TL;DR
Gastric preloads of glucose solution promote resting to reinstate the "satiety sequence" after a bout of saccharin ingestion, and the systemic effects of glucose are sufficient to promote resting.
Abstract
Hungry rats display the characteristic "satiety sequence" after drinking a glucose solution: The end of ingestion is accompanied by grooming and exploring, followed by resting. With saccharin solutions over a range of concentrations, however, ingestion is accompanied and followed by persistent grooming and exploring; resting rarely occurs. Gastric preloads of glucose solution promote resting to reinstate the "satiety sequence" after a bout of saccharin ingestion. Therefore, the systemic effects of glucose are sufficient to promote resting. In the absence of postingestive factors, the "satiety sequence" is incomplete following saccharin ingestion as it is after sham-feeding.

Seven major types of sampling for observational studies of social behavior have been found in the literature and the major strengths and weaknesses of each method are pointed out.

The observation that cholecystokinin not only stops feeding but elicits the complete sequence of satiety supports the hypothesis that endogenous cholecentokinin is a satiety signal for the rat.

This work suggests, but does not prove, that cholecystokinin mediates intestinal satiety in the rat, and calls the satiety elicited by the infusion of food into the duodenum "intestinal satiety," which emphasizes the belief that satiety is a reflex that can be eliciting by the activation of receptors in the wall of the intestine.

These experiments show that pregastric food-contingent stimuli -alone (sham feeding) are sufficient for the termination of a meal, appearance of postprandial resting behavior and for a measurable IMI under conditions resembling those of normal feeding for laboratory rats in the light phase of a diurnal cycle.

The results of these studies support the view that McCleary's osmotic postingestional satiety signal acts as an intestinal distention signal rather than by inducing thirst.
Physiology & BehaviorLicking rate of rats is reduced by intraduodenal and intraportal glucose infusion☆

Control infusions of isotonic NaCl into the portal vein indicate that the depressing effect of portal glucose and urea on licking rate was chemospecific rather than due to local hypervolemia.
AppetiteRelease of feeding by the sweet taste in rats: Oropharyngeal satiety
48 Citations1980Douglas G. Mook, Claudia Bryner +2 more
In rats which are hungry but not thirsty, the intake of a saccharin solution occurs in discrete “meals”, and oropharyngeal factors can initiate, and also terminate, a “meal” under these special conditions.
AppetiteRelease of Feeding by the Sweet Taste in Rats: The Influence of Body Weight
42 Citations1981Douglas G. Mook, Carol Lynn Cseh
It is shown that intake of sweet solutions is sensitive to nutritional status, suggesting that the rats are treating the solutions as liquid diets and “eating” rather than drinking them, and when rats are force-fed to mild obesity, intake of dilute and concentrated saccharin and carbohydrate solutions is progressively reduced.
AppetiteGlucose solution intake in the rat: The specificity of postingestive satiety
26 Citations1983Douglas G. Mook, Julie Ann Brane +2 more
"Satiety" for a glucose solution does not reflect a generalized suppression of hunger or of a specific carbohydrate hunger, but its properties are more specific than existing theories of energy intake regulation would lead us to suppose.

The phenomena observed when animals are offered various sapid materials are impressive to one accustomed to think of animals as “finely tuned regulatory machines”.

It is suggested that it is gustatory adaptation that terminates a saccharin meal in the hungry rat, and that such satiety does not suppress the intake of solid food, of liquid food, or even of a nutritive sweet solution unless it is very dilute.

It is shown that a milk-based liquid diet can also reinstate ingestion in the solution-sated rat, and such a rat increases its intake further when the diet is diluted with water.
