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.

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.

Navigating Correlation, Causation, and Interpretation in Resting-State fMR

This paper examines limitations in interpreting resting-state fMRI correlations, distinguishing measurement distortion from causal non-identifiability and their implications for biological interpretation.

NIRSTORM: a Brainstorm extension dedicated to functional Near Infrared Spectroscopy (fNIRS) data analysis, advanced 3D reconstructions, and optimal probe design.

NIRSTORM extends Brainstorm for fNIRS analysis, offering 3D hemodynamic reconstructions and optimal probe design within a multimodal framework.

Through the lens of causal inference: Decisions and pitfalls of covariate selection

The paper highlights pitfalls in covariate selection and advocates for principled approaches to improve statistical validity and reproducibility in data analysis.

Assessing cortical excitability with electroencephalography: a pilot study with EEG-iTBS.

This study evaluates EEG-based measures of cortical excitability before and after iTBS in healthy subjects, finding that gamma band phase consistency correlates with excitability changes in M1.

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.

Hierarchical Bayesian Modeling of the Relationship between Task Related Hemodynamic Responses and Neuronal Excitability: a Simultaneous fNIRS/TMS Study

This study uses hierarchical Bayesian modeling to analyze how PAS stimulation affects cortical excitability and hemodynamic responses, finding a positive correlation between the two.

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.

Diffuse optical reconstructions of NIRS data using Maximum Entropy on the Mean

This paper introduces a new fNIRS reconstruction method called Maximum Entropy on the Mean (MEM), which provides more accurate and robust reconstructions than the Minimum Norm Estimate (MNE) in both simulations and real data.
