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)
“If anything ail a man, so that he does not perform his functions, if he have a pain in his bowels even,—for that is the seat of sympathy,—he forthwith sets about reforming—the world.”
—Henry David Thoreau (1817–1862)
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
