Peak coordinates [Montreal Neurological Institution (MNI)] are reported for cluster components in descending volume order for at least 90% of cumulative volume. CinG, Cingulate gyrus (anterior division); FP, frontal pole; IFG, inferior frontal gyrus (pars opercularis); LOC, lateral occipital (superior division); MFG, middle frontal gyrus; PO, parietal operculum; PreCun, precuneus; PreMot, premotor; SMG, supramarginal gyrus (posterior division); V2, visual area V2 (prestriate cortex); Broca, Broca's area. N_Overlap, mean number of overlapping voxels; N_Voxels, mean number of voxels. The fslcc correlation coefficients indicate the spatial correlation between EEC-IC and BOLD-ICA components for both real and RAND. p values (using t test) for the comparison of real and randomized overlap voxel counts are reported in the right-most column.
