Neuropeptide Y is crucial for nutritional state-dependent regulation of maternal behavior

Highlights • Fasting for 9 h disrupt the expression of maternal behavior in mice. • NPY modulates neuronal activity in the DRN via the Y1 receptor. • NPY inhibits both 5-HT neuronal activity and its modulation via the GABA receptor. • NPY signaling in the DRN mediates fasting-induced inhibition of m...
