Topographies of 1.4–1.6 s after the task onset of the seven subjects during the 12-session BCI training in the BCI group. Two patients (OME1 and OME3) presented increasingly stronger ERD in the bilateral hemispheres as the training sessions went on. Two patients (OME4 and OME5) presented continuously strong activations (ERD) in the left ipsilesional hemisphere across most of the training sessions. Two patients (OME2 and OME7) presented weak or even no activation in the right ipsilesional hemisphere in more than six training sessions. One patient (OME6) presented ERD or ERS in the bilateral hemispheres in the 12 training sessions.
