Research Interests
- Investigation of the neural pathways implicated in drug-seeking behaviour and additionally, the association between mood disorders, stress and drug-seeking behaviour.
- Investigation of molecular mediators of drug-seeking behaviour / drug-induced plasticity.
Laboratory Techniques
- Operant self-administration of alcohol, cocaine and opiates in rats and mice.
- Behavioural sensitization to drugs of abuse.
- Conditioned place preference to drugs of abuse.
- Assessment of affective and cognitive behaviour following acute or chronic treatment with drugs of abuse.
- Quantitative gene and protein expression / neurochemistry.
- Neuropharmacological interventions to regulate drug-seeking.
- Functional neuroanatomy / examining circuitry related to drug-seeking.
- Conditional transgenics.
Additional Information
- Our laboratory uses both rats and mice as experimental models. The latter approach enables us to probe the role of specific genes in drug-seeking and / or drug-induced plasticity.
