In order to evaluate the connectivity in the DMN, 12 Regions of Interest (ROIs) were defined according to Thatcher and coworkers14 (Table 2). These Authors selected the Brodmann’s areas involved in the DMN on the basis of the review by Buckner et al.13. The ‘single nearest voxel’ option was chosen because eLORETA has low spatial resolution, and the single centroid voxel is considered an excellent representative of the ROI37. In this way, each ROI consisted of a single voxel, the closest to each seed.
