Sex- and strain-dependent difference in investigation time between the two stimuli in the SP, SNP, and SxP tests
Mean (±SEM) difference in investigation time (ΔIT) between the two stimuli, measured separately for each animal group during the SP (A), SNP (B), and SxP (C) tests. ∗p< 0.05, ∗∗p< 0.01, ∗∗∗p< 0.001, ns – not significant, post hoc t test in cases of no multiple comparisons (A) and post hoc Holm-Sidak test, following main effect in two-way ANOVA test.
