Alloknesis Is Sensitisation
The claim
Whether a light touch becomes itchy is set by the ratio of central sensitisation to peripheral input, so the same touch is neutral in one state and unbearable in another.
01Mechanism
Sensitisation lowers the threshold for pruriceptors to respond to touch; the ratio determines whether touch crosses it.
02Prediction
Alloknesis should track the ratio.
03Refutation
Alloknesis tracking touch strength would remove sensitisation.
