Table 2. The effect of gaze on OVEMP and VOR magnitude.
The average OVEMP amplitudes and VOR magnitudes ± SEM for Upgaze (U) Straight ahead (S) and downgaze (D) for both eyes Those from the eye contralateral to the stimulus are shaded. The OVEMP amplitudes fell from upgaze to straight ahead and down, but the VOR was unaffected.
