Data processing stream overview adapted from Kabbara et al.41. Blue box: Determination of frontal midline theta with independent component analysis. The average component was localized within Brodman Area (BA) 24. Power spectrum density (Welch method) was used to extract relative power over the whole epoch. Orange box: Preprocessing steps and selection of epochs for source connectivity and power analysis in the Default Mode Network (DMN). Green box: Preprocessing of native MRI and co-registration with the electrode coordinates. AMICA adaptive mixture independent component analysis, ICA independent component analysis, wMNE weighted minimum norm estimation, BEM boundary element model, PLV phase locking value.
