US only, n = 12; CS only, n = 14; CS-US, n = 12; VC, TC, PRh, and EC: home cage, n = 10; US only, n = 9; CS only, n = 12; CS-US, n = 11). Error bars are SEM. *P < 0.05, compared with the other groups. Arc expression for each group is expressed as the ratio of the home cage group to the other groups.Back to article page
