Abstract

The ground-based studies with isolation (105- and 520-d isolation campaigns within the MARS-500 project) and modeled microgravity (5- and 21-d dry immersion) were aimed to test an integrated method of rapid assessment of the brain energy and electrical activities indicative of a current CNS status and adaptive changes. The method consists of synchronous recording electroencephalogram (EEG), constant potential level (CPL), and a number of psychophysiological tests. Analyzed parameters are a EEG pattern, relative power of EEG θ- (4–8 Hz), α- (8–13 Hz) and β-1- (13–25 Hz) waves, averaged CPL, ΔCPL values, and interhemispheric asymmetry. The method that measures CNS tension in response to psychological and physical stresses, adaptation to an unusual environment, fatigue and readaptation can be used to examine cosmonaut's CNS functioning prior to and after space mission, and in the period of post-mission recovery.

宇航员对中枢神经系统功能评估综合方法的可能性

基于地面的隔离研究(MARS-500项目中105天和520天的隔离运动)和模拟微重力(5天和21天的干浸泡)旨在测试一种快速评估表明当前中枢神经系统状态和适应性变化的脑能和电活动的综合方法。该方法由同步记录脑电图(EEG)、恒电位水平(CPL)和一系列心理生理测试组成。分析的参数包括脑电模式、脑电θ- (4-8 Hz)、α- (8-13 Hz)和β-1- (13-25 Hz)波的相对功率、平均CPL、ΔCPL值和半球间不对称性。测量中枢神经系统对心理和生理压力的反应、对异常环境的适应、疲劳和重新适应的方法可用于检查宇航员在太空任务前后和任务后恢复期间的中枢神经系统功能。
