The vestibular system enables a variety of functions ranging from gaze stabilization and postural control to orientation and navigation. Because of its partial dependency on Earth's gravity, this system is challenged in a microgravity environment experienced during spaceflight. With this project, we trigger the peripheral vestibular organ of cosmonauts by centrifugation and measure ocular responses which serve as a window into the vestibular organ's function. These tests are performed before cosmonauts go to space, three days after return from their mission and at least one extra follow-up time point up to 9 days after the mission.
