Effects of Retinal Image Slip on Modulation of Visual Vestibulo-Ocular Reflex During Near Viewing
Abstract: During viewing of a near target, the gain of the visually modulated vestibul-ocular reflex (vVOR) exceeds 1.0. We investigated whether retinal image slip contributes to this gain increase by measuring responses during strobe illumination. Subjects showed greater gain values during normal versus strobe illumination of the near target, even during rotation at frequencies above 1.0 Hz, indicating that retinal image velocity information is used to optimize vVOR.
