A–D: torsional aVOR gains obtained before (○) and after (●) decrease in supine (nose up) position in animal M0102. E–H: gain changes expressed in percent and plotted as a function of the head orientation in four tested planes. Gain changes were fitted with a cosine function (see text for details). Changes in bias were significant in every instance (E–H), indicating changes in the gravity-independent component. Changes in the gravity-dependent component were not significant. Insets: head orientation to the axis of tilt utilized for 4 planes of head tilt.
