A simplified characterization of the Cognitive Social Brain (CSB). Brain areas shaded in dark (pSTS, AMG, OFC) represent the core, or original, components of the CSB, and lighter shaded brain areas (TPJ, PCC, ACC, mPFC, Str, TP, and insula) represent elaborations of the CSB that have been pervasively described as important for higher-order processing of social behavior. Abbreviations: pSTS: posterior superior temporal sulcus; AMG: amygdala; OFC: orbital frontal cortex; TPJ: temporoparietal junction; PCC: posterior cingulate cortex; ACC: anterior cingulate cortex; mPFC: medial prefrontal cortex; Str: striatum; TP: temporal poles.
