Cortical locations of maximal spindle activity: magnetoencephalography (MEG) study [PDF]

Journal of Sleep Research, 2009
SummaryThe aim of this study was to determine the main cortical regions related to maximal spindle activity of sleep stage 2 in healthy individual subjects during a brief morning nap using magnetoencephalography (MEG). Eight volunteers (mean age: 26.1 ± 8.7, six women) all right handed, free of any medical psychiatric or sleep disorders were studied ...

Performance Analysis of Optically Pumped ⁴He Magnetometers vs. Conventional SQUIDs: From Adult to Infant Head Models

Sensors, 2022
Optically pumped magnetometers (OPMs) are new, room-temperature alternatives to superconducting quantum interference devices (SQUIDs) for measuring the brain’s magnetic fields.

Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.

Structural Eigenmodes of the Brain to Improve the Source Localization of EEG: Application to Epileptiform Activity

Advanced Science, EarlyView.
Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

Virtual localization of the seizure onset zone: Using non-invasive MEG virtual electrodes at stereo-EEG electrode locations in refractory epilepsy patients

NeuroImage: Clinical, 2018
In some patients with medically refractory epilepsy, EEG with intracerebrally placed electrodes (stereo-electroencephalography, SEEG) is needed to locate the seizure onset zone (SOZ) for successful epilepsy surgery.

A magnetoencephalography dataset during three-dimensional reaching movements for brain-computer interfaces

Scientific Data, 2023
Studying the motor-control mechanisms of the brain is critical in academia and also has practical implications because techniques such as brain-computer interfaces (BCIs) can be developed based on brain mechanisms.

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.

Structural and Functional Imaging of Motor Outcomes in Twins With Perinatal Stroke: A Case Report

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Perinatal arterial ischemic stroke (AIS) affects 1 in 4000 live births. Dystonia, affecting ~20% of children following AIS, is characterized by involuntary muscle contractions and abnormal movements. Why some develop dystonia post AIS, while others do not, remains unclear.

The usefulness of intraoperative electrocorticography (iECoG) in pediatric temporal lobe epilepsy surgery

Epileptic Disorders, EarlyView.
Abstract Objective This study aimed to evaluate the usefulness of intraoperative electrocorticography (iECoG) in providing a more accurate surgical strategy, thereby yielding seizure freedom following resective surgery in children with temporal lobe epilepsy (TLE).

Magnetoencephalography in stroke recovery and rehabilitation

Frontiers in Neurology, 2016
Magnetoencephalography (MEG) is a non-invasive neurophysiological technique used to study the cerebral cortex. Currently, MEG is mainly used clinically to localize epileptic foci and eloquent brain areas in order to avoid damage during neurosurgery.
