The TOBergmannLab (AG Neurostimulation) is part of the Leibniz Institute for Resilience Research (LIR). We investigate the function of neuronal oscillations in cognition (in particularly attention and memory), trying to understand their role in defining brain states, organizing information processing, and gating synaptic plasticity in the wake and sleeping human brain, as well as the neuronal mechanisms mediating their top-down control. To answer our research questions, we follow a multimodal approach, combining non-invasive transcranial brain stimulation techniques (TMS, TDCS, TACS) with electrophysiological recordings (EEG, MEG) and neuroimaging (fMRI). The methodological focus of the group lies on the simultaneous application of these techniques (including concurrent EEG-fMRI, TMS-fMRI, TMS-EEG, TCS-MEG, TCS-TMS) as well as brain state dependent brain stimulation approaches, such as real-time EEG-triggered TMS.
