a Photostimulation of either the ChR2 (blue) or the eArchT (green) in the CAMK2-expressing neurons located in the vestibular nucleus complex (VNC) induced body tilt. Excitatory photostimulation induced body tilt to the contralateral side while inhibitory photostimulation showed the opposite response. Please see the Video S1. b, c Summarized data of the changes in body tilt angle induced by excitatory (b) or inhibitory (c) photostimulation. Statistics: unpaired t test; t(14) = 6.726, P < 0.0001 (b) and t(14) = 3.446, P = 0.0039 (c). d, e Summarized data of the body tilt angle induced by changes in the frequency of excitatory (d) or inhibitory (e) photostimulation. A two-way ANOVA with Tukey’s multiple comparisons test was applied; F(4, 56) = 27.11, P < 0.0001 (d) and F(4, 56) = 29.96, P < 0.0001 (e). For all statistical analyses, single, double, or triple significance symbols indicate P < 0.05, P < 0.01, or P < 0.001, respectively (color figure online)
