Figure 3.
The effect of different horizontal gaze angles on average measured vertical VOR gain for LARP impulses for 10 subjects. Means for individual subjects are shown by the light traces; the heavy trace shows the mean across subjects, with error bars for the two-tailed 95% confidence intervals of the mean. A gaze angle of 40° corresponds to the standard LARP testing protocol, with the gaze direction aligned with the LARP canal plane; 0° corresponds to gaze straight ahead. For both leftward impulses (A) and rightward impulses (B) a clear decline of gain with increasing gaze angle is apparent (C).
