AB  - The idea of 'extended self' refers to the incorporation of personally relevant 
      external stimuli into one's concept of self. The current study used a transient 
      imagined ownership paradigm to explore brain regions that support the association 
      between self and objects. We hypothesized that incidental associations between 
      self and objects would be manifested by activation in a brain region, medial 
      prefrontal cortex (MPFC), recruited in explicit self-referential processing. We 
      further predicted that a memorial advantage for, and positivity-bias towards, 
      self-relevant objects would be related to activity in MPFC. As anticipated, MPFC 
      showed greater activation when objects were assigned to participants compared to 
      when objects were assigned to another person. Activity in MPFC was also 
      associated with superior subsequent source memory and increased preference for 
      objects assigned to the self. These findings provide neural evidence for the 
      incorporation of self-relevant objects into an extended self, which, in turn, 
      increases their judged value (mere ownership effect).
