(A) Glass brain and sagittal section of vmPFC and rTPJ where activity is significantly positively correlated with level of sanction value pooling intention and no-intention (vmPFC, MNI coordinate, x = 0, y = 47, z = −14; rTPJ, MNI coordinate, x = 54, y = −40, z = 7: p < 0.05, small-volume-corrected, k ≥ 10). (B) Activity of vmPFC to sanction value is significantly greater in Intention condition than in No-Intention condition (paired t-test, p < 0.025, two-tailed). Responsivity of rTPJ however is not significantly different for Intention condition and No-Intention condition (paired t-test p > 0.5, two-tailed).
