Mutual information tools have been recently applied to quantify the connectivity between brain regions in functional magnetic resonance imaging (fMRI). Here we develop measures of mutual information between clusters of brain regions in the frequency domain. The properties and limitations of the method are exemplified through a single resting state fMRI dataset, and with a comparison involving frontostriatal connections in schizophrenic patients and healthy controls.
互信息工具最近已被应用于量化功能磁共振成像（fMRI）中脑区之间的连通性。在此，我们开发了频域中脑区簇之间的互信息测量方法。该方法的特性和局限性通过一个单一的静息态fMRI数据集进行了举例说明，并与涉及精神分裂症患者和健康对照者额纹状体连接的研究进行了比较。
