连通性测量是(通常是双变量的)统计测量,可用于从电生理数据估计大脑区域之间的相互作用。我们回顾了一系列这样的方法的正式和非正式描述,这些方法适用于分析人脑的电生理数据,主要是脑电和脑磁图。方法在空间-时间、空间-频率和空间-时间-频率域中描述。综合考虑了信号处理和信息论方法,区分了线性方法和非线性方法。介绍了一组新的交叉时频测量方法,其中包括一种交叉时频相位同步测量方法。
Connectivity measures are (typically bivariate) statistical measures that may be used to estimate interactions between brain regions from electrophysiological data. We review both formal and informal descriptions of a range of such measures, suitable for the analysis of human brain electrophysiological data, principally electro- and magnetoencephalography. Methods are described in the space-time, space-frequency, and space-time-frequency domains. Signal processing and information theoretic measures are considered, and linear and nonlinear methods are distinguished. A novel set of cross-time-frequency measures is introduced, including a cross-time-frequency phase synchronization measure.
