Kind: research · Impact: medium

## In brief

- Chen et al. identify NTSNPY neurons in the brainstem as an extra-hypothalamic population that drives feeding and long-term weight gain.
- NTSNPY neurons work in parallel with the hypothalamic ARCAgRP/NPY circuits.
- The study reports that fasting-activated NTSNPY neurons are required for post-fasting feeding.

## Why it matters

It shows that energy balance is controlled by a brainstem circuit operating alongside the well-studied hypothalamic pathways, which may matter for research into obesity and appetite regulation.
