Popis: Rats were given 21 days of chronic oral caffeine. A novel flavor (Maintenance CS) was then paired with the continuation of caffeine, and a second flavor (Withdrawal CS) was paired with caffeine removal. Rats avoided the Withdrawal CS, and drank more of the Maintenance CS in a two-bottle test, suggesting that removing caffeine had induced withdrawal. The value of the Maintenance CS was investigated by comparing it to a novel flavor paired with water (Neutral CS). In a series of two-bottle tests, the Maintenance and Neutral CSs were equivalent when pitted against each other, and both were preferred to the Withdrawal CS. These results demonstrate that conditioned flavor avoidance is a useful procedure in assessing caffeine withdrawal, and by inference dependence, produced by chronic oral consumption.
