Time frequency analysis (top row). Time–frequency (TF) spectrograms for areas-of-interest within the left hemisphere. Each column is one participant, with the tenth column representing the grand average of all participants (GA). The spectrograms were obtained using Morlet wavelets averaged over the areas of C1, C3, CCP1h, FC1, FCC1h, FCC3h. Frequencies range from 2 to 40 Hz across the interval −150 ms to 150 ms. The spectrograms show the normalized difference in spectral power between the selection of right vs. left hand trials (right – left) / (right + left). The color bar represents the max and min values for each subject. (bottom row) TF in the right hemisphere averaged over the areas of C2, C4, CCP2h, FC2, FCC2h, FCC4h. The color bar units are normalized to the individual minimum and maximum
