Our main interest is structural plasticity in relation to stress and disease. In addition to apoptosis, we focus on the regulation of adult neurogenesis and its relevance for cognition, depression and dementia. Neurogenesis is prominent particularly during early development, and our primary focus is effects of early stress on (development of) the hippocampus. This brain structure is very sensitive to stress hormone action, implicated in learning and memory and affected in both these disease conditions. The hippocampus is furthermore unique as it contains stem cells that continue to generate new neurons in adult animals, including humans, a process called "adult neurogenesis".
Key interest is the functional relevance of adult neurogenesis for brain function. We are interested in whether blockade or normalization of stress effects on neurogenesis in adult life can be beneficial in terms of e.g. recovery from depression. We hypothesize that e.g. stress-inducedreductions in the number of newborn neurons is deterined during early development and will interfere with the role of the hippocampus e.g. in cognition and in negative feedback of the HPA-axis in adult life. We further study how such deficits can be influenced and possibly ameliorated by means of early diet, antidepressant treatment, or physical or cognitively challenging events such as life long learning and exercise.
