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:
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
“Indeed, there are no easy correlations between parental ideology, class or race and “successful” child development. Many children the world over have revealed a kind of toughness and plasticity that make the determined efforts of some parents to spare their children the slightest pain seem ironic.”
—Robert Coles (20th century)
“This is a pain I mostly hide,
but ties of blood, or seed endure,
and even now I feel inside
the hunger for his outstretched hand,
a man’s embrace to take me in,
the need for just a word of praise.”
—Jimmy Carter (James Earl Carter, Jr.)
