Each voxel-wise analysis and the significant regions with cluster sizes, max T/F-statistics (with respective degrees of freedom) and x, y, z-coordinates in MNI space. ‘Not significant’ indicates that the results did not pass multiple comparisons correction. The final column indicates whether the cluster passed a non-parametric multiple comparisons correction (SnPM).
Not significant. See Supplementary Figure 1 for analysis of effect sizes.
