摘要
以不同的潜伏期和幅度非线性迭加在自发脑电上的单次诱发电位 ,是诱发电位和自发脑电的一种可能的非线性组合。对诱发电位进行非线性动态提取是近年来备受关注而又十分困难的课题。本文综述了三种非线性的诱发电位动态提取方法 :自适应径向基函数神经网络方法、小波变换的非线性阈值系数方法以及模糊聚类方法 。
That the evoked potential is superimposed on the spontaneous EEG nonlinearly through different latency and amplitude may be a possible way they couple together.Recently it has been widely discussed about the nonlinear dynamic extraction of the evoked potential.This paper introduces the outlines and typical applications of three kinds of these methods,i.e.the adaptive radial basis function neural network,wavelet transform with nonlinear threshold,and fuzzy clustering.
