Lehnertz Workgroup - Neurophysics

Our goal is to develop new diagnosis-, treatment- and intervention options for patients with epilepsy and other neurological diseases. In order to do so, we analyse and model complex dynamics of the human brain with different temporal- and spatial-scales with the goal of improving our understanding of normal brain function and the epileptic processes, in particular the genesis, spreading, and cessation of seizures. We also aim to improve existing methods while developing new methods and times series analysis procedures from statistical physics, dynamic systems theory, synchronisation, and network theory and model multi-scale neuronal dynamics on complex networks.  For numeric analyses and simulations, a 200 node computer cluster is available.
