AB - 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 weeks, subjects learned to change mu rhythm amplitude quickly and
accurately, so that the cursor typically reached the target in 3 sec. The
parameters that translated mu rhythm amplitudes into cursor movements were
derived from evaluation of the distributions of amplitudes in response to
top and bottom targets. The use of these distributions was a distinctive
feature of this study and the key factor in its success. Refinements in
training procedures and in the distribution-based method used to translate
mu rhythm amplitudes into cursor movements should further improve this
1-dimensional control. Achievement of 2-dimensional control is under
study. The mu rhythm may provide a significant new communication and
control option for disabled individuals.
