Color refers to illustration of activation distributions in Figure 2; extent refers to cluster size in voxels (1.5 × 1.5 × 1.5 mm³); area denotes the probabilistic cytoarchitectonic mapping of activations with respect to BA 44 and BA 45; numbers in parentheses refer to the proportion of the cluster within a given area.
FWE indicates family-wise error correction for multiple comparisons; unc, uncorrected for multiple comparisons.
