Description of Research Expertise

RESEARCH INTERESTS
(1) Behavioral pharmacology; (2) Mechanism of action of antidepressant and antianxiety medications; (3) Stress neurobiology and psychiatric disorders

KEY WORDS:
Antidepressants; tranquilizers; stress; serotonin; microdialysis; knockouts; behavior

RESEARCH TECHNIQUES
Behavioral pharmacology in rats and mice; microdialysis measurement of extracellular concentrations of monoamines in conscious rats and mice; behavioral analysis of knockout mice; stereotaxic surgery; effects of brain lesions and neurotoxins on behavior; central drug administration; in vitro ligand binding; histology; radioimmunoassay; and HPLC analysis of brain monoamines

RESEARCH SUMMARY
Current studies focus on the role of specific neurotransmitters, such as serotonin (5-HT), in the behavioral effects of antidepressant and anxiolytic drugs. Animal models for depression and anxiety are used to evaluate the potential efficacy of different neurotransmitter and peptide receptors for clinical therapeutic effects, to identify brain regions associated with behavioral responses to drugs, and to construct and evaluate pharmacological models for improving the efficacy of psychiatric medications. The participation of central 5-HT neurotransmission in depression, anxiety and neuroendocrine regulation associated with behavioral stress is specifically being investigated. Microdialysis procedures are used to measure the release of neurotransmitters in discrete regions of awake freely-moving rats or mice. These studies provide information on the regulation of the release of neurotransmitters in different brain regions, determine environmental and behavioral conditions that alter the release of neurotransmitters, and measure the effects of drugs during behavioral performance. Finally, studies of different inbred mouse strains or knockout mice are examining genetic factors associated with complex behaviors and the behavioral effects of psychotherapeutic medications.

Description of Itmat Expertise

Dr. Lucki's specializes in behavioral pharmacology and measuring the effects of drugs on behavior with particular attention to the effects of stress and disease, psychopharmacology of antidepressant and anxiolytic medications.
