Figure 2

Activity in DLPFC and DMPFC (seed regions for Fig. 3) reflects truthtelling costs with increasing propensity to be honest.
(A,B) DLPFC responses to the cost of truthtelling increased with the individual percentage of truthtelling (−30, 56, 26; t(30) = 4.92; p < 0.05, whole-brain FWE cluster-level corrected). (C,D) DMPFC responses to the cost of truthtelling increased with the individual percentage of truthtelling (−6, 16, 44; t(30) = 4.48; p < 0.05, whole-brain FWE cluster-level corrected). Throughout, activations are displayed at the uncorrected level of p < 0.001 for visualisation purposes.
