Abbreviations: CC, preprocessing with AROMA + CC; FWE‐corr., family‐wise error corrected; GSR, preprocessing with AROMA + CC + GSR; Hem, hemisphere; L, left; MNI (Montreal Neurological Institute) coordinates of primary peak location: X, sagittal; Y, coronal; Z, axial; R, right.
To identify significant clusters, we applied a cluster size threshold with p < .001 determined by Wild Bootstrap of 1,000 samples.
Connectivity with maximum three voxels that mark local maxima within the respective cluster; more detailed description of anatomical regions that are assigned to overall clusters and corresponding probability in Supporting Information.
