The table shows clusters whose correlation with the corresponding ROI increased reliably with perceptual training. Pcorr, Corrected cluster-level p value related to the regressor of interest (MI); R, right; L, left. The associated z-score for the peak is shown in the z-value column. z-values pertaining and post-training give z-scores at the location of maximum activation based on values averaged over subjects in pretraining and post-training conditions respectively.
