Scientific Focus

The research focus of the Computational Neuroscience Group at the Goethe-Center for Scientific Computing (G-CSC) is to understand basic neuronal functioning in the brain by applying advanced mathematical and computational methodology in the neuroscientific field. We develop computational methods, models and software for cellular and sub-cellular signal processing in nerve cells, e.g. signal processing in axons and calcium coding in the nucleus, based on theories from continuum mechanics.

We focus on detailed modeling of signal processing in neurons and small networks. We understand the word “detailed” as resolving three-dimensional morphology of the underlying neuronal organelle and modeling the underlying biophysics in a spatio-temporal fashion. In particular we are interested in signal processing on different scales and motivated to couple these with advanced mathematical and computational methods.
