Effect of accessory olfactory bulb lesions on the time spent by male mice investigating urinary volatiles from gonadally intact male vs. estrous female mice in home-cage habituation/dishabituation tests. The sequence of urinary odor stimuli was reversed in the two tests (Panels A and B) given on consecutive days. Wilcoxon Signed Rank Tests were used to make within groups comparisons of the time spent investigating the third presentation of one odor and the first presentation of the next odor: &, #, $ indicate a significant difference ( p<0.05) in investigation times for males in the sham-operated, complete AOB lesion, and partial AOB lesion groups, respectively. Δ indicates a significant overall group difference in investigation times by a Kruskal Wallis One-Way ANOVA on ranks. Data are expressed as mean±SEM; group numbers are given in parenthesis.
