Spatial comparison between ADM CoGs and mu-modulation centers for all subjects and both hemispheres. a While the mu-modulation centers (blue areas) are distributed around C3 and C4, the ADM CoGs (red areas) are located more medial. The intensity of the color relates to the number of ADM CoG or mu-modulation centers that overlap at a given position. The size of the red ellipses represents the localization error of the motor mapping in mediolateral and anterior-posterior direction. b Individual distances from the mu-modulation center to the ADM CoG in mediolateral and anterior-posterior direction for both hemispheres and all subjects. On average, the ADM CoG was located 1.64 cm medial (SD = 1.30 cm) and 0.31 cm anterior (SD = 1.39 cm) of the mu-modulation center on an individual level
