Figure 8

Group averagemaps for the motor and premotor areas as recorded by ECoG for cued index finger movements (n = 7). The left figure shows the Z-score map for the premotor electrodes. The middle figure shows motor activity. The band power maps for each subject have been converted to Z-scores, based on the −1 s to −0.6 s interval, prior to averaging. A threshold of ‖Z‖ ≥ 3 is used for both areas, corresponding to 8 std of the baseline. The right figure shows the mean data glove output across all subjects. Our ECoG shows premotor/motor HG activity patterns that are similar to our EEG.
