Sex-dependent differences in bout duration during the SP test
(A) Cumulative mean ΔIT (±SEM), plotted against bout duration during the SP test, separately for males (blue) and females (brown) of the three strains. Inset – same data on a larger scale for bout duration<10 s.
(B) Mean ΔIT (±SEM), calculated separately for short (≤6 s) investigation bouts made during the SP test by each animal group.
(C) As in (B), for long (>6 s) bouts. ∗p< 0.05, ∗∗p< 0.01, ∗∗∗p< 0.001, ns – not significant, post hoc t test in cases of no multiple comparisons (C) and post hoc Holm-Sidak test, following main effect in two-way ANOVA test.
