| 摘 要： | 基于脑电（EEG）信号与Kolmogorov 熵（KE），对复杂数学运算状态下的大脑一侧优势进行了分析及定位。在复杂数学运算状态下，顶区左、右侧KE值的大小存在显著性差异，而中央区与枕区左右侧KE值的大小则不存在显著性差异。分析结果表明，在复杂运算状态下，不论是左利手还是右利手，大脑顶区都呈现显著的左侧优势，但大脑顶区的左侧优势并不是绝对的；基于EEG与KE的动态比较的方法来分析大脑一侧优势是可行的。

| Abstract: | Based on electroenphalogram(EEG) and Kolmogorov entropy(KE),cortical lateralization is analyzed and localized during mental task of complex problem solving.There are significant differences between the KE values of left and right parietal regions during complex problem solving,while no significant differences on KE values in the central zone and the occipital region.The results indicate that,during complex problem solving,there are significant left cortical lateralization in the parietal region both for right-handed and left-handed.This cortical lateralization is not unchangeable.The method based on EEG and KE is practical for analysis and localization of cortical lateralization. |
