| 摘 要： | 随着国内外对脑电非线性研究的发展,人们已经发现了脑电的混沌特性。我们在国外大量生物学实验研究的基础上,根据大脑皮层的生理和解剖性质,采用反馈这样一种系统结构,建立起大脑皮质层简化的生理模型。通过适当选择模型的参数,模拟了脑电的混沌行为,我们还连续调整了模型参数,证明了脑电的混沌是一种Rellc-Takens-NewhOuse混沌。另外,通过改变模型的参数,我们初步解释了病理条件下的脑电波形的神经机理。

| Abstract: | With the development of nonlinear study of EEG, researchers already found chaotic characteristic of EEG. Based on experimental biological study and physiological and anatomical characteristic of EEG,we established a simplified cortical model. Chaos of EEG is simulated with a feedback systematic structure. By adjusting parameters of the model,it is proved that the chaos is a Relle-Takens-Newhouse chaos. We also tried to explain the neural mechanism of pathological EEG wave by changing parameters of the model. |
