TL;DR: This paper describes a means to characterize resting state brain networks independently using magnetoencephalography (MEG), a neuroimaging modality that bypasses the hemodynamic response and measures the magnetic fields associated with electrophysiological brain activity, and results in RSNs with significant similarity in their spatial structure compared with R SNs derived independently using fMRI.

TL;DR: MRS provides evidence that excitatory tDCS causes locally reduced GABA while inhibitory stimulation causes reduced glutamatergic neuronal activity with a highly correlated reduction in GABA, presumably due to the close biochemical relationship between the two neurotransmitters.

TL;DR: The results extend those from previous studies and add weight to the argument that neural oscillations are intimately related to functional connectivity and the BOLD response and allow the potential to move beyond what is possible using fcMRI, and investigate the nature of electrodynamic connectivity.

TL;DR: 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.
