MEG helmet

For neuroimaging, engineers at the University of Nottingham have designed a helmet with sensors that combine optically-pumped magnetometers (OPMs), and magnetoencephalography (MEG).  “Here, building on previous work, we construct a wearable OPM-MEG system with ‘whole-head’ coverage based upon commercially available OPMs, and test its capabilities to measure alpha, beta and gamma oscillations. We design two methods for OPM mounting; a flexible (EEG-like) cap and rigid (additively-manufactured) helmet.”  MORE
