Somatotopic delineation for a specific movement was calculated for each channel in the following manner. The individual r2 values for each movement type were multiplied by eiπ/6 (hand), eiπ5/6 (tongue), eiπ3/2 (foot) and added together. The magnitude of the resulting complex number defines the strength of somatotopic selectivity, and the phase angle of the complex number points to the movement (or pair of movements) that the channel is somatotopically specific for. This is illustrated in Figs. ​Figs.1e1e and ​and2a.2a. Note that only channels exceeding 50% of the within-subject maximum magnitude for somatotopic selectivity are included in the plot of Fig. ​Fig.2a2a.
