HIPPOCAMPAL TAU RELATED SIGNAL INDEXES HYPEREXCITABILITY AND NREM SLEEP MEMORY DYSFUNCTION IN TEMPORAL LOBE EPILEPSY

This study links higher hippocampal 18F-MK6240 uptake in TLE to increased seizure burden, altered NREM sleep microstructure, and impaired memory.

Pathology in resected areas of FDG PET hypometabolism in pediatric epilepsy patients with focal cortical dysplasia type II

The paper examines histopathology in FDG-PET hypometabolic regions of pediatric epilepsy patients with FCD type II, finding fFCD concentrated at the lesion epicenter and DNO present in both epicenter and hypometabolic borders.

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.

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.

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.

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.

Identification of negative BOLD responses using windkessel models

The paper identifies five mechanisms of negative BOLD responses and develops a windkessel model to detect, classify, and estimate these mechanisms from fMRI data.
