      round-robin fMRI study.

AB  - Humans continually form and update impressions of each other's identities based 
      on the disclosure of thoughts, feelings, and beliefs. At the same time, 
      individuals also have specific beliefs and knowledge about their own 
      self-concept. Over a decade of social neuroscience research has shown that 
      retrieving information about the self and about other persons recruits similar 
      areas of the medial prefrontal cortex (MPFC), however it remains unclear if an 
      individual's neural representation of self is reflected in the brains of 
      well-known others or if instead the two representations share no common 
      relationship. Here we examined this question in a tight-knit network of friends 
      as they engaged in a round-robin trait evaluation task in which each participant 
      was both perceiver and target for every other participant and in addition also 
      evaluated their self. Using functional MRI and a multilevel modeling approach, we 
      show that multivoxel brain activity patterns in the MPFC during a person's 
      self-referential thought are correlated with those of friends when thinking of 
      that same person. Moreover, the similarity of neural self-other patterns was 
      itself positively associated with the similarity of self-other trait judgments 
      ratings as measured behaviorally in a separate session. These findings suggest 
      that accuracy in person perception may be predicated on the degree to which the 
      brain activity pattern associated with an individual thinking about their own 
      self-concept is similarly reflected in the brains of others. (PsycINFO Database
