Noise Reduction and Localization Accuracy in a Mobile Magnetoencephalography System [PDF]
SensorsMagnetoencephalography (MEG) non-invasively provides important information about human brain electrophysiology. The growing use of optically pumped magnetometers (OPM) for MEG, as opposed to fixed arrays of cryogenic sensors, has opened the door for ...

Test-retest reliability of the human connectome: An OPM-MEG study. [PDF]
Imaging Neurosci (Camb), 2023 ABSTRACTMagnetoencephalography with optically pumped magnetometers (OPM-MEG) offers a new way to record electrophysiological brain function, with significant advantages over conventional MEG including adaptability to head shape/size, free movement during scanning, better spatial resolution, increased signal, and no reliance on cryogenics.

New avenues for functional neuroimaging: ultra-high field MRI and OPM-MEG. [PDF]
Psychoradiology, 2021 Abstract Functional brain imaging technology has developed rapidly in recent years. On the one hand, high-field 7-Tesla magnetic resonance imaging (MRI) has excelled the limited spatial resolution of 3-Tesla MRI, allowing us to enter a new world of mesoscopic imaging from the macroscopic imaging of human brain functions.

IET Communications, EarlyView., 2022 Abstract The goal of this work is to investigate how the self‐awareness characteristic of autonomic computing, paired with existing performance optimization rules, may be used in applications to minimise multi‐core processor performance concerns. The suggested self‐awareness technique can assist applications in self‐execution while also assisting other

Non-Invasive Functional-Brain-Imaging with an OPM-based Magnetoencephalography System.
PLoS ONE, 2020 A non-invasive functional-brain-imaging system based on optically-pumped-magnetometers (OPM) is presented. The OPM-based magnetoencephalography (MEG) system features 20 OPM channels conforming to the subject's scalp. We have conducted two MEG experiments
