Figure 2

Area- and size-dependent analyses of PV-positive neurons. A significant difference was not found between the EE and SE rats in PV-positive large cells (Aa, b). However, the number of PV-positive small cells significantly increased in EE rats both in LA (repeated measures two-way ANOVA, significant main effect of group, F (1, 13) = 16.94, p < 0.005, Ba) and BLA (repeated measures two-way ANOVA, significant main effect of group, F (1, 13) = 10.26, p < 0.01, Bb). A significant interaction between group and AP level was found in PV-positive small cells only in BLA. *, * *, significant difference between SE and EE (Bonferroni tests, p < 0.05, p < 0.001, respectively) (Bb). The white bars indicate the number of PV-positive cells for SE rats, and black bars indicate those for EE rats.
