Research group description

The reserach group working in neurostimulation uses non-invasive, transcranial brain stimulation techniques (TMS, TDCS, TACS) in combination with electrophysiological (EEG/MEG) and imaging (fMRI) methods to investigate the function of neuronal oscillations in the regulation of information processing and neuronal plasticity. In the future, we want to use this to better understand the neural basis of resilience and identify those neural networks and oscillations that mediate and regulate the encoding, consolidation, and reorganization (while awake and asleep) as well as the retrieval of emotional (or traumatic) memory content. The methodological focus of the group is on the simultaneous application of multi-modal measurement and stimulation methods (e.g., EEG-fMRI, TMS-EEG, TMS-fMRI) and the development of neurostimulation dependent on the brain state in real time (e.g., real-time EEG-triggered TMS).
