On Linearly Constrained Minimum Variance Beamforming [PDF]

, 2015
Beamforming is a widely used technique for source localization in signal processing and neuroimaging. A number of vector-beamformers have been introduced to localize neuronal activity by using magnetoencephalography (MEG) data in the literature ...

Using cluster‐based permutation tests to estimate MEG/EEG onsets: How bad is it?

European Journal of Neuroscience, Volume 61, Issue 1, January 2025.
Cluster‐sum inferences, popular in EEG and MEG research, offer weak control over the familywise error rate and formally cannot be used to make inferences about onsets. However, simulations demonstrate that cluster‐sum compares favourably to other methods in terms of bias and mean absolute error (MAE).

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.

Structural and functional brain alterations in laryngeal dystonia: A coordinate‐based activation likelihood estimation meta‐analysis

Human Brain Mapping, Volume 45, Issue 14, October 2024.
A coordinate‐based activation likelihood estimation meta‐analysis of 21 functional and structural neuroimaging studies in laryngeal dystonia, including 31 experiments in 521 patients and 448 healthy controls, identified abnormalities in the bilateral primary motor cortex, the left inferior parietal lobule and striatum, the right insula, and the ...

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 ...

EEG/MEG source imaging of deep brain activity within the maximum entropy on the mean framework: Simulations and validation in epilepsy

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
We proposed depth‐weighted Maximum Entropy on the Mean (MEM) methods for EEG/MEG source imaging and evaluated using realistic EEG/MEG simulations and EEG/MEG recordings from patients with focal epilepsy. The proposed method improved localization for deep sources without worsening the superficial source reconstructions compared to standard MEM and depth

Effects of endogenous testosterone on oscillatory activity during verbal working memory in youth

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
During puberty, endogenous testosterone levels rise. We examined whether these increases in testosterone are associated with developmental changes, controlling for age, in the neural oscillatory dynamics serving verbal working memory. Results showed that alpha and theta oscillatory responses were modulated by testosterone levels across multiple regions

Optimal gamma‐band entrainment of visual cortex

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
Visual entrainment of primary visual cortex was robust across three different driving frequencies in the gamma‐band (32, 40, 48 Hz). This entrainment of primary visual cortex was strongest for the 32 and 40 Hz, relative to 48 Hz, driving frequencies.

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.

What we leave behind: poetry, music, and Seamus Heaney [PDF]

, 2017
Seamus Heaney’s death in late summer, 2013, came as a shock and is now a residual sadness. I miss his guidance, his humanity, his humor. Heaney’s presence, through the poems, has been a richly-colored thread connecting each stage of my life—or at least ...
