Figure 2: Brain regions activated by the AP and EX addition task in the abacus-trained and nontrained group. (a) The activity pattern revealed by the AP addition task in the abacus-trained group. (b) The activity pattern revealed by the EX addition task in the abacus-trained group. (c) The activity pattern revealed by the AP addition task in the nontrained group. (d) The activity pattern revealed by the EX addition task in the nontrained group. The left column showed the right hemisphere; the middle showed the left hemisphere, and the right showed the vertical view of the brain. ( , FDR corrected; minimal cluster size = 30 voxels).
