An inversion method based on random sampling for real-time MEG neuroimaging [PDF]

open access: yes, 2019
The MagnetoEncephaloGraphy (MEG) is a non-invasive neuroimaging technique with a high temporal resolution which can be successfully used in real-time applications, such as brain-computer interface training or neurofeedback rehabilitation.

Magnetoencephalography: Basic principles

open access: yesAnnals of Indian Academy of Neurology, 2014
Magnetoencephalography (MEG) is the measurement of the magnetic field generated by the electrical activity of neurons. It is usually combined with a magnetic resonance imaging to get what is called magnetic source imaging.

OMMR: Co-registration toolbox of OPM-MEG and MRI

open access: yesFrontiers in Neuroscience, 2022
Magnetoencephalography (MEG) based on optically pumped magnetometers (OPM-MEG) has shown better flexibility in sensor configuration compared with the conventional superconducting quantum interference devices-based MEG system while being better suited for

Neuroelectric source localization by random spatial sampling [PDF]

open access: yes, 2016
The magnetoencephalography (MEG) aims at reconstructing the unknown neuroelectric activity in the brain from the measurements of the neuromagnetic field in the outer space.

Cortical correlation structure of aperiodic neuronal population activity

open access: yesNeuroImage, 2021
Electrophysiological population signals contain oscillatory and non-oscillatory aperiodic (1/frequency-like) components. So far research has largely focused on oscillatory activity, and only recently, interest in aperiodic population activity has gained ...

Sequential Monte Carlo samplers for semilinear inverse problems and application to magnetoencephalography [PDF]

open access: yes, 2014
We discuss the use of a recent class of sequential Monte Carlo methods for solving inverse problems characterized by a semi-linear structure, i.e. where the data depend linearly on a subset of variables and nonlinearly on the remaining ones. In this type

Magnetoencephalography in clinical practice

open access: yesArquivos de Neuro-Psiquiatria, 2022
Magnetoencephalography (MEG) is a neurophysiological technique that measures the magnetic fields associated with neuronal activity in the brain. It is closely related but distinct from its counterpart electroencephalography (EEG).

Non-parametric statistical thresholding for sparse magnetoencephalography source reconstructions. [PDF]

open access: yes, 2012
Uncovering brain activity from magnetoencephalography (MEG) data requires solving an ill-posed inverse problem, greatly confounded by noise, interference, and correlated sources.

Deep brain activities can be detected with magnetoencephalography

open access: yesNature Communications, 2019
Magnetoencephalography (MEG) is a non-invasive method of measuring neural activity but the hippocampus and amygdala are difficult to measure with MEG because of their deep localization. Here, the authors show with simultaneous MEG and invasive recordings
