Brief description of research activities

The Laboratory of Neuropsychiatry investigates the biological mechanism underlying psychiatric disorders and circadian rhythms. Research in the laboratory focuses on drug and alcohol abuse, psychosis (with special emphasis on the interaction between the muscarinic and the dopaminergic transmitter systems), affective disorders (including seasonal affective disorder), the effects of stress and electroconvulsive therapy on the brain, and circadian rhythms (with special emphasis on CNS clock genes, the circadian expression of these genes, and the regulation and generation of these rhythms).


muscarinic receptors, drug addiction, depression, schizophrenia, animal models, stress, glucagon-like peptide 1 receptor, neuroplasticity, oxidative stress

Research tools and techniques

behavioral assesment of rodents, microdialysis, immunohistochemistry, insituhybridization, stereology
