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.

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 and normal pressure hydrocephalus: A case report [PDF]

open access: yesJournal of Integrative Neuroscience, 2018
In a case study of an 82-year old male spontaneous magnetoencephalography recordings revealed lower magnetic fields at frontal and frontotemporal regions compared to central and posterior regions.

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 ...

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.

The lifespan trajectory of neural oscillatory activity in the motor system

open access: yesDevelopmental Cognitive Neuroscience, 2018
Numerous studies connect beta oscillations in the motor cortices to volitional movement, and beta is known to be aberrant in multiple movement disorders.

Response certainty during bimanual movements reduces gamma oscillations in primary motor cortex

open access: yesNeuroImage, 2021
Even when movement outputs are identical, the neural responses supporting them might differ substantially in order to adapt to changing environmental contexts.

Multi-spectral oscillatory dynamics serving directed and divided attention

open access: yesNeuroImage, 2020
Attention-related amplification of neural representations of external stimuli has been well documented in the visual domain, however, research concerning the oscillatory dynamics of such directed attention is relatively sparse in humans. Specifically, it

Development and sex modulate visuospatial oscillatory dynamics in typically-developing children and adolescents

open access: yesNeuroImage, 2020
Visuospatial processing is a cognitive function that is critical to navigating one's surroundings and begins to develop during infancy. Extensive research has examined visuospatial processing in adults, but far less work has investigated how visuospatial
