Example of an analysis comparing ECoG signals for right hand movement and rest (modified from [36]). A: Color-coded values of r2 for all locations and frequencies. B: Average spectra (red for rest, green for right hand movement) (left) and r2 as a function of frequency (right) for electrode 15. C: Topographical distribution (black dots indicate electrode locations on the 8×4 grid) for color coded r2 values calculated for 20 Hz.
