Summary of Current Research
My laboratory focuses on motivational (rewarding and aversive) effects of abused drugs, with special emphasis on drug-seeking and drug-taking behaviors. Our studies generally involve behaviors that are established through Pavlovian conditioning or instrumental learning procedures (e.g., conditioned place preference/aversion, drug self-administration). In some studies, our goal is to identify and characterize the physiological, neuroanatomical, neurochemical, and molecular systems that mediate drug reward and aversion, including studies that involve systemic or intracranial administration of pharmacological agents (e.g., receptor agonists or antagonists). For example, in one recent project, infusion of a dopamine receptor antagonist into the amygdala (but not nucleus accumbens) reduced expression of ethanol conditioned place preference, suggesting an important role of dopamine receptors within that brain area in ethanol-conditioned reward. In other studies, we are more directly concerned with increasing our knowledge about current models of drug-seeking behavior and developing better models. We have been especially interested in the somewhat paradoxical finding that ethanol produces both positive and negative motivational effects, depending on the behavioral procedure. In another series of studies, we are developing a new model of intragastric alcohol consumption (IGAC) in mice that are tolerant and dependent. Recent studies with the IGAC model have shown that passive exposure to ethanol will substantially increase later voluntary self-infusion of ethanol (relative to water exposed controls), even in mouse strains that normally avoid ethanol in drinking procedures. Finally, several projects focus on genetic influences, with the long-term goal of identifying specific genes that underlie the rewarding and aversive effects of abused drugs. These studies involve various animal genetic models, including selectively bred mouse lines and inbred mouse strains.
