Group-average BOLD time-courses. Individual participants’ ROI time-courses (an average of the voxel time-courses of the ROIs) were average to yield group-average-time course. Percent-of-signal-change in BOLD-signal over time is used as the measure of the time-course. The grey background indicates the stimulation period. Confidence intervals of 95% are shown in colored shadings. Note that SI and SII cortices are always contralateral to the stimulated limb. * denotes p < 0.05 and ** denotes p < 0.01 in peak-BOLD-response amplitude between the groups (TD n = 23 and CP n = 18). Note the difference between the mean time-course sample size (CP group n = 17) and statistical test sample size (CP group n = 18) in CP as different sample sizes were used by using imputation for statistical testing.
