Four main types of visceral stimuli have been employed in experimental studies on visceral nocicpetion: (1) electrical, (2) mechanical, (3) ischemic, and (4) chemical. Studies of visceral pain are discussed in relation to the use and ‘adequacy’ of these stimuli and the responses produced (e.g., behavioral, pseudoaffective, neuronal, etc.). We propose a definition of an adequate noxious visceral stimulus and speculate on spinal mechanisms of visceral pain. © Lippincott-Raven Publishers.
