The ANOVA of gamma responses revealed significant differences for training, F(3,72) = 3.43, p = 0.022, ηP2 = 0.13. Post hoc comparisons showed that the spontaneous EEG gamma power was increased in the video control condition, than in mental, p = 0.03, and physical Qigong practice, p = 0.02, and at baseline rest, p = 0.04. Significant differences were found for experimental conditions (eyes-open, eyes-closed), F(1,24) = 5.45, p = 0.028, ηP2 = 0.19. The ANOVA of gamma responses revealed significant results for training × condition, F(3,72) = 3.04, p = 0.034, ηP2 = 0.11. Post hoc comparisons showed that gamma activity was increased in the video control condition in eyes-open compared to eyes-closed condition, p = 0.031. The ANOVA of gamma responses revealed significant differences between locations, F(4,96) = 2.83, p = 0.029, ηP2 = 0.11. Post hoc comparisons showed that spontaneous EEG gamma power at temporal electrodes was increased compared to frontal, p = 0.02, central, p = 0.03, parietal, p = 0.03, and occipital electrodes, p = 0.03.
