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:
“Crude thoughts and fierce forces are my state. I do not know who I am. Nor what I was. I cannot hear a sound. Pain is near that will be like no pain felt before.”
—Norman Mailer (b. 1923)
“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)
“Poverty is relative, and the lack of food and of the necessities of life is not necessarily a hardship. Spiritual and social ostracism, the invasion of your privacy, are what constitute the pain of poverty.”
—Alice Foote MacDougall (1867–1945)
