摘要
人们虽然在应用相关维数分析脑电信号的研究方面做了许多工作，但还未将此方法应用于临床脑电分析，作者通过对脑电信号和其替代信号的功率谱和混沌特性的研究表明，相关维数包含了功率谱未包含的信息。将此方法与目前临床检测中功率谱分析法相结合，将对大脑疾病诊断和脑疾定位诊断提供更多有用的信息。相关维数法可能成为临床脑电分析的新方法。
Although people have done a lot of research works on using correlation dimension to ana-lyse EEG signals,the method hasn't really been used in clinics In this paper ,we comparecorrelation dimension and power spectrum of a EEG segment and its surrogate data Results show that correlation dimension provides information ,which is not contained in power spec- trum. Combined with current clinical spectrum analysis method, this one will be helpful in clin- ics in respect of diagnosing brain diseases and determining position of brain diseases Proba-bly,correlation dimension method will be a new method to analyse EEG in clinics.
