Our research focuses on the electrophysiology of movement disorders, such as Parkinson’s disease or essential tremor. We are particularly interested in the relationship between brain activity on the one hand and symptoms, such as tremor or cognitive impairments, on the other hand. Is it possible to tell from brain recordings which symptoms are currently present and how they will respond to therapy? Is it possible to derive recommendations for clinicians, e.g. on the best configuration of a deep brain stimulation system? Can electrophysiological recordings help us find the correct diagnosis? To answer these and similar questions, we record brain activity in patients and look for patterns related to specific symptoms using advanced data analysis methods, and machine learning in particular. Magnetoencephalography (MEG) is our primary tool for measuring brain activity.
