Social Concepts Are Represented in the Superior Anterior Temporal Cortex

Abstract social concepts such as ‘honesty,’ ‘courage,’ or ‘betrayal’ are the building blocks of moral reasoning and social judgment, yet the neural substrate that supports their representation had not been identified prior to this study. Using functional MRI combined with neuropsychological evidence from patients with focal brain lesions, the authors demonstrate that the superior anterior temporal cortex (BA38/22) is selectively engaged by social conceptual content, functioning as a dedicated neural hub for the representation of abstract knowledge about social behavior. This finding establishes a critical link between semantic cognition and moral cognition, showing that the same region that processes conceptual social meaning also supports the higher-order representations that underlie value-laden judgments. The identification of this cortical substrate has since informed research on social concept impairments in neurodegenerative diseases and the neural organization of the human moral mind.
