Learned taste aversion to saccharin produced by orally consumed d-amphetamine
Pharmacology, Biochemistry, and Behavior
|July 1, 1980
Summary
Rats developed taste aversions to saccharin solutions when combined with d-amphetamine. The generalization of this aversion to different saccharin concentrations depended on the initial conditioning concentration.
Area of Science:
- Neuroscience
- Behavioral Psychology
- Pharmacology
Background:
- Taste aversion learning is a crucial survival mechanism.
- Drug-induced taste aversions can provide insights into drug effects and learning processes.
Purpose of the Study:
- To investigate the development and generalization of taste aversions in rats when saccharin solutions are paired with d-amphetamine.
- To determine how conditioning concentration affects the generalization of taste aversions.
Main Methods:
- Rats were exposed to solutions containing saccharin and d-amphetamine.
- Taste aversion development and generalization to varying saccharin concentrations were assessed.
- The effect of conditioning concentration on aversion generalization was examined.
Main Results:
- Taste aversions were successfully conditioned to saccharin solutions containing d-amphetamine.
- Aversion generalization to lower saccharin concentrations varied based on the conditioning concentration.
- Conditioning with lower saccharin concentrations led to broader generalization.
Conclusions:
- Oral d-amphetamine can effectively condition taste aversions in rats.
- The concentration of saccharin used during conditioning significantly influences the generalization of taste aversions.
- Findings suggest similarities between taste aversions conditioned with oral and injected d-amphetamine.
