From Gut Peptides Through Enteric Nerves to Brain: The Complete Appetite Signaling Chain

Appetite signaling flows from gut peptides through enteric nerve networks to brainstem and hypothalamic circuits, with the vagus nerve as the primary conduit — the complete neural-humoral pathway from food to brain decision.

What This Study Found

The appetite signaling chain: food → gut peptide release (GLP-1, PYY, CCK, ghrelin) → enteric nerve detection → vagal afferent transmission → brainstem integration (NTS) → hypothalamic processing (arcuate) → behavioral output — the complete food-to-decision neural-humoral pathway.
