Translational vestibulo-ocular reflex (tVOR) elicited during translations along axes in the sagittal plane. A: axes of the right and left eyes, which have larger magnitudes for translations toward the front of the animals (black, pink, red, and orange) than toward the back of the animal (green, light blue, dark blue). B: normalized data are shown to visualize the spatial spread of the sagittal plane tVOR; each animal’s data are represented with the markers described in the legend. C: axis of eye velocity recorded from 6 chinchillas during 1-Hz sinusoidal translations along 8 axes in the sagittal plane with peak 2 m/s2 acceleration is shown. D: a boxplot of the ratio of right eye/left eye velocity illustrates that the 2 eyes rotate at approximately the same velocity for translations in all the directions. F: the boxplot shows component-wise eye velocity for each axis of translation, illustrating that the 2 eye remain primarily disconjugate in roll and yaw, and conjugate in pitch. All outliers larger than 3 times the interquartile range for D and E were removed (fewer than 6 of 131 samples were removed for each plot). Each box plot for each axis has samples n ≥ 13.
