P values from multiway ANOVA of the VOR gain and phase during sinusoidal rotations. Conjugacy compares gains and phases for left and right eyes. Direction compares gains and phases for positive and negative stimulus half-cycles. Orientation compares gains and phases for nose-up and nose-down starting orientations of the animal. Stimulus frequency is divided into 3 ranges: low (0.02–0.1 Hz), medium (0.2–1 Hz) and high (2–10 Hz). Velocity data, i.e., 20, 50 and 100°/s peak sinusoids, are pooled. Gains were disconjugate during LARP and RALP rotations because the eye rotating torsionally in eye coordinates had a smaller gain than the eye rotating vertically in eye coordinates. Orientation affected the gain and phase probably because during nose-down orientations (LARP–REDND and RALP-LEDND) the quality of eye movement data was low due to lacrimation and a tendency of eyelids to partly close. Bold P values denote a statistically significant difference. LARP=left-anterior/right-posterior; RALP=right-anterior/left-posterior; LED/RED = left/right ear down; ND = nose down.
