Studying stress-induced structural and functional alterations in animal models for neuropsychiatric disorders

The physiological stress response is essential for our daily survival and helps us to adapt to the ever changing environment. However, sustained uncontrollable stress can induce various dysfunctions and pathological alterations in our body. Our key interest is the structural plasticity of the brain in relation to stress.

We focus on stress-induced changes in neuronal plasticity affecting neuronal networks, adult neurogenesis as well as glial changes in the hippocampus and neocortex. We hypothesize that such stress-induced structural changes contribute to the pathophysiology of psychiatric disorders like depression or schizophrenia, but medications like antidepressant, antipsychotic treatment can also have influence. 

We aim for translational research using multidisciplinary methods ranging from molecular biology to in vitro and in vivo imaging.
