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)

—Ralph Waldo Emerson (1803–1882)
“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.”
