对思维时的脑电信号混沌态进行了研究。在研究中首次引入了阵发性４０Ｈｚ脑电图检测技术借以确定用于混沌态分析的数据段，以确保分析结果的可靠性和稳定性。文中对混沌定量计算的参数也进行了一定的研究，对３０多位受试者的脑电信号样本进行了分数维值和最大李亚谱诺夫指数计算。实验结果表明分数维值对临床应用确有价值，而仅凭一个最大的李亚谱诺夫指数似乎不能有助于诊断疾病。
The chaotic state of EEG signals in thinking is studied. The first time in the study the introduction of paroxysmal 40Hz EEG detection technology to determine the data used for chaotic state analysis of the data segment to ensure the reliability and stability of the analysis results. The parameters of chaos quantitative calculation are also studied in this paper. The scores of EEG signals and the largest Lyapunov index of more than 30 subjects are calculated. Experimental results show that the value of the fractal dimension is of great value to clinical application, and the mere appearance of one of the largest Lyapunov indices does not seem to be conducive to the diagnosis of the disease.
