Grand average of evoked hemodynamic changes in all three conditions in the two short‐distance channels (channels 2 and 10) before the application of the short separation regression. (A–C): Short‐distance channel in the supplementary motor area (SMA) in the brushing condition (A), in the nonpainful condition (B), and in the painful condition (C). (D–F): Short‐distance channel in the primary somatosensory cortex (S1) in the brushing condition (D), in the nonpainful condition (E), and in the painful condition (F)
