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:
“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)
“Pain is real when you get other people to believe in it. If no one believes in it but you, your pain is madness or hysteria.”
—Naomi Wolf (b. 1962)
“At this very moment,... the most frightful horrors are taking place in every corner of the world. People are being crushed, slashed, disembowelled, mangled; their dead bodies rot and their eyes decay with the rest. Screams of pain and fear go pulsing through the air at the rate of eleven hundred feet per second. After travelling for three seconds they are perfectly inaudible. These are distressing facts; but do we enjoy life any the less because of them? Most certainly we do not.”
—Aldous Huxley (1894–1963)
