General concept of frequency-specific ISC analysis. Voxel-by-voxel ISC is calculated across subjects over the original fMRI time-series as well as over several frequency sub-bands. The method is extended to a multi-subject analysis by combining the results of each subject pair into a single statistic representing an average across-subject similarity.
