Group EEG characteristics during initial neurological assessment of end users. a Group average ERSP of left and right hand attempted movement in 8–24 Hz frequency band. On the electrode map on the far right electrode locations with statistically significant differences between the two conditions are marked with red dots (C3 and CP4). b Corresponding group average spectrograms of right and left hand attempted movement. Top row: electrode locations C3, CZ, and C4 during right hand attempted movement; bottom row: electrode locations C3, CZ, and C4 during left hand attempted movement. Above the C3 plot in the top row is a schematic representing what the SCI user was shown on screen (blank black screen, cross only, or cross and arrow to right or left), and what actions were performed during the trial (resting or AM). This sequence applies to all six plots
