M.I.T./Canadian vestibular experiments on the Spacelab-1 mission. I - Sensory adaptation to weightlessness and readaptation to one-g: An overviewHuman sensory/motor adaptation to weightlessness and readaptation to earth's gravity are assessed. Preflight and postflight vestibular and visual responses for the crew on the Spacelab-1 mission are studied; the effect of the abnormal pattern of otolith afferent signals caused by weightlessness on the pitch and roll perception and postural adjustments of the subjects are examined. It is observed that body position and postural reactions change due to weightlessness in order to utilize the varied sensory inputs in a manner suited to microgravity conditions. The aspects of reinterpretation include: (1) tilt acceleration reinterpretation, (2) reduced postural response to z-axis linear acceleration, and (3) increased attention to visual cues.
