摘要
脑电是脑神经细胞电生理活动在大脑皮层或头皮表面的总体反映。本文介绍了Lorenz散点图、Lyapunov指数、相关维数、复杂度等几种非线性动力学方法以及它们在心理学脑电信号分析中的应用,并对这些方法进行了分析比较。
The electroencephalogram (EEG) is a technique for measuring the combined electrical activity of many brain cells on the cerebral cortex. In this paper, A brief survey was made of several nonlinear dynamic analysis methods, such as Lorenz plot, Lyapunov exponents, attractor dimension, and complexity. A comparison was also made among these techniques.
