Anatomical labels and volumes in cubic millimeter of clusters significantly in the visually guided finger movement and saccades tasks as well as in the symbolic and the non-symbolic exact addition tasks, but not in the symbolic and non-symbolic magnitude comparison tasks (depicted in blue in Figure 3) with respective Talairach coordinates (xyz) of peak values for all included tasks.
