One-sample t test, p < 0.05, FWE corrected. Note that only clusters including at least 15 voxels are listed. Anatomical locations and terms were derived from the Anatomy toolbox (Eickhoff et al., 2005).
*These voxels belong to a contiguous bilateral cluster.
**Although this cluster just missed the predefined threshold of 15 voxels, it was included in the table as it reflects the bilateral organization of the lateral parietal ICN.
