Nociception and the Subjectivity of Pain
Captions available
The idea
Nociception is the neural processing of injurious stimuli; pain is its perception, and pain tolerance varies among people receiving the same nociceptive stimulus.
In practice
Capsaicin triggers pain receptors by opening the same channels warmth receptors use, without causing tissue damage.
Where people slip
Nociception at the receptor and pain as a conscious experience are distinct steps — the second does not automatically scale with the first.
