自发脑电检查已应用60余年,其结果通常用肉眼分析,此即常规脑电图。近十来年,由于电子计算机用于自发脑电信号分析,使得脑电定量分析技术发展很快,成了常规脑电图的重要补充,并使其精细化。脑电定量分析,其表达方式有功率百分比数据表、功率谱数据表、功率谱曲线图、功率谱直方图、压缩谱阵图、各频段功率分布地形 Spontaneous EEG examination has been used for more than 60 years, the results are usually analyzed with the naked eye, which is conventional electroencephalogram. In recent ten years, due to the electronic computer for spontaneous EEG signal analysis, EEG quantitative analysis technology has developed rapidly, has become an important supplement to conventional electroencephalography, and make it fine. EEG quantitative analysis, the expression of the power percentage data sheet, power spectrum data sheet, power spectrum curve, power spectrum histogram, compressed spectral map, the frequency band power distribution topography
