Wearable OPM‐MEG: A changing landscape for epilepsy [PDF]
Epilepsia, 2022 AbstractMagnetoencephalography with optically pumped magnometers (OPM‐MEG) is an emerging and novel, cost‐effective wearable system that can simultaneously record neuronal activity with high temporal resolution ("when" neuronal activity occurs) and spatial resolution ("where" neuronal activity occurs).

Magnetoencephalography with optically pumped magnetometers (OPM-MEG): the next generation of functional neuroimaging [PDF]
Trends in Neurosciences, 2022 Magnetoencephalography (MEG) measures human brain function via assessment of the magnetic fields generated by electrical activity in neurons. Despite providing high-quality spatiotemporal maps of electrophysiological activity, current MEG instrumentation is limited by cumbersome field sensing technologies, resulting in major barriers to utility.
