AbstractAlthough visceral pain is of high clinical relevance, it remains poorly understood especially when compared to somatic pain. Nevertheless, interdisciplinary research approaches bridging psychophysiology and neurogastroenterology have contributed to a more refined knowledge about the complex peripheral and central mechanisms of the bidirectional brain-gut axis in recent years. This review summarizes current knowledge regarding psychobiological mechanisms in the pathophysiology of chronic visceral pain in functional gastrointestinal disorders with a focus on irritable bowel syndrome (IBS). Special attention is paid to the role of affective disturbances and emotions, particularly psychological stress as well as to influences of cognition and learning on gastrointestinal motor and sensory functions in healthy individuals and patients with IBS. In this emerging field of research, new evidence from the fields of placebo research and pain-related fear conditioning provide new insights into the psychological and neurobiological mechanisms involved in the transition from acute to chronic pain and the maintenance of pain. This opens up new perspectives for innovative treatment approaches for IBS and other functional gastrointestinal disorders.
