Figure 2: Results for the normalized Pre-Post Power changes of 1mA vs sham show a) significant increase of the mean power domain in Gamma frequency band under C3, the anodal stimulating electrode. b) A significant increment of faster activity around the anodal stimulating electrode (C3, F3) while a decreased mean frequency in the Alpha band near the return electrode (P4) and c) significant increased mean coherence in the fastest frequency bands (Beta2, Gamma) and SMR under the stimulating electrode (C3), the symmetrical location in the other hemisphere (C4) and the vertex (Cz). The bottom map provides the p-value (Wilkoxon test) of Sham vs. active stimulation.
