AB  - People typically demand more to part with goods they own than they would be 
      willing to pay to acquire identical goods they do not own, a phenomenon known as 
      the endowment effect [1-3]. Recently, a large body of behavioral research has 
      suggested that the endowment effect may actually be a type of self-referent 
      cognitive bias resulting from ownership of an object. However, the neural 
      underpinnings of this effect are not well understood. In the present study, we 
      used functional magnetic resonance imaging (fMRI) to explore whether brain 
      activity can predict the extensibility of the endowment effect to items owned by 
      another individual with a close relationship to the subject. Subjects were asked 
      to decide whether to buy or sell their own or their mothers' possessions at 
      various prices. Behavioral results showed an endowment effect not only for goods 
      owned by the subjects, but also for goods owned by the subjects' mothers, 
      providing evidence for the extensibility of the endowment effect. Neuroimaging 
      data showed activation in the medial prefrontal cortex (MPFC) and insula in both 
      ownership conditions. Also, MPFC activation was positively correlated with the 
      behavioral indifference point in the sell-for-self and sell-for-mother 
      conditions. Furthermore, psychophysiological interaction (PPI) analysis revealed 
      that MPFC activation was accompanied by increased functional integration with 
      insula and striatum. Together, these findings suggest that MPFC may play an 
      important role in the extensibility of the endowment effect.
