This study demonstrates that on-scalp MEG using optically-pumped magnetometers can robustly detect human visual gamma-band responses with improved spatial resolution compared to conventional SQUID-based MEG.

This paper develops and validates a co-registration method for on-scalp MEG systems, improving accuracy and ease of use compared to traditional methods.

This paper describes an on-scalp MEG system using optically-pumped magnetometers with external compensation coils to reduce ambient magnetic fields and improve sensor performance.

This study quantifies the requirements for sensor coregistration accuracy in on-scalp MEG systems using simulations, finding that position errors have a larger impact than orientation errors.

This study compares the performance of on-scalp OPM arrays with a standard SQUID array in MEG, finding higher signal power and information capacity in OPMs.
