Towards a New Generation of Magnetoencephalographs: Evaluation of the FYNA Research (Mag4Health 48 Sensors MEG's Name) System Full-head Magnetoencephalographs System With Optically Pumped Magnetometers

What this Trial Is About

Researchers are evaluating a new generation of magnetoencephalography (MEG) devices that use optically pumped magnetometers with Helium 4 to record brain magnetic activities. The study includes healthy adults and male athletes who have suffered a mild concussion. The goal is to compare this new device's ability to detect and map brain activity with that of classical MEG systems, focusing on brain responses to visual, auditory, somatosensory, and motor stimuli. Participants will undergo several experiments using the FYNA Research MEG system. Healthy volunteers will complete tasks involving visual and auditory attention, language production, rest, and visuo-motor activities. Concussed athletes will have their resting brain activity recorded to assess frequency modulations. The study compares signal-to-noise ratios and brain activity maps from the new device with those from classical MEG during these tasks. During the study, participants will visit once for inclusion and then return within 1 to 30 days for MEG recordings and assessments. Researchers will measure signal quality, brain activity mapping, and participant comfort through questionnaires after recording sessions. The study monitors safety and participant experience, aiming to gather detailed data on the new MEG device's performance. Total participation time depends on scheduling within the defined visit window.
