  • Oculomotor-Vestibular Physiology

    Dr. Lewis Chen studies the neural mechanisms of sensory-motor integration. His focus of research is eye-head coordination and perceptual control of movements and postures. His laboratory uses psychophysics, single neuron recording, neural deactivation, microstimulation and simulation techniques to address the above questions. His is currently using extra-oculomotor muscles as a model to investigate the neural control dysfunctions in strabismus and vestibular pathology.
