AB  - The concept of extended self refers to the idea that people incorporate 
      self-relevant others or objects into one's sense of self. Initial neural support 
      for the notion of extended self was provided by fMRI evidence that medial 
      prefrontal cortex (MPFC) showed greater activation while people imagined objects 
      belonging to them compared with someone else (Kim & Johnson, 2012). This study 
      investigated whether self-associated objects (i.e. 'mine') subsequently engage 
      MPFC spontaneously when a task does not require explicit self-referential 
      judgments. During fMRI scanning, participants detected 'oddballs' (objects with a 
      specific frame color) intermixed with objects participants had previously 
      imagined belonging to them or to someone else and previously unseen non-oddball 
      objects. There was greater activity in MPFC and posterior cingulate cortex for 
      those 'self-owned' objects that participants were more successful at imagining 
      owning compared with 'other-owned' objects. In addition, change in object 
      preference following the ownership manipulation (a mere ownership effect) was 
      predicted by activity in MPFC. Overall, these results provide neural evidence for 
      the idea that personally relevant external stimuli may be incorporated into one's 
      sense of self.
