TLDR
Recording made using a single optically‐pumped magnetometer (OPM) in combination with a 3D‐printed head‐cast designed to accurately locate and orient the sensor relative to brain anatomy highlight the opportunity presented by OPMs to generate uncooled, potentially low‐cost, high SNR MEG systems.About:

TL;DR: The physical basis for the signal equation for OPMs is established and the equations defining the bounds on OPM performance are re-derive, leading to a direct upper bound on the gain change due to cross-talk for a multi-channel OPM system.

TL;DR: A wearable OPM-MEG system with ‘whole-head’ coverage based upon commercially available OPMs is constructed, and signal detection is shown for the authors' device to be highly robust, and via application of source-space modelling, it is shown that, despite having 5 times fewer sensors, the system exhibits comparable performance to an established cryogenic MEG device.

A Review of Issues Related to Data Acquisition and Analysis in EEG/MEG Studies
Aina Puce,Matti Hämäläinen +1 more
TL;DR: Issues in data acquisition and analysis of EEG and MEG data are discussed and the increase in methodological complexity in EEG/MEG is discussed, which is important to gather data that are of high quality and that are as artifact free as possible.

Abnormal neural oscillations and synchrony in schizophrenia
TL;DR: Dysfunctional oscillations may arise owing to anomalies in the brain's rhythm-generating networks of GABA (γ-aminobutyric acid) interneurons and in cortico-cortical connections.
