The Case Against the Experience of Pain in the Fish

James Rose of the University of Wyoming has put forth a strong argument for the inability of fish to experience pain that relies on analogy between human and fish neuroanatomy. Rose emphasizes the distinction between reaction to injury and psychological experience of pain and emphasizes that the existence of the former does not evince the existence of the latter. Indeed, human experiments have proven that pain is experienced in the brain and that sensation of and reaction to noxious, or potentially harmful, stimuli can occur without the experience of pain. The concept of nociception makes this possible.
