Figure 2: Results for the normalized Pre-Post Power, frequency and coherence changes of 1mA active group vs sham group 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 scalp maps at the top row show the percentage of change between PRE and POST stimulation for the Sham group; the scalp maps in the middle row show the bottom map show the percentage of change between PRE and POST for the active 1mA group; and the scalp maps in the bottom row provide the p-value (Wilcoxon test) of active 1mA group versus Sham.
