不同生理状态时脑电时间序列的三神复杂度计算比较

THE COMPARISON AMONG COMPLEXITIES OF EEG TIME SERIES IN DIFFERENT PHYSIOLOGICAL USING THREE KINDS OF ALGORITHMS

为了研究不同生理状态下的脑电复杂度变化特点，本文依照１９９４年徐京华等人应用的算法，对４种状态（安静睁眼、清醒闭目、浅度睡眠、深度睡眠）下的三种脑电复杂度（ＫＣ、Ｃ１、２）的变化规律进行了比较分析，ＫＣ与Ｃ１的变化相一致。从安静睁眼到清醒闭目到浅睡到深度睡眠，ＫＣ与Ｃ１值均依次下降。Ｃ２值的变化则与它们相反，尤其在深睡期显著升高。实验结果提示，复杂度可做为脑电时间序列的研究指标。

In order to observe the variation characteristics of EEG complexity in different physiological states, 3 kinds of EEG complexities (Kc, C1, C2) in 4 kinds of states (rest with eyes opend, resting conscious with eyes closed, slight sleep and deep sleep) were analyzed using the algorithms applied by Xu Jinghua et al, 1994. Kc and C1 varied coincidently. Kc and C1decreased by turns from rest with eyes opened, resting conscious with eyes closed, slight sleep and then to deep sleep. On the conakry, C2 varied oppositely. Especially during deep sleep state, C2 increased significantly. Results suggest that the complexity could be regarded as a parameter in the study of EEG the series.
