Performing a rapid eye movement to a desired goal, the oculomotor system solves several computational problems: First, it visually represents the spatial location of the goal target. Second, it transforms this representation into a motor command to activate the eye muscles. Third, it predicts the visual consequences of the motor command via simulation of the eye dynamics by an internal forward model. Moreover, due to fluctuations like motor error or muscle fatigue, the transformation process needs to be continuously calibrated to maintain appropriate landing accuracy. This process of oculomotor adaptation can be induced experimentally by shifting the target while the eyes are in flight.
Initially, oculomotor adaptation was believed to rely on the late motor circuitry of the cerebellum and the brain stem. However, recent findings show that it also involves changes in visuospatial representations. My research work aims to examine the plasticity of oculomotor learning in visuospatial, motor and forward model coordinates via computational and behavioral methods.
