The phenomenon is "extreme" in a disease that is typically associated with faulty Na-sub-V-1-point-7 channels resulting from a defect in the SCN9A gene. A mutation of the TkrA gene is thought to cause a congenital defect, often associated with anhydrosis, in which the body does not perceive it, a condition called CIPA. Melzack and Wall proposed the "gate control theory" of this phenomenon. The "fast" version of this phenomenon propagates via A-delta fibers, contrasted with the slower version that uses C fibers, which are atypically unmyelinated. The McGill Questionnaire and Wong-Baker FACES are designed to measure the extent of this phenomeno

The McGill Questionnaire and Wong-Baker FACES are designed to measure the extent of this phenomenon. This phenomenon results from the actions of sensory nerves called nociceptors, and redheads are notably more sensitive to some varieties of it. Allodynia is the unusual sensation of this phenomenon, the decreased sensitivity to which is dubbed hypoalgesia. For 10 points, name this sensation blocked by anesthetics, the body's response to harmful stimuli.
