The Marseille MEG platform.

MEG figure1.jpg




Magnetoencephalography (MEG) consists in recording brain magnetic activity. This activity is the counterparts of the electrical activity that originate from the brain, the well-known EEG. These techniques are the only ones that are directly related to the neural activity and have enough time resolution to track brain activity. One of the great advantages of the MEG other EEG is the very small effect of the geometry of the different media of the head, especially the skull, on the signal recorded compared to EEG.

The MEG laboratory of Marseille uses a 248 magnetometers MEG system (4D Neuroimaging magnes 3600), installed within the Neurophysiology department of Timone hospital (Head: F. Bartolomei). The system was co-financed by: Conseil Régional PACA, Conseil Général 13, Conseil Général 06, Marseille Provence Métropole, INSERM, CNRS, INRIA. It is currently co-financed by Aix-Marseille Université (though France Life Imaging) and INSERM.

The laboratory is equipped with stimulation apparatus that includes video projection and Stax calibrated system for auditory stimulation. It belongs to the Aix-Marseille University and is accessible to all teams involved in fundamental and clinical brain research.

The research team of the MEG laboratory is specialized in confronting results of source localization to intracerebral EEG (Dubarry et al 2014, Gavaret et al 2004, Koessler et al 2010), and in designing and optimizing signal processing methods for multimodal functional investigation of human cerebral activity (pathological and physiological) (Jmail et al 2011, Krieg et al 2011).

See Dynamap page.


The AnyWave Software

The MEG laboratory is currently developping a software called Anywave for the visualisation and analysis of electrophysiological data: MEG, EEG, SEEG (developper: Bruno Colombet, with help from M. Woodman, Engineer financed by Fondation pour la recherche medicale).
The guiding principles are modularity and cross-platform portability.
See AnyWave.
