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:
“Women hock their jewels and their husbands’ insurance policies to acquire an unaccustomed shade in hair or crêpe de chine. Why then is it that when anyone commits anything novel in the arts he should be always greeted by this same peevish howl of pain and surprise? One is led to suspect that the interest people show in these much talked of commodities, painting, music, and writing, cannot be very deep or very genuine when they so wince under an unexpected impact.”
—John Dos Passos (1896–1970)
“Yet here at least an earnest sense
Of human right and weal is shown;
A hate of tyranny intense,
And hearty in its vehemence,
As if my brother’s pain and sorrow were my own.
O Freedom! if to me belong
Nor mighty Milton’s gift divine,
Nor Marvell’s wit and graceful song.
Still with a love as deep and strong
As theirs, I lay, like them, my best gifts on thy shrine!”
—John Greenleaf Whittier (1807–1892)
“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)
