Satiation and re-intake after partial withdrawal of gastric food contents: a dissociation effect in external lateral parabrachial lesioned rats

Highlights • Gastrointestinal (GI)vagal signals are processed through the parabrachial complex • Satiation and meal re-intake were examined after partial stomach food removal • Lesions of the external lateral nucleus (LPBe) do not affect meal satiation • However, they impair food re-intake after par...

Description
Summary:Highlights • Gastrointestinal (GI)vagal signals are processed through the parabrachial complex • Satiation and meal re-intake were examined after partial stomach food removal • Lesions of the external lateral nucleus (LPBe) do not affect meal satiation • However, they impair food re-intake after partial gastric nutrient withdrawal • LPBe appears to be critical in nutritional processes requiring rapid GI food signals
