高重力加速度及其模拟条件下脑电变化研究综述

Survey of electroencephalograph change under real and simulated high gravity acceleration

高重力加速度及其模拟条件下脑电变化的相关研究在航空医学领域具有重要意义。本文综合介绍了飞行中+Gz和离心机+Gz作用、下体负压作用、不同程度缺氧、短暂意识丧失下的脑电变化特点及其相互之间的关系。国内外学者围绕+Gz及其模拟条件下的脑电变化规律已取得一定研究成果,但在脑电的定量分析,以及利用脑电对+Cz加速度引起的短暂意识丧失进行前驱预警等方面的研究尚待深入。本文为高重力加速度环境下的脑电变化特征研究提供重要参考依据,对探寻利用脑电预警高重力加速度引起的意识丧失具有现实意义。

The correlation study on electroencephalograph （EEG） change under high gravity acceleration and the action of different methods which simulate biological effects induced by high gravity acceleration has an important significance in aviation medicine field. This paper comprehensively introduces EEG change characteristics under centrifuge ＋ Gz acceleration, lower body negative pressure, hypoxia of different degrees, temporary loss of consciousness, and the associations among them. Domestic and foreign scholars have obtained certain achievements in the EEG change rules, yet the research depth is not enough in the quantitative analysis of EEG and the EEG precursor warning for the transient loss of consciousness caused by ＋ Gz acceleration. This paper provides important reference for the characteristic study of EEG change under high gravity acceleration environment, and has practical significance in the EEG warns for the loss of consciousness caused by high gravity acceleration.
