(A) A synopsis of the selected cortical hubs of interest is presented as a guide for the interpretation of results obtained from sLORETA and Granger Causality analyses. (B) Voxel t-values distributions obtained in the statistical comparison between post- and pre- NS are presented for delta (left panel), and theta (right panel). (C) Voxel t-values distributions obtained in the statistical comparison between post-NS and post-SC are presented for delta (left panel) and theta (right panel). Throughout the images, only significant voxels (p < 0.05 after SnPM correction) are represented (non-significant voxels are left uncolored). Colors range between yellow (p < 0.05) and red, the latter denoting the highest t-value among all significant voxels in the statistical image. For each band and comparison, t-values thresholds for p < 0.05, p < 0.01 and p < 0.001 are highlighted on the color bar by one, two or three asterisks respectively.
