AB  - The self-concept consists of both a general (context-independent) 
      self-representation and a set of context-dependent selves that represent personal 
      attributes in particular contexts (e.g., as a student, as a daughter). To date, 
      however, neuroimaging studies have focused on general self-representations, such 
      that little is known about the neural correlates of context-dependent 
      self-knowledge. The present study aimed at investigating this issue by examining 
      the neural correlates of both kinds of self-knowledge. Participants judged the 
      extent to which trait adjectives described their own personality or the 
      personality of a close friend, either in a specific context (i.e., as a student) 
      or in general. We found that both kinds of self-judgments were associated with 
      common activation in the medial prefrontal cortex (MPFC), as compared to 
      judgments about others. Interestingly, however, there were also notable 
      differences between self-judgments, with context-independent judgments being 
      associated with higher activity in the MPFC, whereas context-dependent judgments 
      were associated with greater activation in posterior brain regions (i.e., the 
      posterior cingulate/retrosplenial cortex). These findings show that 
      context-independent and context-dependent self-referential judgments recruit both 
      common and distinct brain regions, thereby supporting the view that the 
      self-concept is a multi-dimensional knowledge structure that includes a general 
      self-representation and a set of context-specific selves.
