Fig. 6: Neural processes associated with reciprocity, communal concern and obligation.
From: The psychological, computational, and neural foundations of indebtedness
a Brain regions responding to trial-by-trial levels of reciprocity. b Brain regions responding parametrically to trial-by-trial communal concern, which depended on the perceived care from the help (ωB). c Brain regions identified in the parametric contrast for obligation (EB”), the responses of which monotonically increased in the Repayment possible condition relative to the Repayment impossible condition. For a–c, n = 53 participants. The brain maps were thresholded using cluster correction FWE p < 0.05 with a cluster-forming threshold of p < 0.001 121. d Results of meta-analytical decoding for the neural correlates of reciprocity, communal concern and obligation, respectively. IPL inferior parietal lobule, dlPFC dorsolateral prefrontal cortex, ITG inferior temporal gyrus, vmPFC ventromedial prefrontal cortex, aINS anterior insula, dmPFC dorsomedial prefrontal lobe, TPJ temporal parietal junction.
