Laboratory of Genetic Neuropharmacology

The Laboratory of Genetic Neuropharmacology (LGN) is interested in studying the functions of GABAA receptor subtypes in the central nervous system using genetically modified mice, which allow us to modulate expression of GABAA receptor subunits in defined neuronal circuits.  We are interested in the role of GABAA receptors in emotional regulation (anxiety, depression), learning and memory, drug abuse, and for the amnestic action of general anesthetics.
In addition, in a separate line of research, we are working on etiological models of schizophrenia, i.e. genetically modified mice which harbor structural genomic variations associated with psychosis.
