Condition: Mild Concussion · Healthy Volunteers · Sponsor: Hospices Civils de Lyon
The goal is to perform a first evaluation of the capabilities of a new generation of non-invasive magnetoencephalography whole head device using optically pumped magnetometers using Helium 4 as the sensitive element (OPM He4) to record brain magnetic activities. The investigators will record 1) healthy subjects stimulated with visual, auditory, somesthesic and motor stimuli and 2) athletes who suffered a mild concussion. The main hypothesis is that the OPM magnetoencephalographs (MEG) system will be able to detect brain activity. The secondary hypothesis is that the data recorded with the OPM MEG system will allow to reconstruct maps of the brain activity. To test the main hypothesis, they will compare the signal to noise ratio of brain activities between a classical MEG system and the new OPM He4 MEG. The secondary hypothesis will be tested through a comparison of the maps of brain activity obtained thanks to the data recorded with a classical MEG system and the new OPM He4 MEG.
