Stereotaxic coordinates (mm) are derived from the human brain atlas of Talairach and Tournoux 1988. Brodmann area (BA) designations are also based on this atlas.
a, anterior; m, middle; p, posterior; FO, frontal operculum; IFG, inferior frontal gyrus; INS, insula; IPS, intraparietal sulcus; IPL, inferior parietal lobule; ITS, inferior temporal sulcus; MFG, middle frontal gyrus; MTG, middle temporal gyrus; SFG, superior frontal gyrus; SFS, superior frontal sulcus; SPL, superior parietal lobule; STG, superior temporal gyrus; STS, superior temporal sulcus. Right hemisphere regions of interest (ROIs) were generated by reflecting the left hemisphere location across the midline.
