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:
“Pain itself can be pleasurable accidentally in so far as it is accompanied by wonder, as in stage-plays; or in so far as it recalls a beloved object to one’s memory, and makes one feel one’s love for the thing, whose absence gives us pain. Consequently, since love is pleasant, both pain and whatever else results from love, in so far as they remind us of our love, are pleasant.”
—Thomas Aquinas (c. 1225–1274)
“Pain hardens, and great pain hardens greatly, whatever the comforters say, and suffering does not ennoble, though it may occasionally lend a certain rigid dignity of manner to the suffering frame.”
—A.S. (Antonia Susan)
“Hush! Check those words. Do not cure ill with ill and make your pain still heavier than it is.”
—Sophocles (497–406/5 B.C.)
