Relative intake of saccharin drinking schedule

Centrally administered opioid peptides stimulate saccharin intake in nondeprived rats.

Endogenous opioid peptides are thought to play a role in mediating the pleasurable or rewarding aspects of the ingestion of certain foods and liquids. We therefore measured the effects of central administration of selective opioid agonists and naloxone on the intake of two concentrations of saccharin solution. All tests were performed on nondeprived rats, such that the taste of the solutions pr...

The relationship between saccharin and alcohol intake in rats.

Male rats were given daily sessions during which a palatable saccharin solution was available. Based on intakes averaged over 3 days, groups with low, intermediate, or high intake of saccharin were formed. These rats were then given daily sessions in which alcohol (2-8%) or water were available. Initially, sessions were conducted with rats on a food restriction schedule; in later sessions, food...

Nitrate Intake from Drinking Water in Isfahan in 2004

Development of alcohol deprivation effect in rats: lack of correlation with saccharin drinking and locomotor activity.

The present study addressed the relationship between the parameters of saccharin drinking behaviour and locomotor activity in an open field environment and long-term alcohol self-administration. In a 22-day initiation phase, male Wistar rats were presented with increasing concentrations of ethanol (2-8%, v/v) in a choice with water. The rats were then given the choice between water and two etha...

Running and drinking by rats outside the schedule session.

Two experiments measured the effects of a contingency schedule relating running and eating on the behavior of rats during an "experimental hour" and during two hours before and afterwards. The behaviors recorded during the surrounding hours were drinking and perching (Experiment 1) and running, drinking and perching (Experiment 2). The temporal pattern of drinking in both experiments was unaffe...
