AB  - Many leading theories suggest that the neural processes underlying the experience 
      of one's own emotional reactions partially overlap with those underlying bodily 
      perception (i.e., interoception, somatosensation, and proprioception). However, 
      the goal-directed maintenance of one's own emotions in working memory (EWM) has 
      not yet been compared to WM maintenance of one's own bodily reactions (BWM). In 
      this study, we contrasted WM maintenance of emotional vs. bodily reactions to 
      affective stimuli in 26 healthy individuals while they underwent functional 
      magnetic resonance imaging. Specifically, we examined the a priori hypothesis 
      that individual differences in trait emotional awareness (tEA) would lead to 
      greater differences between these two WM conditions within medial prefrontal 
      cortex (MPFC). We observed that MPFC activation during EWM (relative to BWM) was 
      positively associated with tEA. Whole-brain analyses otherwise suggested 
      considerable similarity in the neural activation patterns associated with EWM and 
      BWM. In conjunction with previous literature, our findings not only support a 
      central role of body state representation/maintenance in EWM, but also suggest 
      greater engagement of MPFC-mediated conceptualization processes during EWM in 
      those with higher tEA.
