Abstract
Interoceptive visceral pain is perceived as more fear-inducing and unpleasant compared to cutaneous heat pain in healthy women even when stimuli are matched for perceived pain intensity. On a neural level, both pain stimuli induce comparable neural activation in areas related to processing of sensory-discriminative pain aspects. However, enhanced neural responses are observed in areas associated with salience processing and descending pain inhibition for the visceral pain modality, even when results are controlled for intra-individual differences in perceived pain intensity. Moreover, immanent fear of pain is suggested to play a distinctive role in perception of visceral pain.
