# PLV PLI WPLI DTF Granger Causality

PLV：这里举两点说明，如上图所示 两个红点 电极 通过Hilbert变换求出两个信号的实时Amplitude and Phase 将当前时刻所有点的相位差求和 ，取绝对之后除以时间点的个数得到就是PLV的值 注意： N取不同值得时候得到不同的PLV，最后你得到是一个波形图 如上图右下角。 之后将PLV normalize 化 就可以很清楚的看到PLV的分布, 一般来讲，PLV介于0到1的值，如果PLV的值很随机，这两个信号就没啥关系，否则这两个信号的相位运动是一致的或者之间的延迟是固定的。 参考链接：https://praneethnamburi.wordpress.com/2011/08/10/plv/ PLI:Phase lag index 我们有一个指标就是相位延迟指数，这个是衡量两个信号之间的不对称，就是不是同起同落，而是之间有一个时间差 PLI is much less affected by the influence of common sources (volume conduction) and active reference electrodes. PLI=|sign(P1-P2)| 按照我的理解

# Automatic Anatomy Labeling Categories

AL Single-Subject Atlas The AAL-VOIs atlas is the automatic anatomical labeling result [5] of the spatially normalized, single subject, high resolution T1 MRI data set provided by the Montreal Neurological Institute (MNI)[6]. It includes 120 structure definitions. By merging some small structures an AAL-Merged atlas
