Assessing the Functional-Structural Reorganization of Connector Hubs in Temporal Lobe Epilepsy

This study examines how connector hubs in temporal lobe epilepsy patients reorganize compared to healthy controls, finding widespread hub reductions and new hub emergence in contralateral regions.

The electro-MICA toolbox for integrating electrophysiology within multimodal imaging and connectomics workflows

electro-MICA projects electrophysiological features onto cortical surfaces using numerical solutions to electromagnetic equations, outperforming conventional models in iEEG validation.

Human cortical dynamics reflect graded contributions of local geometry and network topography

This study shows that human cortical dynamics are influenced by both local geometry and network topology, with transmodal regions showing additional dependence on microstructural and connectivity factors.

The Hemodynamic Response Function Varies Across Anatomical Location and Pathology in the Epileptic Brain

This study identifies four distinct HRF shape groups in the epileptic brain, showing HRF variability is linked to both anatomical location and pathology.

EEG source imaging technique to investigate sleep oscillations for simultaneous EEG-fMRI

This paper applies beamforming spatial filtering to EEG-fMRI data to improve detection of sleep spindles and enhance fMRI GLM analysis by reducing BCG artefacts.

NREM sleep brain networks modulate cognitive recovery from sleep deprivation

The paper investigates how NREM sleep stages N2 and N3 modulate cognitive recovery after sleep deprivation by analyzing brain network segregation using fMRI and a new hierarchical segregation index.

Atypical connectome topography and signal flow in temporal lobe epilepsy

This study identifies atypical functional topography and reduced hierarchical signal flow in temporal lobe epilepsy, linked to microstructural white matter changes and cognitive impairments.

Validating MEG source imaging of resting state oscillatory patterns with an intracranial EEG atlas

This paper validates MEG source imaging by comparing it to an intracranial EEG atlas, finding that MEG accurately estimates oscillatory patterns in lateral regions but underestimates deep regions.

Atypical intrinsic neural timescales in temporal lobe epilepsy

This study identifies atypical intrinsic neural timescales in temporal lobe epilepsy, showing reduced timescales in multiple brain regions and high accuracy in classifying patients and lateralizing seizure foci.

Hemodynamic Correlates of Fluctuations in Neuronal Excitability: A Simultaneous Paired Associative Stimulation (PAS) and functional Near Infra-Red Spectroscopy (fNIRS) Study

This study investigates the relationship between cortical excitability and hemodynamic activity using simultaneous TMS and fNIRS, finding a positive correlation between them.

Fast oscillations >40Hz localize the epileptogenic zone: an electrical source imaging study using high-density electroencephalography

This study shows that fast oscillations >40Hz detected with high-density EEG can accurately localize the epileptogenic zone, outperforming conventional EEG methods.
