Socially acquired nicotine i.v. self-administration in adolescent rats
Menthol as a conditioned reinforcer of nicotine reward
Menthol is the most common flavoring additive in tobacco and electronic cigarettes. Using licking as the operant behavior, we found that adolescent rats self-administering nicotine with contingent oral menthol obtained significantly more infusions than rats receiving a vehicle cue or rats self-administering i.v. saline with a menthol cue. Rats yoked to their menthol-nicotine masters emitted significantly fewer licks on the active spouts, indicating that contingent pairing between nicotine and menthol is required for sustained nicotine intake. These results provide a key behavioral mechanism by which menthol promotes the use of tobacco products or electronic cigarettes.
Genetic mapping of nicotine intake in rats
Oral oxycodone self-administration in rats
Pharmacokinetic factors are important contributors to the abuse liability of drugs. Oxycodone is the leading abused prescription drug, despite mostly being mostly taken orally. We are developing an oral oxycodone self-administration model in rats to study the genetic and neuronal mechanisms contributing to its addiction.
