a, Illustration of cortical activation by ICMS and b, during RF mapping for a given electrode. The cortical activation by touch is much wider than that by ICMS. c, Considering the differences in cortical activation during transient and sustained phases of contact, the area of cortex activated by ICMS (AICMS) is on the same spatial scale as the hot zone (cortical activation during sustained contact - AS), but systematically smaller than the transiently activated cortical area (- AT), at a first approximation. d, Schematic of firing rate and area of activation along our recording arrays during mechanical stimulation (left and middle) compared with ICMS (right).
