Dynamic functional connectivity is modulated by the amount of p-Tau231 in blood in cognitively intact participants

The paper examines the relationship between dynamic functional connectivity measured by magnetoencephalography and plasma p-tau231 levels in cognitively intact participants, finding a positive association between frontotemporal connectivity and p-tau231.

The fluctuations of alpha power: bimodalities, connectivity, and neural mass models

This study examines dynamic alpha power fluctuations, their relationship with functional connectivity, and the ability of a neural mass model to replicate these patterns using MRI and MEG data.

EEG Electrodes and Where to Find Them: Automated Localization From 3D Scans

This paper presents a method for accurately localizing EEG electrode positions using 3D scans, validated on a large dataset, achieving 85.7% to 91.0% accuracy without requiring MRI.

When Maturation is Not Linear: Brain Oscillatory Activity in the Process of Aging as Measured by Electrophysiology

This study uses regression models to analyze MEG power changes across age and brain regions, revealing non-linear trajectories and associations with cognitive performance and gray matter volume.

From electrophysiology to drink: Adolescent alcohol consumption predicted by differences in functional connectivity and neuroanatomy

The paper predicts adolescent alcohol consumption using neuroanatomical and functional connectivity variables from MEG data in a cohort of 14-16 year olds.

Dynamics of Brain Connectivity across the Alzheimer's Disease Spectrum: a magnetoencephalography study

This study examines dynamic functional connectivity changes across Alzheimer's disease stages using MEG, finding reduced connectivity in specific brain regions and its correlation with cognitive decline and structural brain changes.

Modified MRI anonymization (de-facing) for improved MEG coregistration

This paper introduces an improved MRI de-facing method that retains the nose, enhancing MEG/EEG coregistration while maintaining privacy.

Tactile attention modulates occipital alpha oscillations in early blindness

The paper investigates whether alpha oscillations in early blind individuals are modulated by tactile attention, finding that occipital alpha activity is sensitive to task-dependent factors despite reduced amplitude.

Cluster-permutation statistical analysis for high-dimensional brain-wide functional connectivity mapping

This paper introduces a cluster-permutation statistical method for high-dimensional MEG-based functional connectivity analysis, identifying hypersynchronization in MCI patients.

Heart evoked brain oscillatory networks and its interruption in early stages of Alzheimer’s disease
