Beyond sensitivity: what are the enabling opportunities of OPM-MEG? [PDF]

Frontiers in Medical Technology
While optically-pumped magnetometer (OPM) technology offers a number of compelling advantages over its SQUID predecessor for magnetoencephalography (MEG), many studies and viewpoints focus on issues of (i) scalp placement, with commensurate increases in ...

Multi-channel whole-head OPM-MEG: Helmet design and a comparison with a conventional system [PDF]

NeuroImage, 2020
Magnetoencephalography (MEG) is a powerful technique for functional neuroimaging, offering a non-invasive window on brain electrophysiology. MEG systems have traditionally been based on cryogenic sensors which detect the small extracranial magnetic ...

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).

A fully integrated whole-head helium OPM MEG: a performance assessment compared to cryogenic MEG [PDF]

Frontiers in Medical Technology
Magnetoencephalography (MEG) is a neuroimaging technique that measures neuronal activity at a millisecond scale. A few years ago, a new generation of MEG sensors emerged: optically pumped magnetometers (OPMs). The most common OPMs use alkali atoms as the

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.
