Table A1.

ROI information for each participant. Peak coordinates (MNI) for the functional ROIs in the left IFG and left MTG/STG and t value of peak activation for all participants (n = 50). Corresponding age group: younger/older based on median-split. Percentage of voxels showing activation in left IFG Opercularis (OP), Triangularis (TR) and Orbitalis (OR) and in left MTG and STG.
