Parameters associated with all hand and tongue movement findings

Motor modality	Hand	Tongue
Total electrodes	892	764
Number of high band electrodes	75	85
Mean high band y position	−15 ± 11	−6 ± 13
Mean high band z position	50 ± 11	31 ± 19
Number of low band electrodes	172	129
Mean low band y position	−15 ± 14	−6 ± 14
Mean low band z position	50 ± 14	39 ± 18

The position values refer to Talairach standardized coordinates (Talairach and Tournoux, 1988) (in mm), and the x coordinates are omitted because data from the lateral surface of both hemispheres has been combined. The ± symbol denotes SD in position (square-root of the variance).
