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:
“His pain was too great. He begged me for the simple mercy of death. And I could do nothing else but help him leave a world that had become a sleepless, tortured nightmare to him.”
—Robert D. Andrews, and Nick Grindé. Dr. John Garth (Boris Karloff)
“If anything ail a man, so that he does not perform his functions, if he have a pain in his bowels even,—for that is the seat of sympathy,—he forthwith sets about reforming—the world.”
—Henry David Thoreau (1817–1862)
“The years of imprisonment hardened me.... Perhaps if you have been given a moment to hold back and wait for the next blow, your emotions wouldn’t be blunted as they have been in my case. When it happens every day of your life, when that pain becomes a way of life, I no longer have the emotion of fear. ... there is no longer anything I can fear. There is nothing the government has not done to me. There isn’t any pain I haven’t known.”
—Winnie Mandela (b. 1936)
