Baseline dynamic properties of VOR and OKR in γ2pepV mice. VOR in the dark (A, B), VOR in the light (C, D), and OKR (E, F) in γ2pepV (n = 5) and control (n = 5) mice. Gain (A, C, E) and phase (B, D, F) values of the eye movement relative to head or screen rotation are plotted versus the stimulus frequency. Data are mean ± SEM.
