This study began development of a new communication and control modality for individuals
with severe motor deficits. We trained normal subjects to use the 8–12 Hz mu rhythm
recorded from the scalp over the central sulcus of one hemisphere to move a cursor from the
center of a video screen to a target located at the top or bottom edge. Mu rhythm amplitude
was assessed by on-line frequency analysis and translated into cursor movement: larger
amplitudes moved the cursor up and smaller amplitudes moved it down. Over several�…
