VOR Adaptation in Virtual Reality: Implications for Stationarity Perception. MacNeilage, P., Rodriguez, V., & Allison, R. S. In Abstracts Vestibular-Oriented Research Meeting.

-1 doi abstract bibtex Virtual reality is well-suited for studying oculomotor adaptation in general, and adaptation of the vestibulo-ocular reflex (VOR) in particular, due to the availability of both head and eye tracking as well as a high degree of control over presentation of visual stimuli. However, a search of the literature suggests that few if any previous studies have used virtual reality to study adaptation of the VOR. In the current study, we use virtual reality to adapt the horizontal VOR from a gain of 1 to a gain of 0.6 over a span of 150 trials. Immediately after adaptation, we measure stationarity perception, that is the accuracy and precision of observers' judgments about gain of visual scene motion during head turns that leads to perception of a stationary (i.e. world-fixed) visual environment. Interleaved with these perceptual trials are VOR catch trials in the dark that allow observing the persistence of VOR adaptation. Results suggest that adaptation persists in most subjects, but with some subjects showing VOR gain drifting back toward the unadapted state. We also observe a decrease in the visual gain perceived as stationary relative to baseline measures, suggesting that the neural circuits that mediate the VOR also play a role in stationarity perception. This study serves as a proof of concept for using virtual reality to study oculomotor adaptation and also demonstrates the dependence of stationarity perception on the state of oculomotor adaptation.
