Fig. 3.

(a) Mean right-hemisphere mu time-frequency ERSPs (event related spectral perturbations; 7–25 Hz power, dB) as a function of condition. Event-related decreases in spectral power are represented in blue and increases are represented in orange and red. (b) Significant differences between conditions in the alpha-mu (7–12.5 Hz) and beta-mu (12.5–25 Hz) ranges. Significant values at p<0.05 after FDR correction are indicated in dark orange and non-significant values in green.
