cFos activation in hippocampus. a Schematic representation of the hippocampal structures selected for cFos density analysis. b cFos density in “Home Cage,” “Context Only,” “Recall,” and “Extinction” groups in the dDG (ANOVA, F(3, 25) = 3.9, P = 0.02, n = 6–8) and dCA3 (ANOVA, F(3, 25) = 0.7, P = 0.5, n = 6–8), dCA1 (ANOVA, F(3, 25) = 1.2, P = 0.3, n = 6–8), vDG (ANOVA, F(3, 25) = 4.1, P = 0.02, n = 6–8), vCA3 (ANOVA, F(3, 25) = 9.6, P = 0.0002, n = 6–8) vCA1 (ANOVA, F(3, 25) = 5.2, P = 0.006, n = 6–8). *P < 0.05; **P < 0.01; ***P < 0.001, by Sidak post-hoc tests. c Representative pictures of cFos immunohistochemistry in the vCA1.
