  • Coordinates (x, y, z) are reported in Talairach space (Talairach and Tournoux, 1988); t values are computed across all voxels within the activated cluster. BA, Brodmann area; L, left; R, right; STG, superior temporal gyrus; IFG, inferior frontal gyrus; MFG, medial frontal gyrus; Fus, fusiform gyrus; MTG, middle temporal gyrus; SFG, superior frontal gyrus; Precun, precuneus; SPL, superior parietal lobule; IPL, inferior parietal lobule.
