Overlapping regions between specific numerical and non-numerical tasks using inclusion and exclusion analyses: conjunction of all six tasks (red); areas commonly activated in the visually guided saccades task and the visually guided finger task in conjunction with both addition tasks but not the two magnitude comparison tasks (blue); areas exclusively activated during the saccades task but not the finger task in conjunction with both addition tasks but not the magnitude comparison tasks (green); areas activated exclusively during the finger task in conjunction with both addition tasks (orange); and areas exclusively activated during the finger task and the non-symbolic addition task (yellow). All group activations are projected onto a Talairach child template [(A) parietal activation cluster; (C) lateral frontal activation clusters; (D) subcortical activation clusters] or a single child brain in Talairach space [(B) medial frontal activation clusters; (D) subcortical activation clusters] and are significant at a cluster-threshold corrected p-value of 0.05.
