Abstract
In order to provide adequate multivariate measures of information flow between neural structures, modified expressions of partial directed coherence (PDC) and directed transfer function (DTF), two popular multivariate connectivity measures employed in neuroscience, are introduced and their formal relationship to mutual information rates are proved.
摘要
为了提供神经结构之间信息流的充分多变量测量方法，引入了神经科学中常用的两种多变量连通性测量方法——部分定向相干性（PDC）和定向传递函数（DTF）的修正表达式，并证明了它们与互信息率的形式关系。
