EMG Crosstalk. Signal cross-correlation is displayed here using a heat map. The brighter the square, the more correlation between the two channels. A case with no crosstalk between channels would be represented by black (representing 0) everywhere aside from a diagonal white line indicating each channel’s correlation with itself. The cross-correlations computed from the participant’s chronically implanted IM-MES setup are displayed on the right, while the cross-correlations from the 8-channel ring of surface electrodes on the same residual limb are displayed on the left
