Posterior middle frontal gyrus	R	28, 13, 52
Anterior inferior parietal lobule	L	−43, −59, 50
Anterior inferior parietal lobule	R	44, −60, 49
Posterior inferior parietal lobule	L	−34, −77, 42
Posterior inferior parietal lobule	R	42, −72, 37

The table lists the regions that were most significantly active during the working memory (1-back and 2-back) conditions compared to the control condition (functional contrast of [2-back/2 + 1-back/2] > Compare). The peak coordinates are reported in MNI space (LPI/SPM) and refer to the voxel with the greatest positive activation.
