Plasticity and behavioral change under the prolonged unusual gravity environment

地球上生物的生物机制总是受到重力效应的影响，通常在正常情况下适应1-G环境。包括人类在内的所有生物似乎都具有个体和遗传上的中枢-外周适应编程机制。当其中一个片段进入不同的G条件时，例如在空间中，O引力给了它们很多空间来适应另一个引力条件。这需要时间如果他们想在这种情况下活得更长，他们必须改变他们的行为和神经生理机制和功能。如果它们达到了一定的适应水平，问题就来了，它们如何获得其天然功能的可塑性，或者它们如何适应除了遗传历史之外的个体功能。这些问题导致了人类如何个体地、遗传地获得重力信息的基础研究项目。这里所做的研究被归类为f 关于我们 对1）人类在较长时间的异常重力条件下的先天行为如何发生改变，2）在视觉转换条件下的可塑性如何表现出来，3）短期微重力条件下人类对环境的适应，4）长时间棱镜适应条件下人类视觉的行为数据分析等问题进行了细致的研究。该项目所做的实验简单地分为两种情况，一种是长期地基实验，另一种是短期O-重力实验条件。基础实验的结果表明，新的完全适应行为的可塑性需要较长的时间，但部分行为变化很快出现。短期空间实验表明，在反重力肌和非反重力肌的协同作用下，并不能完全支持对O-重力的适应行为。研究结果表明，在不同的重力条件下，需要对运动-运动协调进行更广泛的研究。少

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 … More 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
