Optically pumped magnetometers (OPMs) can be used for magnetoencephalography (MEG) with equivalent or improved signal to noise ratio, relative to cryogenic MEG, when sensors are placed close to the scalp. OPM-based MEG can also be used in mobile contexts if sensors are placed in lightweight, wearable arrays. Individual...

It is shown that the spinal contribution to cortico-muscular coupling manifests as coherent 10-35 Hz activity linking the contralateral sensorimotor cortex, cervical spinal cord, and muscle, which forms a distributed, bidirectionally interacting network with physiologically plausible temporal delays.

A lightweight, low-cost, multichannel magnetoencephalography system that can image brain activity without needing a magnetically shielded room, and it is shown that the signal to noise ratio of the in-vivo recordings is comparable to what can be obtained from a conventional cryogenically-cooled MEG system sited within...
