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:
“In the small circle of pain within the skull
You still shall tramp and tread one endless round
Of thought, to justify your action to yourselves,
Weaving a fiction which unravels as you weave,
Pacing forever in the hell of make-believe
Which never is belief: this is your fate on earth
And we must think no further of you.”
—T.S. (Thomas Stearns)
“A doctor is fascinated by death, and pain. And how much pain a man can endure.”
—David Boehm, and Louis Friedlander. Dr. Richard Vollin (Bela Lugosi)
“How then can we account for the persistence of the myth that inside the empty nest lives a shattered and depressed shell of a woman—a woman in constant pain because her children no longer live under her roof? Is it possible that a notion so pervasive is, in fact, just a myth?”
—Lillian Breslow Rubin (20th century)
