Human: duodenum, colon of bitter tastants induced the secretion of the hunger secretion of ghrelin with functional effects on food intake and gastric emptying. Consequently, the local activation of the taste receptor stimulates the search for food and food intake through the action of ghrelin this effect is obviously temporary when food fills the stomach, gastric emptying is temporarily inhibited and the search for food limited.

Objectives: intragastric bitter tastants may decrease appetite and food intake we aimed to investigate the gut-brain signaling and brain mechanisms underlying these effectsmethods: brain responses to intragastric quinine-hydrochloride (qhcl, 10 µmol/kg) or placebo infusion were recorded using functional magnetic resonance imaging in 15 healthy women.
