Optimization of epilepsy surgery through virtual resections on individual structural brain networks

Scientific Reports, 2021
The success of epilepsy surgery in patients with refractory epilepsy depends upon correct identification of the epileptogenic zone (EZ) and an optimal choice of the resection area. In this study we developed individualized computational models based upon

The Neural Oscillatory Basis of Perspective‐Taking in Autistic and Non‐Autistic Adolescents Using Magnetoencephalography

European Journal of Neuroscience, Volume 61, Issue 8, April 2025.
ABSTRACT Taking another's perspective is a high‐level mental skill underlying many aspects of social cognition. Perspective‐taking is usually an embodied egocentric process whereby people mentally rotate themselves away from their physical location into the other's orientation.

Altered Functional Connectivity Dynamics Serving Cognitive Flexibility in Regular Cannabis Users

Addiction Biology, Volume 30, Issue 3, March 2025.
To examine the effects of chronic cannabis use on the oscillatory dynamics serving cognitive flexibility, users and non‐users completed a task‐switching paradigm during magnetoencephalography. Users displayed altered associations between functional connectivity switch costs and behavioural switch costs along pathways linking visual cortices and ventral

Pseudo‐MRI Engine for MRI‐Free Electromagnetic Source Imaging

Human Brain Mapping, Volume 46, Issue 2, February 1, 2025.
A tool, pseudo‐MRI engine, was implemented to generate subject‐specific template MRIs based on scalp digitization that can readily be used for MEG/EEG source imaging. The geometrical and source‐imaging similarity with real MRI proves that the method can be an alternative to individual MRIs in various MEG/EEG applications.

Rapid Cortical Plasticity Induced by Active Associative Learning of Novel Words in Human Adults

Frontiers in Neuroscience, 2020
Human speech requires that new words are routinely memorized, yet neurocognitive mechanisms of such acquisition of memory remain highly debatable. Major controversy concerns the question whether cortical plasticity related to word learning occurs in ...

Magnetoencephalography-identified preictal spiking correlates to preictal spiking on stereotactic EEG

Epilepsy & Behavior Reports, 2022
Magnetoencephalography (MEG) is a noninvasive diagnostic modality that directly measures neuronal signaling by recording the magnetic field created from dendritic, intracellular, electrical currents of the neuron at the surface of the head.

Human cortical high‐gamma power scales with movement rate in healthy participants and stroke survivors

The Journal of Physiology, Volume 603, Issue 4, Page 873-893, 15 February 2025.
Abstract figure legend Magnetoencephalography data from stroke survivors, healthy, age‐matched control participants and healthy young participants were measured during the execution of a thumb movement task. Movement‐related high‐gamma power was evident in all three groups with a maximum over motor cortical areas contralateral to the performed movement.

Maturation of auditory neural processes in autism spectrum disorder — A longitudinal MEG study

NeuroImage: Clinical, 2016
Background: Individuals with autism spectrum disorder (ASD) show atypical brain activity, perhaps due to delayed maturation. Previous studies examining the maturation of auditory electrophysiological activity have been limited due to their use of cross ...
