MEG Sensor Selection for Neural Speech Decoding

IEEE Access, 2020
Direct decoding of speech from the brain is a faster alternative to current electroencephalography (EEG) speller-based brain-computer interfaces (BCI) in providing communication assistance to locked-in patients.

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 ...

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.

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 ...

A Review of Key Technologies in Gravity Matching Navigation

Sensors
The passive nature of gravity matching navigation, along with its concealment and freedom from error accumulation over time, is essential for reducing inertial navigation system (INS) errors and enabling high-precision autonomous underwater positioning ...

Selective Modulation of Evidence Accumulation by Hippocampal Theta Oscillations During Mnemonic Decision‐Making

Human Brain Mapping, Volume 47, Issue 7, May 2026.
Hippocampal theta power during memory retrieval predicts evidence accumulation in a mnemonic similarity task. Trial‐level MEG signals were integrated with a linear ballistic accumulator model, revealing that theta oscillations modulate decision dynamics, linking neural variability to memory‐based discrimination performance.

MEG Evidence of Concurrent Bilateral and Hemisphere‐Specific Developmental Patterns in Auditory Cortex

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Children demonstrate remarkably different temporal characteristics, as well as higher interindividual variability, in the cortical auditory responses as compared with adults. The detailed dynamics at the level of underlying current generators are, however, not established.
