Eye, Head and Arm Coordination and Spinal Reflexes in Weightlessness — MONIMIR Experiment

One of the most important fields of research being conducted in space medicine concerns the effect of weightlessness on the human locomotor system and its control systems in the central nervous system. Under terrestrial conditions, the earth’s gravitational field constantly influences all sensory motor functions. Only by adapting to gravity is it possible for man to assume an erect posture. Studies of human motor functions under microgravity offer new possibilities for analyzing the sensory motor systems and their influence on posture and motion.
