Deficient inhibition of irrelevant visual information in migraine: A magnetoencephalography study of alpha‐band activity

Headache: The Journal of Head and Face Pain, Volume 66, Issue 7, Page 1459-1473, July/August 2026.
Abstract Objectives/Background There is growing evidence that migraine is associated with attentional abnormalities, both during and between attacks, potentially affecting the cognitive processing of sensory stimulation. However, the underlying neurophysiological mechanism remains poorly understood.

A Three‐Dimensional Structural Model for Predicting Magnetic Exchange and Hydrogen Positions in Bis‐μ‐Hydroxido Cu(II) Dimers

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

Sleep magnetoencephalography enhances detection and source imaging of seizures and fast oscillations in focal cortical dysplasia

Epilepsia, Volume 67, Issue 6, Page 2992-3008, June 2026.
Abstract Objective Focal cortical dysplasia (FCD) causes drug‐resistant epilepsy requiring presurgical evaluation. Invasive electroencephalographic (EEG) studies demonstrate that sleep modulates epileptic activity, including interictal epileptiform discharges (IEDs), fast oscillations (FOs) in the beta (14–40 Hz) and gamma (40–80 Hz) frequency bands ...

Full Tensor Eigenvector Analysis on Air-Borne Magnetic Gradiometer Data for the Detection of Dipole-Like Magnetic Sources

Sensors, 2017
The detection of dipole-like sources, such as unexploded ordnances (UXO) and other metallic objects, based on a magnetic gradiometer system, has been increasingly applied in recent years.

Thalamic connectivity mirrors spatial maps of network dysfunction in nonlesional focal epilepsy

Epilepsia, Volume 67, Issue 6, Page 3023-3033, June 2026.
Abstract Objective Focal epilepsy is increasingly conceptualized as a network disorder, yet the extent to which network dysfunction reflects a shared phenotype remains unknown. Spatially conserved patterns of network dysfunction may implicate a centralized mechanism underlying widespread impairment.

Accounting for linear transformations of EEG and MEG data in source analysis.

PLoS ONE, 2015
Analyses of electro- and magnetoencephalography (EEG, MEG) data often involve a linear modification of signals at the sensor level. Examples include re-referencing of the EEG, computation of synthetic gradiometer in MEG, or the removal of artifactual ...

CALIBRATION METHOD FOR GRAVITY GRADIOMETERS BY MEANS OF TWO ROTATING CYLINDERS

Приборы и методы измерений, 2015
The problem of maintaining a constant gravitational gradient in a relatively large volume of space is considered.  This  provides  a  well  defined  input  signal  to  a  gravity  gradiometer  for  the  purpose  of  its calibration.

Modulation of Visual Contrast Perception Associated With Dorsal Attention Network Connectivity Assessed by Magnetoencephalography

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.
Magnetoencephalography was used to identify the impact of spatial attention on primary visual cortical responses to stimuli of varying contrast levels. Enhancement of the maximal response of the visual cortex to high contrast stimuli was associated with synchronous communication between the dorsal attention network and visual cortex within the alpha ...

sBOSC: A Method for Source‐Level Identification of Neural Oscillations in Electromagnetic Brain Signals

Psychophysiology, Volume 63, Issue 6, June 2026.
ABSTRACT Neural oscillations are recognized as a fundamental component of brain electromagnetic activity. They are implicated in a wide range of cognitive processes and proposed as a core mechanism for brain communication. Nonetheless, detecting genuine neural oscillations remains a methodological challenge, particularly due to the difficulty of ...

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, Volume 13, Issue 5, Page 888-898, May 2026.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...
