Kind: research · Impact: low

## In brief

- Neural mechanisms underlying itch are not fully understood, according to the authors.
- The study reports a circuit from the posterior paraventricular nucleus of the thalamus to the medial shell of the nucleus accumbens (pPVT-NAcMed).
- The authors show that this circuit mediates an anti-pruritic (anti-itch) response.

## Why it matters

The work identifies a specific thalamus-to-accumbens pathway involved in suppressing itch, which adds to the understanding of how the brain controls itch. The findings come from mouse studies, so their relevance to human itch remains to be tested.
