Testing Protocol to Efficiently Induce Itch

Summary

This subproject aims to evaluate a new nerve excitability protocol to induce itch in healthy controls by electrical stimulation. Itch has many similarities with pain, and the nerve fibers that mediate the two sensations probably have the same morphological and excitability properties. The method used in this project will be the same as our research group uses for studying nociceptor fibers (PTT technique), but the focus is on the itch sensation. Since the itch fibers also terminate in the epidermis, our PTT technique should also be able to activate itch fibers, similar to pain fibers. If itch could be effectively induced by electrical stimulation, this would generate a valuable tool for studying itch in healthy controls. The sub-project takes place in 2 sessions (2 hours each).
