The schematic of the value-based framework for cooperation (a) shows known modulatory inputs affect the computation of cooperative value. These inputs include goals and control, expectations and norms, social cognition, memory, and visual attention. These factors are implemented in various regions shown in the brain image and modulate the value system, which is implemented in the ventromedial prefrontal cortex (VMpfc) and ventral striatum. Decisions to cooperate are based, in part, on social trust (b), which is influenced by identities, social networks, and social institutions. DLpfc = dorsolateral prefrontal cortex; ACC = anterior cingulate cortex; Ins = anterior insula; VLpfc = right lateral prefrontal cortex; TPJ = temporoparietal junction; STS = posterior superior temporal sulcus.
