Shown are the mean and (SEM) percent of c-fos+ cells in the BLA, central amygdala (CeA), bed nucleus of the stria terminalis (BNST), and dorsal raphe nucleus (DRN) after yohimbine reinstatement for each group of mice.
↵aSignificantly different from saline-only group.
↵bSignificantly different from yohimbine/saline group.
