Helium 4 Optically Pumped Magnetometers : a New Generation of Sensors for High Speed Functional Brain Imaging
Helium 4 Optically Pumped Magnetometers : a New Generation of Sensors for High Speed Functional Brain Imaging
Our goal is to perform a first evaluation of the capabilities of a new generation of non-invasive magnetoencephalography sensors (OPM He4) to record brain magnetic activities. The investigator will record 1) normal subjects stimulated with visual, auditory, somesthesic and motor stimuli and 2) epileptic patient. The investigator will compare the signal to noise ratio of the normal or pathological activities between classical MEG sensors and our OPM He4 prototype.
