Fig. 4: Functional connectivity.

Whole-brain functional connectivity after 30 sessions of optimized multichannel tDCS compared to sham tDCS. PLV and coherence values were used to quantify functional connectivity changes in the brain related to cognitive impairment and emotional regulation. No significant post-intervention differences were observed between conventional and sham tDCS. Red edges represent an increase in functional connectivity between nodes. Node colors denote anatomical regions- Frontal (Red), Central (Yellow), Parietal (Green), Occipital (Cyan), and Temporal (Dark Blue). The color bar indicates t-values from permutation statistics (red: significant increase in connectivity).
