Scientific Focus

Stroke is the leading cause of disability in the western world. In Germany, approximately 200,000 people per year suffer from a stroke, and over 50% of stroke survivors remain disabled by a permanent neurological deficit, despite pharmacological treatment and extensive physiotherapy (https://www.dgn.org).

Our  scientific mission is to further our understanding of stroke-induced disturbances in brain network functions and the development of novel treatment strategies to promote recovery of function.

The aim is to elucidate which brain regions constitute key players in the process of functional reorganization, and how non-invasive brain stimulation may be used to “re-shape” neural networks to promote recovery of function. To achieve this, we combine neuroimaging and computational neuroscience with behavioral, technical or pharmacological interventions that allow us to enhance neural plasticity and neurorehabilitation.

 

Methods

structural/functional MRI, electroencephalography (EEG), transcranial magnetic stimulation (online-TMS, offline rTMS), concurrent TMS-EEG, movement kinematics, machine learning, RCTs
