Non-Invasive Functional-Brain-Imaging with an OPM-based Magnetoencephalography System.

PLoS ONE, 2020
A non-invasive functional-brain-imaging system based on optically-pumped-magnetometers (OPM) is presented. The OPM-based magnetoencephalography (MEG) system features 20 OPM channels conforming to the subject's scalp. We have conducted two MEG experiments
