Welcome to the Research Group "Interventional Neurophysiology and Neuropsychology" (interPHYS). We are dedicated to the research of motor, cognitive and emotional functions by means of behavioural experiments and interventional neurophysiology in the context of neuromodulation techniques.Our group is part of the Institute of Clinical Neuroscience and Medical Psychology, University Duesseldorf, Germany. (Chair: Prof. Dr. A. Schnitzler). Our research is furthermore embedded in the Neurological Clinic of the University Hospital Duesseldorf.We electrically or magnetically modulate brain activity (by means of Deep Brain Stimulation or Transcranial Electrical Stimulation or Transcranial Magnetic Stimulation) and examine resulting behavioural outcome. On the other hand, we modulate behaviour with psychological paradigms and examine the resulting neuronal (oscillatory) activity by means of invasive (local field potentials, multi unit) and non-invasive (EEG, MEG) recordings. Our aim is to understand neuronal networks in the context of brain diseases and to develop therapeutic concepts.
