Current Research

“Dopamine (DA) is a catecholamine neurotransmitter found in the mammalian brain and regulates many critical physiological processes such as movement, cognition, motivation, reward/pleasure, and hormone regulation. Dysfunction of the dopamine system has been implicated in many brain disorders, including Parkinson’s disease (PD), schizophrenia, OCD, and ADHD. The goal of the Urs Lab is to study the role of genetic and environmental factors on dopamine neurotransmission and to learn more about the dopamine system by deciphering, a) signaling pathways involved in DA neurotransmission, b) functional dopamine neuronal circuits, and c) how these integrate and manifest behaviorally in an organism (mouse). Using these integrated approaches—in parallel—will allow us to fine-tune dopamine neurotransmission and devise novel drug- and gene-based therapeutic approaches to treat dopamine-related disorders such as PD and schizophrenia.” (Department Webpage)
