Pain
While large mechanosensory neurons such as type I/group Aß display adaptation, smaller type IV/group C nociceptive neurons do not. As a result, pain does not usually subside rapidly but persists for long periods of time; in contrast, one quickly stops receiving touch or sensory information if surroundings remain constant.

Famous quotes containing the word pain:
“For pain is perhaps but a violent pleasure? Who could determine the point where pleasure becomes pain, where pain is still a pleasure? Is not the utmost brightness of the ideal world soothing to us, while the lightest shadows of the physical world annoy?”
—Honoré De Balzac (1799–1850)
“Each body has its art, its precious prescribed
Pose, that even in passion’s droll contortions, waltzes,
Or push of pain or when a grief has stabbed,
Or hatred hacked is its, and nothing else’s.”
—Gwendolyn Brooks (b. 1917)
“He has no resolution, he shrinks from pain or labour in any of its shapes. His very attitude bespeaks this: he never straightens his knee joints, he stoops with his fat ill- shapen shoulders, and in walking he does not tread but shovel and slide.”
—Thomas Carlyle (1795–1881)
