The effect of taste on gastric and pancreatic responses in dogs.
Other Article (Journal Article)
Six mongrel dogs with gastric and esophageal fistulas (n = 4) or with gastric and pancreatic fistulas (n = 2) were studied to determine the role of taste on gastric and pancreatic secretion. Stimulation of the back of the throat with a range of tastants produced gastric acid, bicarbonate, protein, and pancreatic polypeptide levels that were statistically equivalent to those produced with stimulation of the entire tongue. This suggests that the vagus nerve is the primary mediator of the cephalic phase response to tastants. There were marked individual differences among dogs in the responses to the ten tastants that were tested. On average, monosodium glutamate and seltzer, which mongrel dogs do not normally encounter in their diets, produced lower gastric acid secretion and pancreatic polypeptide release than sweet, sour, salty, bitter, and meaty tastes. The gastric acid secreted by the dogs with esophageal fistulas in response to tastes was only one-half as large as levels previously reported for sight/smell of food and only one sixth as large as those obtained with sham feeding.
