Pediatric magnetoencephalography

Annals of the Child Neurology Society, 2023
Magnetoencephalography (MEG) is a technology used in pediatric and adult epilepsy that records magnetic fields produced from electric currents in the brain. MEG can locate epileptogenic zone(s), lateralize language functions, localize sensorimotor cortex,

Magnetoencephalography: Basic principles

Annals of Indian Academy of Neurology, 2014
Magnetoencephalography (MEG) is the measurement of the magnetic field generated by the electrical activity of neurons. It is usually combined with a magnetic resonance imaging to get what is called magnetic source imaging.

MEG-BIDS, the brain imaging data structure extended to magnetoencephalography [PDF]

Scientific Data, 2018
Abstract We present a significant extension of the Brain Imaging Data Structure (BIDS) to support the specific aspects of magnetoencephalography (MEG) data. MEG measures brain activity with millisecond temporal resolution and unique source imaging capabilities.

Muscle Fatigue Revisited – Insights From Optically Pumped Magnetometers

Frontiers in Physiology, 2021
So far, surface electromyography (sEMG) has been the method of choice to detect and evaluate muscle fatigue. However, recent advancements in non-cryogenic quantum sensors, such as optically pumped magnetometers (OPMs), enable interesting possibilities to

Motor-related oscillatory activity in schizophrenia according to phase of illness and clinical symptom severity

NeuroImage: Clinical, 2021
Magnetoencephalography (MEG) measures magnetic fields generated by synchronised neural current flow and provides direct inference on brain electrophysiology and connectivity, with high spatial and temporal resolution.

Resting-State Neurophysiological Abnormalities in Posttraumatic Stress Disorder: A Magnetoencephalography Study

Frontiers in Human Neuroscience, 2017
Posttraumatic stress disorder (PTSD) is a debilitating psychiatric condition that is common in veterans returning from combat operations. While the symptoms of PTSD have been extensively characterized, the neural mechanisms that underlie PTSD are only ...

Magnetoencephalography-identified preictal spiking correlates to preictal spiking on stereotactic EEG

Epilepsy & Behavior Reports, 2022
Magnetoencephalography (MEG) is a noninvasive diagnostic modality that directly measures neuronal signaling by recording the magnetic field created from dendritic, intracellular, electrical currents of the neuron at the surface of the head.

Magnetoencephalography (MEG) predicts focal epileptogenicity in cavernomas [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2004
The aim of this study was to identify the irritative epileptic zone in patients with cavernomas by means of magnetoencephalography (MEG).Among 82 patients operated for epilepsy, whose presurgical evaluation had included MEG, histological assessment of the tissue removed had confirmed cavernomas in eight. These eight patients had epilepsy since 18.6 (SD
