Fig. 5: Connectivity analysis results.

a Stronger connectivity between the left vmAI and right ACC for self-gain lies with reputation vs. no reputation risks (yellow vs. blue bar) and for other-gain truths with no reputation vs. reputation risk (red vs. purple bar). b Stronger connectivity between the left vmAI and left ACC for self-gain lies with reputation vs. no reputation risks (yellow vs. blue bar) and for other-gain truths with no reputation vs. reputation risk (red vs. purple bar). c Stronger connectivity between the right ACC and left dmPFC for self-gain lies with reputation risk vs. other conditions (yellow vs. blue, red, and purple bars). vmAI ventromedial anterior insula, ACC anterior cingulate cortex, dmPFC dorsomedial prefrontal cortex, NoRep_SG-Lie self-gain lies without reputation risk, NoRep_OG-Truth other-gain truths without reputation risk, Rep_SG-Lie self-gain lies with reputation risk, Rep_OG-Truth other-gain truths with reputation risk.
