AB  - Our identity consists of knowledge about our individual attributes (personal 
      identity) as well as knowledge about our shared attributes derived from our 
      membership in certain social groups (social identity). As individuals seek to 
      achieve a positive self-image, they aim at comparing favorably with other 
      individuals or their in-group comparing favorably with referent out-groups. 
      Imaging data suggest a network centered on the medial prefrontal cortex (MPFC) to 
      instantiate functions that are integral to the self, conceived as the personal 
      self. Given that the social self is constituted by the same mechanisms as the 
      personal self, we expect MPFC activation also for situations in which the social 
      self is addressed, for instance when situations permit evaluative intergroup 
      comparisons. Accordingly, participants worked on a modified version of the 
      minimal group paradigm in the present functional magnetic resonance imaging 
      experiment. Imaging data revealed activation within a network centered on the 
      dorsal MPFC specifically for social identity processes. Furthermore, this 
      activation showed correlation with the displayed in-group bias. The present 
      findings show that social and personal identity processes draw on the same 
      cerebral correlates and hence it is concluded that a network centered on the MPFC 
      subserves functions integral to the self.
