Abstract: Long-term exposure to microgravity causes sensorimotor adaptations that result in functional deficits upon returning to a gravitational environment. At landing, the vestibular system and the central nervous system, responsible for coordinating head and eye movements via the vestibulo-occular reflex (VOR), are adapted to microgravity and must re-adapt to the Earth’s gravitational environment. This re-adaptation causes decrements in gaze control and dynamic visual acuity, with astronauts report…
