Research topics :
The team brings together neurosurgeons, neurologists, psychologists, neuropsychologists, researchers and teacher-researchers working in the field of translational therapeutic innovation in functional neurosurgery, for the treatment of neurodegenerative diseases (Parkinson’s disease, Alzheimer’s disease), psychiatric diseases (Obsessive Compulsive Disorders and drug-resistant depressions) and brain tumors. Several lines of research are emerging: a line of neuromodulation of function to restore damaged function, a line of preservation of function during neurosurgical interventions by innovative perioperative brain mapping, a line of research on invasive biomarkers, on tools for detection of Beta particles in tumor exeresis as well as in biotherapies including cell therapy and gene therapy.
Neuromodulation of the injured function is done in the team by biotherapies such as dopamine-restoring enzyme gene therapy or cell therapy or optogenetics, as well as by deep electrical brain stimulation or vagus nerve stimulation. In a translational research approach, the team uses a variety of animal models, ranging from rodents to non-human primates and including ovines.
The concern for preservation of function during neurosurgical interventions led to the collaborative creation of the concept of awake and sleeping surgery based on innovative functional neuroimaging, lesional-mapping and magnetic brain stimulation techniques.
