Brain areas activated under each condition.

<p>(A) Red areas showed greater activation in the task than in the rest period. LC: the larger digit choice; SC: the smaller digit choice; LD: Large distance; SD: Small distance. The threshold <i>p</i>-value under each condition was 0.001 (uncorrected). (B) Comparison between the brain areas that were activated under the SC and LC conditions with <i>p</i>-values lower than 0.001 (uncorrected). The number at the upper left of the picture in each section indicates the <i>y</i>-level on the MNI coordinates. (CUN: cuneus/precuneus, TPJ: temporo–parietal junction, INS: insula, ACC: anterior cingulate cortex, SFG: superior frontal gyrus, STS: superior temporal sulcus, PreCG: precentral gyrus).
