Notes.
a
p<0.001
b
p < 0.01
c
p< 0.05, - indicates non-significant results. Regions were isolated from featural (F), first-order (1), or second-order (2) face processing. INS: insula; IFG: inferior frontal gyrus; L: left; R: right; SPL: superior parietal; FFA: fusiform face area; SFG: superior frontal gyrus. Size is in voxels with spatial resolution of 2 × 2 × 2 mm. Minimum cluster extent for each individual contrast prior to logical combination was 225 to 305 voxels (Z > 3.1). However, cluster sizes could be smaller than this after logical intersection.
