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)
“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)
