Figure 5

The layout of active channel patterns across all 32 recording electrodes during reach-return movements. Active channels corresponding to low-, intermediate-, and high-frequency bands before (left panels) and after (right panels) the onset of the movement (middle line). Channels are arranged to match the topographic map of ECoG electrodes (dorsal-to-ventral from left-to-right) shown at the bottom-left. The copper color bar 0-1 represents how strongly the relative power deviates from the baseline activity; 0 correspond to |Z-Score| of 2 whereas 1 represents |Z-score| ≥3. The number of active channels is reported below each panel. (Upper row: Reach, Middle row: Return, Lower row: Reach-Return movement SNR).
