State
Nociception is the neural processing of injurious stimuli; pain is its perception, and pain tolerance varies among people receiving the same nociceptive stimulus.
Show
Capsaicin triggers pain receptors by opening the same channels warmth receptors use, without causing tissue damage.
Watch for
Nociception at the receptor and pain as a conscious experience are distinct steps — the second does not automatically scale with the first.
