Overview of MEG [PDF]

open access: yesOrganizational Research Methods, 2016
Magnetoencephalography (MEG) is a method to study electrical activity in the human brain by recording the neuromagnetic field outside the head. MEG, like electroencephalography (EEG), provides an excellent, millisecond-scale time resolution, and allows the estimation of the spatial distribution of the underlying activity, in favorable cases with a ...

Quasi-Movements and “Quasi-Quasi-Movements”: Does Residual Muscle Activation Matter?

open access: yesLife, 2023
Quasi-movements (QM) are observed when an individual minimizes a movement to an extent that no related muscle activation is detected. Likewise to imaginary movements (IM) and overt movements, QMs are accompanied by the event-related desynchronization ...

Evolution of MEG : A first MEG ‐feasible fluxgate magnetometer [PDF]

open access: yesHuman Brain Mapping, 2021
Abstract In the current article, we present the first solid‐state sensor feasible for magnetoencephalography (MEG) that works at room temperature. The sensor is a fluxgate magnetometer based on yttrium‐iron garnet films (YIGM). In this feasibility study, we prove the concept of usage of the YIGM in terms of MEG by registering a simple

Effects of the antibiotic rifaximin on cortical functional connectivity are mediated through insular cortex

open access: yesScientific Reports, 2021
It is well-known that antibiotics affect commensal gut bacteria; however, only recently evidence accumulated that gut microbiota (GM) can influence the central nervous system functions.

Cortical magnetic activation following voluntary movement and several types of somatosensory stimulation

open access: yesJournal of Physical Fitness and Sports Medicine, 2016
Magnetoencephalography is primarily sensitive to current sources tangential to the skull. Therefore, currents generated in area 3b of the primary somatosensory cortex (S1) and area 4 of primary motor cortex (M1) located on the posterior and anterior ...

Visual gamma oscillations predict sensory sensitivity in females as they do in males

open access: yesScientific Reports, 2021
Gamma oscillations are driven by local cortical excitatory (E)–inhibitory (I) loops and may help to characterize neural processing involving excitatory-inhibitory interactions.

Bacteriophages limitedly contribute to the antimicrobial resistome of microbial communities in wastewater treatment plants

open access: yesMicrobiology Spectrum, 2023
Bacteriophages are known as players in the transmission of antimicrobial resistance genes (ARGs) by horizontal gene transfer. In this study, we characterized the bacteriophage community and the associated ARGs to estimate the potential for phages to ...

Losses resulting from deliberate exploration trigger beta oscillations in frontal cortex

open access: yesFrontiers in Neuroscience, 2023
We examined the neural signature of directed exploration by contrasting MEG beta (16–30 Hz) power changes between disadvantageous and advantageous choices in the two-choice probabilistic reward task.

MEG-PLAN: a clinical and technical protocol for obtaining magnetoencephalography data in minimally verbal or nonverbal children who have autism spectrum disorder

open access: yesJournal of Neurodevelopmental Disorders, 2021
Background Neuroimaging research on individuals who have autism spectrum disorder (ASD) has historically been limited primarily to those with age-appropriate cognitive and language performance. Children with limited abilities are frequently excluded from

Cross-Axis Dynamic Field Compensation of Optically Pumped Magnetometer Arrays for MEG

open access: yesNeuroImage, 2022
We present dynamic field compensation (DFC), whereby three-axis field measurements from reference magnetometers are used to dynamically maintain null at the alkali vapor cells of an array of primary sensors that are proximal to a subject's scalp ...
