The method and results of the MoniMir experiment, part of the investigation program of the Austrian Soviet spaceflight in Oct. 1991, which investigated the adaptation and readaptation of eye, head, and arm movements, are presented. The movements are highly coordinated under the control of visual, vestibular, and proprioceptive systems. Disturbances on the vestibular and proprioceptive systems caused by weightlessness during spaceflight are responsible for initial movement disorders in space. Visual information is primarily responsible for adaptation of the sensory motor system. Special hardware was developed for the presentation of standardized visual signals and for registration of eye, head, and arm movements. Preprogrammed movements, tracking movements, memorization of movements, and the influence of neck reflexes on arm movements were investigated. Analysis of accuracy, velocity, reproducibility of eye, head, and arm movements, and their changes during and after spaceflight gives further information on the adaptive process of the sensory motor system.
