FIG. 7.

Mean ± SD asymmetry of VOR responses to actual 50 °/s peak, 1 Hz, passive whole-body rotations in darkness. We quantified gain asymmetry for VOR response by computing the ratio between the excitatory peak versus inhibitory peak difference in gain and the average gain, α = (G _E − G _I) / (G _E + G _I). This asymmetry is significantly reduced after the training (P > 0.05, ANOVA). Left normal; middle first day; right seventh day. Asterisk, significant in Student’s t test, P < 0.05; NS nonsignificant, P > 0.05.
