FIG. 3.

(A) Comparison of the pre- and post-adaptation active VOR gain for all subjects (n = 9) (mean across subjects—thick dashed black line). SD ranged 0.02–0.08. Although there is variation between subjects, there is a consistent unilateral increase in the active VOR gain due to adaptation training. (B) Comparison of the pre- and post-adaptation passive VOR gain for all subjects (n = 9). SD ranged from 0.03 to 0.12. Albeit different to the active head impulse training context, there is a consistent unilateral increase in the passive VOR gain due to training. This increase is ∼50 % of that observed in the active VOR gain.
