The paper compares mechanical pain discrimination between the hand and foot, finding the foot performs better, which cannot be explained by peripheral nociceptor activity.

The paper identifies PIEZO2-dependent mechanical pain in humans and mice, showing hair-pull pain is mediated by Aβ inputs and specific nociceptors.

The paper shows that burst gap coding, previously observed in mechanical stimulation, also applies to electrical nerve stimulation, influencing tactile frequency perception through temporal spike patterns.
