    Among the 6th Chinese explorers of Great Wall Station in Antarctica,17subjects were completely administered memory performance and EEG examination beforetheir shipping,at the end of one month and two months saty in Antarctica respectively.The re-sults by the end of two months to compare with that before shipping showed no obviouschanges in scores of single memory performance,but significant prolongation of decode-timewas found in complex memory performance(P<0.001).EEG showed α wave index increasedsignificantly(P<0.05),β wave index obviously decreased whereas no regular change wasfound in θ wave.EEG findings indicate the synchronia proceeding was relatively increasedand brain excitment was relatively decreased,consistenting with the change of complex memo-ry performance in nature.Findings implicate that the Antartic environment may contribute tothe change of human brain functions.

    著者对中国第六次南极长城站考察队员17人在赴南极前,到南极后一个月末,两个月末分别进行了记忆力及基础脑电图测定。结果显示:两个月末时较之赴南极前其简单记忆测定分值无明显变化,复杂记忆译码时间明显延长(P<0.001),EEG 的α波指数明显增大(P<0.05),β波指数减少,但θ波未见规律性变化,表明生物电活动同步化过程相对增强,大脑兴奋性相对降低。此结果提示南极特殊环境对人类大脑功能有影响。著者据此就改善南极工作环境提出了建议。

    Grassberger Procaccia algorithm is used to calculate the correlation dimension of 8-channel human EEG signals. T'he influences of length of time series, time delay and embedding dimesion on the value of EEG correlation dimension were investigated. It indicated that the results of calculation are greatly influenced by the reasonable choice of parameters. Besides, it seemed that EEG signals can not be defined as a stable chaotic attractor. Therefore,the attempt to take the correlation dimension as a precise and objective parameter to indicate human brain functions in different physiological states is almost unfeasible.

    应用Grassberger—Procaciaalgorithm算法,通过点列长度、时间延迟、嵌入维数等参数的变化,对人的8导脑电时间序列的相关维数值的影响进行了研究。结果表明不仅参数的选用是否合理对计算值影响很大,而且脑电信号不像是一个稳定的混沌吸引子,因此拟用相关维数作为一项客观指标来准确地表示大脑的不同功能状态,几乎是不可能的。
