Project

The goal of the neurophysiology project team is to develop and use the neurophysiological tools (high-resolution electroencephalogram, non-invasive brain stimulation, motion analysis) necessary for the understanding and management of neurologically expressed diseases. More fundamental aspects aiming to better understand brain function and to develop relevant markers of a pathophysiological process are also developed. The team is particularly interested in motor control and its interactions with cognitive impairment, whether in aging (impact on falls) or in pathologies of the basal ganglia (Parkinson's disease), in post-stroke, in dementias, epilepsy or in neuro-muscular diseases. A final approach concerns decisional medicine. The aim is to exploit the physiological markers identified in cohort studies to facilitate their use in routine clinical practice. The work is based on the use of machine learning and big data approaches to build decision models going to the individual patient level and optimally combining the different markers.

 

Team: Nacim Betrouni et Philippe Derambure

Highlights

• Development of numerous collaborations in recent year

• • at the Lille campus (Cristal laboratory, François Cabestaing, development of brain-machine interfaces, Scalab, Cedrick Bonnet, posturographic aspects; Ali Amad and Arnaud Leroy, neuromodulation and behavioral disorders),
  • at the regional level (ULCO, Hervé Devanne: modulation of cortical activity, plasticity and consequences on motor control)
  • at a national level (University of Bordeaux, Prof. Dominique Guehl, Prof. Fabrice Wendling and Mahmoud Hassan (LTSI UMR Inserm Université de Rennes))
  • at an international level (University of Kiel, Christian Schlenstedt, University of Nijmegen, Bas Bloem, Claudio Babiloni (Department of Physiology and Pharmacology, University of Sapienza, Italy)…

• Implementation over the past 3 years of methods for analyzing functional connectivity in EEG
• Development of operational routines within the team to accommodate students with little training in signal processing (source analysis, evoked potentials, time-frequency analysis, connectivity)
• Technical platform allowing communication of tools (stimulation PC allowing administration of cognitive tests, High resolution EEG, movement analysis system, neuromodulation systems, etc.)
