When clusters or Brodmann areas (BAs) span over more than one region, both regions/BAs are indicated, separated by a slash sign. Talairach coordinates of peak activation correspond to the local minimum P values for each cluster of activated vertices on the cortical surface.
Regions marked with ** if they also showed significant response suppression in a direct comparison between related and indirectly related word‐pairs. Clusters indicated in P column marked * if reached significance on small surface correction (P < 0.05) and/or marked # if reached cluster‐level significance (P < 0.05) across whole cortical surface. Cluster is marked † if failed to reach significance on small surface correction but reached an uncorrected voxel‐wise significance across the cortex, P < 0.05. P value indicated is the minimum P value within that cluster. NS: nonsignificant.
