Fig. 3: Topographic plots of the t-value comparisons with channels that passed the False discovery rate (FDR) correction in relative power values for delta, theta, and alpha frequency bands.

Black dots represent each of the 19 channels and are arranged according to the 10–20 system. Color bars represent the t-values. The leftmost column compares controls to AD, the middle column compares controls to FTD, and the rightmost column compares AD to FTD.
