Gaze relative to head (G-H) was the best predictor of learned change of VOR gain. A, Joint histogram showing the correlation between G-H and the learned change of VOR gain across individual training sessions. B, Mutual information about the learned gain change carried by the phase of gaze relative to head (G-H) and other candidate instructive signals. Mutual information was calculated in bin sizes of 1, 2, 5, 10, or 20° for G-H, E-H, R-H, and R-G and bin sizes of 0.1, 0.2, 0.5, 1, or 2 °/s for Rs, Es, or Gs.
