Electroencephalogram (EEG) basic rhythms in different brain states possess different features, so it is important for quantitative EEG analysis to extract them efficiently.

脑电中不同类型的基本节律在不同生理条件下特征不同，有效提取这些特征对于实现脑电定量分析具有重要作用。

ConclusionBeing a quantitative method of non-Gaussianilty and nonlinearity for EEG study, the bispectral analysis can give more useful high-order information.

结论作为脑电信号非线性定量分析的一种研究方法，双谱分析可显示出常规脑电分析时无法显示的有价值的高阶信息。

Conclusion: Quantitative pharmaco EEG could be used to reflect dynamic changes of brain function.

结论：定量药物脑电图能反映人脑的功能变化。
