Bar plot for mean PSE values (error vertical line representing 95%CI) in C Down (left) and C Up (right), same icons and color code as Fig. 3. RM-ANOVA for PSEs highlighted a significant effect of C direction and of the interaction between session and C direction. Planned pairwise comparisons highlighted that the latter effect is due to higher PSEs in VI-Down and VE-Down than in VI-Up and VE-Up, respectively, and to higher PSEs in VE-Down than in VV-Down. VV blocks are depicted according to the C direction of their vestibular stimulation. (**, p < 0.010. ***, p < 0.001).
