[What the gravity environment enables us to attain].
How human beings achieve visual stability during body movements in space was investigated. When humans are exposed to an environment with different gravity environment, the pre-programmed behavior on the ground must be changed and should be re-programmed. This is habituation or familiarization. Present experiment focuses on visual, vestibular and somatosensory perception coordination and how it changes in microgravity as compared to a 1-G environment. We examined these issues under the microgravity during the mission Spacelab Japan (SL-J) mission with the cooperation of the Japanese Payload Specialist (RS), Dr. Mohri. In this paper we describe how the first human life science experiments were conducted and showed the unusual muscle cooperation between gravity specific and non-gravity specific muscle over the mission days.
