From molecules to behavior

We want to discover new molecular mechanisms underlying neural circuit development under physiological conditions. Further, we want to investigate how newly identified pathogenic gene mutations that cause neurodevelopmental phenotypes affect neural circuit formation and function and multi-sensory processing in animal models and humans.

Neural circuit formation relies on well-orchestrated molecular processes to generate neurons and connect them to functional networks. Neurons extend processes that establish precise synaptic connections with target cells. Newly formed networks are shaped by neural activity and sensory experience and establish appropriate, adaptive behavior. Comparing different circuits across several species allows us to identify fundamental molecular pathways and to better understand circuit formation. Further, analysis of patient cohorts with specific deficits, such as intellectual disability, will allow us to identify candidate gene mutations and investigate whether and how they affect neural function or circuit formation.
