Persistence of sham feeding after intragastric meals in the rat: Concentration-intake relations
Tóm tắt
In rats sham fed through esophageal fistulas, responsiveness to sucrose over a range of concentrations was assessed under two conditions: immediately following a large intragastric (IG) preload of liquid diet, and after 10 h of deprivation with no preload. The preload had no reliable effect on sucrose sham feeding at any sucrose concentration. Therefore, the insensitivity of sham feeding to IG loads is not confined to intense or highly palatable oral stimuli, but extends even to minimally effective ones.
