自发脑电Alpha节律的非线性动力学特性研究

Nonlinear Dynamics Characteristics in Alpha Rhythm of Scalp Electroencephalogram

针对正常对照组和精神分裂症病人自发脑电,从三个角度获取了a lpha节律波,并对其非线性进行了检验。结果表明,无论是对照组还是病人组的a lpha节律都不具有典型的非线性特征,提示对脑电节律的研究不能盲目采用非线性动力学中的相关理论,要将传统临床研究和信号处理领域有机地结合起来,才能得出有实际意义的结论。

In regard to the controls and schizophrenia EEGs, we have got alpha rhythm from three points of view and verified the nonlinearity of the three kinds of rhythms, The results show that neither normal EEG alpha nor patients EEG alpha have the typical nonlinear characteristics. Therefore, we could not blindly use the theories of nonlinear dynamics to analyze the rhythm of brain wave.
