Fig 4. EEG power topographies.

Fig 4

Upper panel: Changes in EEG delta power after HD-tDCS treatment. From left to right: average referenced EEG delta power topographies before (EEG #1) and after (EEG #4) HD-tDCS, differences between the two, and SPM and SNPM T maps. T maps are thresholded for display at uncorrected p<0.05. A rainbow color scale is used for SWA, and a hot color scale for T values. Lower panel: Correlation between changes in EEG delta power and improvements in ImpACT scores after HD-tDCS. From left to right: slope of multiple regression between changes in EEG delta power and improvements in ImpACT scores; SPM and SNPM T maps; and distribution plot for the statistical peaks of correlation analysis. T maps are thresholded for display at uncorrected p<0.05. A rainbow color scale is used for regression slope values, and a hot color scale for T values.
