Physiological targets of artificial gravity: the sensory-motor system
other
This chapter describes the pros and cons of artificial gravity applications in relation to human sensory-motor functioning in space.
Spaceflight creates a challenge for sensory-motor functions that depend on gravity, which include postural balance, locomotion, eye-hand coordination, and spatial orientation. The sensory systems, and in particular the vestibular system,
must adapt to weightlessness on entering orbit, and again to normal gravity upon return to Earth. During this period of adaptation, which persists beyond the actual gravity-level transition itself the sensory-motor systems are disturbed.
Although artificial gravity may prove to be beneficial for the musculo-skeletal and cardiovascular systems, it may well have negative side effects for the neurovestibular system, such as spatial disorientation, malcoordination, and nausea.
