- Dr. Yasmin Hurd is Professor in the Departments of Psychiatry, Neuroscience and Pharmacology and Systems Therapeutics. She is the Director of the Center for Addictive Disorders.
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.

ResearchThe 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, RNA-sequencing, chromatin immunoprecipitation, 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 and histone modifications, are also evaluated in relation to the regulation of gene expression.
A significant area of investigation is related to assessing the impact of early developmental cannabis exposure on the human brain and translational animal models that may enhance later risk for substance abuse and psychiatric disturbances. Recent efforts involve combined in vivo imaging and molecular pharmacogenetic strategies to provide quantitative, dynamic and cell type-specific functional circuit mapping throughout the brain relevant to normal behavior and pathological states underlying neuropsychiatric disorders.
As complement to studies of the human brain, animal models are used to monitor in vivo neurotransmitter levels (e.g., dopamine as measured by the microdialysis technique) and virally manipulate specific genes and epigenetic mechanisms within discrete cell populations in discrete brain areas during behavior such as operant drug self-administration behavior (particularly heroin and cocaine). The animal studies are also designed to mimic the prenatal and adolescent drug exposure (particularly cannabis) seen in humans, and to track the protracted impact on adult behavior and molecular events in the same subject or across generations.
