Comparative analysis of power levels distributed on scalp of healthy controls. Data were based on 16 healthy controls.

Note that electrodes placed on scalp of the frontal (FP1, FP2, F3, F4, F7, F8, and Fz), temporal (T3, T4, T5, and T6), central (C3, C4, and Cz), parietal (P3, P4, and Pz) and occipital areas (O1 and O2). Significance were determined by repeated measures ANOVA followed by post hoc Scheffe test. vs. Frontal. vs. Temporal. vs. Central. vs. Parietal.
