A core aspect of our research is to relate animal to human learning, and to link learning to neural circuit function. Eventually, our goal is to translate mechanistic insights from basic research to the clinics. We want to improve developmental delay diagnosis and to design innovative treatment strategies.
Animal models are indispensable for dissecting circuit functions, but learning and cognitive capabilities differ between humans and animals. Thus, it is not straightforward to directly map animal behavior and circuit mechanisms onto human brain function and behavior. However, identifying shared learning-related processes across species and revealing their common characteristics is a great asset. We are developing tasks and computational models that can be conducted in parallel in mice, healthy humans, and patients. We use them to investigate multi-sensory learning, an important cognitive function that may be fundamentally disrupted in developmental disorders. Use of the same tasks and models in these parallel investigations makes it possible to detect the neural circuit mechanisms underlying behavioral deficits in patients and to study them at the circuit and molecular level in animals.
The ultimate goal is to translate new mechanistic insights about neural circuit function gained through coordinated animal and human research into the clinics by developing improved diagnostic tools and treatment strategies. Surprisingly, sensory and multi-sensory behaviors that require integrative circuit functions are typically not assessed during developmental delay diagnosis, even though they likely are disrupted in such patients and may even represent core symptoms. We thus plan to incorporate our new standardized multi-sensory behavioral assay into the standard test battery for developmental delay diagnosis. Further, the identification of the molecular and genetic mechanisms of impaired neural circuit development would help to counsel parents and health care professionals by predicting developmental trajectories and facilitate tailored therapeutic interventions.
In this project, we developed tasks to assess multi-sensory learning in humans and combined
them with fMRI measurements in healthy adults. We want to identify brain areas involved in learning of multi-sensory associations.

In an interventional study, we aim to develop a support program and to evaluate its effectiveness regarding math performance and neuronal changes in the brain of adolescents and adults with dyscalculia.
We are looking for participants with dyscalculia (see flyer (PDF, 249 KB), in German) and without dyscalculia (see flyer (PDF, 601 KB), in German).
