For all ROIs, we report uncorrected t statistics and relative uncorrected p values, plus small volume corrected (SVC) Z statistics and corrected p values. Significant statistics have p < .05 SVC and are marked with asterisks. Cluster size is reported using a threshold of p < .005 uncorrected. Pearson correlation coefficients are also reported for correlation analyses.
