NGFI-B mRNA expression in the hippocampus is upregulated during context-shock memory consolidation but not reconsolidation. A, qPCR showed that NGFI-B mRNA expression was upregulated in the hippocampus 1 h after contextual fear conditioning but not 1 h after context-shock memory reactivation. B, NGFI-B mRNA expression in the hippocampus in the T+1 group differed significantly from expression in the Box and LI groups; the expression in both control groups did not differ significantly from that in the naive group (naïve and T+1 are the same as in A). Data are means ± SEM; *p < 0.05; **p < 0.01. C, NGFI-B mRNA expression in the hippocampus did not significantly differ between the naive and Tone groups. Thus, the upregulation after contextual fear conditioning was specific for the learned association.
