| Research Abstract |
Biological mechanisms of the livings on the earth always suffered the grvity effect and usually adapted to the 1-G environments in a normal condition. Including human beings, all of the living spieces seems to have the central-peripheral adaptation programming mechanisms individually and genetically. When one of the spieces go to the different G condition, such as in a space, O gravity gives them a lot of loards to be accustummed to the another gravity conditions. It takes a time. If they wants to live longer in that condition they have to change their behavioral and neurophysiological mechanisms and function. If they reache to some adaptation level, the question comes how do they get the plasticity for their native function, or how do they adapated their individual functions apart from genetic history. These question leads the fundamental research aitems to be studied how the human beings get gravity infomation individally and genetically. The research done here was categorized into f

our reseach items, such as 1) how changeable the innate behavior of the human beings after rather longer abnormal gravity condition, 2) how the plasticity become overt under the visual transformed condition experimentally, 3) how the short term micro-gravity gives the adaptation to the human beings, and 4) analyze the behavioral data under the prolonged prism adaptation for the human vision is carefully done. The experiments done in the project were simply categorized into two conditions, one is long term ground base experiment and the other one is short term O-gravity experimental condition. The rusults from the ground base experiments showed us that the plasticity to the new full adaptation behavior needs rather longer term, however a part of behavioral change emerged very quickly. Short term space experiment showed that the rather fully adapted behavior to the O-gravity is not fully supported between the cooperation of the anti-gravity muscle and non-anti-gravity muscle. The results leads us that more extensive research for the motor-motorcoordination under the various gravity condition will be needed. Less
