AB  - Individualism and collectivism, or self-construal style, refer to cultural values 
      that influence how people think about themselves and their relation to the social 
      and physical environment. Recent neuroimaging evidence suggests that cultural 
      values of individualism and collectivism dynamically modulate neural response 
      within cortical midline structures, such as the medial prefrontal cortex (MPFC) 
      and posterior cingulate cortex (PCC), during explicit self-evaluation. However, 
      it remains unknown whether cultural priming modulates neural response during 
      self-evaluation due to explicit task demands. Here we investigated how cultural 
      priming of self-construal style affects neural activity within cortical midline 
      structures during implicit self-evaluation in bicultural individuals. Results 
      indicate that ventral MPFC showed relatively less deactivation during implicit 
      evaluation of both self- and father-relevant information as compared to control 
      condition (e.g., information of an unfamiliar person), irrespective of cultural 
      priming. By contrast, dorsal MPFC showed relatively less deactivation during 
      implicit evaluation of father-relevant information, but not self-relevant 
      information, as compared to control condition, only when they were primed with 
      individualism. Furthermore, dorsal MPFC showed relatively less deactivation 
      during implicit evaluation of father-relevant information as compared to 
      self-relevant condition only when they were primed with individualism. Hence, our 
      results indicate that cultural priming modulates neural response within dorsal, 
      but not ventral, portions of MPFC in a stimulus-driven rather than task-driven 
      manner. More broadly, these findings suggest that cultural values dynamically 
      shape neural representations during the evaluation, rather than the detection, of 
      self-relevant information.
