Frequency‐Resolved Cortical Functional Connectivity Across the Adult Lifespan

Human Brain Mapping, Volume 47, Issue 4, March 2026.
An analysis of magnetoencephalography (MEG) recordings from 576 adults aged 18–87 years revealed frequency‐dependent changes in cortical functional connectivity across the adult lifespan, which are not explained by changes in source power. Beta‐band (13–30 Hz) connectivity at rest is associated with sensorimotor attenuation independent of these age ...

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 ...

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.

Maturation of auditory cortex neural responses during infancy and toddlerhood

NeuroImage, 2023
The infant auditory system rapidly matures across the first years of life, with a primary goal of obtaining ever-more-accurate real-time representations of the external world.

The Mismatch Negativity Compared: EEG, SQUID‐MEG, and Novel 4Helium‐OPMs

Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.
In this study, we compared the mismatch negativity (MMN), evoked by an auditory oddball paradigm, between EEG, cryogenic SQUID‐MEG, and a novel prototype Helium‐OPM system. Results show high similarity in the evoked time courses and signal‐to‐noise ratios, showing potential for reliable application of OPM‐MEG in MMN research, including routine clinical

Event‐Marked Windowed Communication: Inferring Activity Propagation from Neural Time Series

Human Brain Mapping, Volume 46, Issue 8, June 1, 2025.
Event‐marked Windowed Communication (EWC)—a pipeline to estimate communication patterns from regional neural recordings. EWC captures inter‐regional communication by first identifying spontaneous, endogenous perturbations, or “events”, from neural recordings, and then tracking their propagation by gauging post‐perturbation statistical effects on ...

Alpha activity neuromodulation induced by individual alpha-based neurofeedback learning in ecological context: a double-blind randomized study

Scientific Reports, 2021
The neuromodulation induced by neurofeedback training (NFT) remains a matter of debate. Investigating the modulation of brain activity specifically associated with NF requires controlling for multiple factors, such as reward, performance, congruency ...

Synaptic Function and Sensory Processing in ZDHHC9‐Associated Neurodevelopmental Disorder: A Mechanistic Account

European Journal of Neuroscience, Volume 61, Issue 9, May 2025.
In the current study, we employed a bottom‐up approach to study the impact of synaptic‐level alterations associated with ZDHHC9 variants on cortical function in healthy and ZDHHC9‐deficient participants. To achieve this, a recurrent neural network model was employed to recapitulate MEG‐derived auditory‐evoked responses and subsequently perturbed in ...

Attenuated processing of vowels in the left temporal cortex predicts speech-in-noise perception deficit in children with autism

Journal of Neurodevelopmental Disorders
Background Difficulties with speech-in-noise perception in autism spectrum disorders (ASD) may be associated with impaired analysis of speech sounds, such as vowels, which represent the fundamental phoneme constituents of human speech.
