| 摘 要： | 目的探讨图形记忆任务过程中脑电非线性动力学特性的变化规律，以及脑电非线性分析在记忆过程研究中的作用。方法用关联维数（D2）对30名健康老年人在安静睁眼、图形记忆任务过程中的脑电数据进行分析。结果相对于安静状态，记忆过程D2值升高（P〈0．05）；不同记忆过程大脑功能活动的复杂度和参与的脑区不同。脑电非线性分析可以清晰展示记忆过程中激活脑区的分布情况，以及与记忆相关的脑区活跃程度的变化。结论脑电非线性动力学分析方法适合于研究记忆过程中脑功能活动的变化规律和大脑的工作机制。

| Abstract: | ObjectiveTo investigate the changes of non-linear dynamics characteristics of EEG during picture memory masks, and the application of non-linear dynamic analysis for memory research.MethodsEEGs of 30 healthy old volunteers were recorded under the states of opened eyes and picture memory. Correlation dimension (D_2) was calculated for all subjects.ResultsD_2 increased significantly during memory tasks compared with the rest state with eyes opened ( P<0.05). In different memory tasks, the complexity of mental functions and the regions involved in the memory task were different.ConclusionNon-linear analysis is appropriate for the study of functional changes and working mechanism of brain during memory. |
