Group maximum t-values and MNI coordinates of activation foci for the three repeated measures ANOVAs computed on the second level. Statistical maps were generally thresholded at p < 0.05 FDR corrected for multiple comparisons and FWE corrected where indicated. Results were extent threshold corrected at 0.05 at the cluster level.
