Left : Grand average of feedback performance within each run (horizontal bars and dots for each group of 20 trials) for subjects of Category I ( N = 6), Category II ( N = 2) and Category III ( N = 3). An accuracy of 70% is assumed to be the threshold required for BCI applications. Right: For one subject of Category III spectra in channel CP3 and scalp topographies of band-power differences (signed r2-values) between the motor imagery conditions are compared between the beginning (runs 1+2) and the end (runs 7+8) of the experiment.
