Fine Hair Has Its Own Itch Circuit
Researchers traced mechanical itch to fine hairs, specialized nerve cells, and a dedicated spinal pathway.
Summary
Researchers traced mechanical itch to fine hairs, specialized nerve cells, and a dedicated spinal pathway.
A newly described sensory network links fine body hairs to specialized neurons that respond to light mechanical irritation. Animal experiments and signs of a comparable human pathway suggest mechanical itch is processed through a more dedicated circuit than previously recognized. The work may clarify chronic itch mechanisms, but it does not yet provide a treatment.
