The new sensors will be tested to measure the brain areas stimulated with deep brain stimulation e.g. for Parkinson’s disease. As the stimulated field is responsible for effects and side effects of the stimulation, this will enable the clinician to meet the individual needs of the specific symptom profile. The work packages will include the development of optimal sensor locations, algorithms to locate the stimulated electrode and complex feed-forward solutions for the stimulated area. The project will combine the development of recording and analysis techniques and clinical projects.
