a In participants C1 and P3, M1 electrodes are more susceptible to ICMS delivered through S1 electrodes whose projected fields match the movement fields. b When the dominant movement field matches the dominant digit in the projected field, the susceptibility is strongest; when the second most dominant movement field matches the dominant digit projected field, the susceptibility is weaker; etc. Lines denote the mean, error bars the standard error of the mean, n = 96 channels.
