The table shows clusters whose correlation with the corresponding ROI changed reliably with motor learning. pcorr is the corrected cluster-level p value related to the regressor of interest (PI). The associated Z score for the peak is shown in the Z value column. Z value day1 and Z value day 2 give Z scores at the location of maximum activation based on values averaged over subjects on days 1 and 2, respectively. A negative Z score indicates an anti-correlation between the ROI time series and the time series of activation peak. L, Left; R, right; SFG, superior frontal gyrus.
