Fig. 1. Brain networks contributing to chronic visceral pain.

Fig. 1

Schematic depiction of main brain networks identified in chronic visceral pain based on functional and structural brain imaging studies. Other brain networks including attentional and central autonomic networks are likely to be involved in the pathophysiology of chronic visceral pain syndromes, but have not been studied in detail. Reported brain abnormalities show moderate correlations with behavioral and clinical measures, even though their role in generating the subjective spontaneous pain experience remain to be determined.
