Dorsal Root Ganglion Stimulation Modulates Cortical Gamma Activity in the Cognitive Dimension of Chronic Pain

open access: yesBrain Sciences, 2020
A cognitive task, the n-back task, was used to interrogate the cognitive dimension of pain in patients with implanted dorsal root ganglion stimulators (DRGS).

Simultaneous whole-head electrophysiological recordings using EEG and OPM-MEG

open access: yesImaging Neuroscience, 2023
Electroencephalography (EEG) and magnetoencephalography (MEG) non-invasively measure human brain electrophysiology. They differ in nature; MEG offers better performance while EEG (a wearable platform) is more practical.

Maturational trajectory of fusiform gyrus neural activity when viewing faces: From 4 months to 4 years old

open access: yesFrontiers in Human Neuroscience, 2022
Infant and young child electrophysiology studies have provided information regarding the maturation of face-encoding neural processes. A limitation of previous research is that very few studies have examined face-encoding processes in children 12–48 ...

Exploring the limits of MEG spatial resolution with multipolar expansions [PDF]

open access: yesNeuroImage, 2022
The advent of scalp magnetoencephalography (MEG) based on optically pumped magnetometers (OPMs) may represent a step change in the field of human electrophysiology.

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

Towards an objective evaluation of EEG/MEG source estimation methods - The linear approach

open access: yesNeuroImage, 2022
The spatial resolution of EEG/MEG source estimates, often described in terms of source leakage in the context of the inverse problem, poses constraints on the inferences that can be drawn from EEG/MEG source estimation results.

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 ...

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.
