The Electrical Brain Circuits That Control Eating: How Hunger and Satiety Neurons Talk
Electrophysiological studies of hypothalamic feeding circuits reveal how NPY/AgRP hunger neurons and POMC/CART satiety neurons interact electrically, with ghrelin, leptin, and insulin modulating their firing patterns.
Quick Facts
What This Study Found
Hypothalamic feeding circuits operate through electrophysiological excitation of NPY/AgRP neurons (hunger) and inhibition of POMC/CART neurons (satiety), with peripheral signals (ghrelin, leptin, insulin) directly modulating neuronal firing patterns.
