Laterality index (LI) values were calculated using a mask that spanned the pre- and postcentral gyri (positive LI: R SMC > L SMC). BOLD percent change values are calculated from 5 voxels in the SMC (with standard deviation [SD] values). SMC = sensorimotor cortex; BOLD = blood oxygen level dependent.
