The mean ± SEM number of Fos-IR neurons in the granule cell layer of the AOB are compared in subjects treated with EB or TP and exposed to clean bedding, soiled male bedding, or soiled female bedding. The number of subjects in each group is given in parentheses. Asterisks denote a significant (p<0.05) effect of soiled versus clean bedding (Kruskal–Wallis ANOVA with post hocMann–Whitney U tests). Daggers indicate significant differences between rostral and caudal means for a particular group, as determined by two-way ANOVAs, followed by Student– Newman–Keulspost hoc tests.
