Abstract

A recent paper by Boto et al. established reliability of noninvasive functional connectivity measurements with a new whole-head optically pumped magnetometer magnetoencephalography (OPM-MEG) system. This rapidly developing technology enables a conformal sensor array to accommodate different head sizes and opens up new avenues for experiments in more naturalistic settings.

Keywords: on-scalp MEG; resting-state networks; task-based connectivity.
