The translational vestibuloocular reflex (TVOR) produces an eye movement response to linear head acceleration detected by the otolith organs in the inner ear. This study examines the linearity of the TVOR by comparing the response to a transient sum-of-sinusoids stimulus with the responses to each sinusoid component of the sum. A head-fixed rhesus monkey was translated in the dark along its interaural and nasooccipital axes with sinusoidal and transient motion. Eye movements were recorded using the magnetic search coil technique (Robinson 1963). The results of this study show that the TVOR displays linear characteristics during interaural translation for 0.5--7 Hz stimuli. The eye response to sinusoidal stimuli is consistent across the stimulus frequency range. However, the eye response to transient stimuli starts to exhibit a frequency-dependent trend at the higher frequencies thus suggesting that nonlinearities in the TVOR may exist for frequencies above the range used in these experiments.
