Interindividual differences in intergenerational sustainable behavior are associated with cortical thickness of the dorsomedial and dorsolateral prefrontal cortex

•In an intergenerational sustainability dilemma with real consequences, successive groups ("generations") extract resources from a common pool.•If the present "generation" exceeds a certain extraction threshold, this reduces the payoff of the next "generation".•Individual neuroanatomical fingerprints relate to interindividual differences in intergenerational sustainability.•Sustainable individuals are characterized by greater cortical thickness of the dorsomedial and dorsolateral prefrontal cortex than unsustainable individuals.•The impact of the structural findings on intergenerational sustainability is mediated by perspective-taking and self-control processes.
