Figure 4. Time spent in each side by Slc6a4 mice during the tests for (a) sociability and (b) preference for social novelty.
Neither male nor female Slc6a4-null mice, or female heterozygous mice, had a significant preference for proximity to stranger 1. Data shown are mean + SEM for each group. * p<0.05, within-group comparison, stranger 1 side different from empty cage side (a) or stranger 2 side (b). # p<0.05, comparison with same measure in both +/+ and +/− male mice.
