Dr. Hurd's multidisciplinary research investigates the neurobiology underlying addiction disorders and related psychiatric illnesses. A translational approach is used to examine molecular and neurochemical events in the human brain and comparable animal models in order to ascertain neurobiological correlates of behavior. A major focus of the research is directed to risk factors of addiction disorders including genetics as well as developmental exposure to drugs of abuse.

The research group investigates the neurobiology underlying drug abuse and related psychiatric disorders. The work is focused on the systematic study of the human brain of drug abusers and subjects with psychiatric disorders in relation to opioid neuropeptide, cannabinoid and dopamine neuronal systems. Drug abuse and, e.g., major depression are associated with alterations of mood, cognition, and motivation, thus, an important goal is to identify and map specific genes in the mesocorticolimbic system, which regulate emotional function. Techniques such as in situ hybridization, RT-PCR, DNA microarray, in vitro autoradiography, and general biochemical assays are used for the detailed analyses of genes, and respective protein products, in discrete mesocorticolimbic brain areas. Molecular, biochemical, and in vivo studies of the human brain are assessed in relation to individual genotype in order to identify neurobiological correlates of functional genetic polymorphisms linked to addiction and affective disorders. Epigeneic mechanisms, e.g., DNA methylation, are also evaluated in relation to the regulation of gene expression.
A significant area of investigation is related to assessing the impact of prenatal drug exposure on human fetal brain development that may enhance later risk for substance abuse and psychiatric disturbances. Recent collaborative efforts involve in vivo imaging of the developing mesocorticolimbic system to examine the neurobiological association between behavioral traits (e.g., inhibitory control deficit) that appear to increase risk for substance abuse disorders.
As complement to studies of the human brain, animal models are used to examine in vivo neurotransmitter levels (e.g., dopamine as measured by the microdialysis technique) in discrete mesocorticolimbic brain areas during, e.g., operant drug self-administration behavior. The animal studies are designed to mimic the prenatal and adolescent drug exposure (particularly cannabis) seen in humans, and subsequent adult behaviors are linked to in vivo neurochemical fluctuations as well as molecular and biochemical events in the same subject.
