Appendix 1—figure 2. Functional connectivity within the DMN after multi-session hf-tRNS coupled with training (post-stimulation session).

Correlations of all ROI pairs (z-scores) constituting the DMN are represented separately for the three stimulation conditions (Parietal, Sham, and hMT+). No differences were found between stimulation conditions. DMN, default mode network; ROI, region of interest; tRNS, transcranial random noise stimulation
