Acceleration gain (G_A; left) and constant-velocity gain (G_V; right) after sinusoidal visual-vestibular mismatch adaptation training. cba129 mice (top) demonstrated pronounced changes in G_A after adaptation training with a significant effect of adaptation, measured as the difference between gain-increase and gain-decrease conditions. This difference was mostly due to gain-decrease adaptation resulting in significantly lower than baseline gains at all stimulus conditions. In contrast, α9-knockout mice (bottom) showed adaptation of G_A only at 6k acceleration but none for G_V at any stimulus condition. Significant difference: *P < 0.05, **P < 0.01, ***P < 0.001.
