Presurgical brain mapping in epilepsy using simultaneous EEG and functional MRI at ultra-high field: feasibility and first results

Wietske Van der Zwaag, João Pedro Forjaco Jorge, François Lazeyras, Giannina Rita Iannotti

OBJECTIVES: The aim of this study was to demonstrate that eloquent cortex and epileptic-related hemodynamic changes can be safely and reliably detected using simultaneous electroencephalography (EEG)-functional magnetic resonance imaging (fMRI) recordings ...

EEG-fMRI integration for the study of human brain function

Wietske Van der Zwaag, João Pedro Forjaco Jorge, Patricia Figueiredo

Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have proved to be extremely valuable tools for the non-invasive study of human brain function. Moreover, due to a notable degree of complementarity between the two modalities, th ...

Global tractography with embedded anatomical priors for quantitative connectivity analysis

Jean-Philippe Thiran, Alessandro Daducci, Alia Lemkaddem, Didrik Hans Malcolm Skiöldebrand

Tractography algorithms provide us with the ability to non-invasively reconstruct fiber pathways in the white matter (WM) by exploiting the directional information described with diffusion magnetic resonance. These methods could be divided into two major c ...

Comparison of an 8-Channel and a 32-Channel Coil for High-Resolution fMRI at 7 T

Wietske Van der Zwaag, Roy Salomon, Mayur Narsude, Jana Darulová

Multi-channel receive array rf-coils have become widely available for fMRI. The improved SNR and possibility of acquisition acceleration through parallel imaging are especially beneficial for high-resolution studies. In this study, an 8-channel and a 32-ch ...

Mapping interictal epileptic discharges using mutual information between concurrent EEG and fMRI

Dimitri Nestor Alice Van De Ville, François Lazeyras

Objective: The mapping of haemodynamic changes related to interictal epileptic discharges (IED) in simultaneous electroencephalography (EEG) and functional MRI (fMRI) studies is usually carried out by means of EEG-correlated fMRI analyses where the EEG inf ...

Sparsity-Promoting Spatiotemporal Regularization for Data Mining in Functional Magnetic Resonance Imaging

Fikret Isik Karahanoglu

Magnetic resonance imaging (MRI) has opened unprecedented avenues to observe the human brain non-invasively. In particular, for about two decades, functional MRI (fMRI) has enabled to monitor brain function using the blood-oxygen-level-dependent (BOLD) con ...

Functional MRI connectivity as a predictor of the surgical outcome of epilepsy

Roberto Martuzzi

Purpose: In planning epilepsy surgery, it is important to be able to assess the likelihood of success of surgery for each patient so that the possible risk and benefit can be properly considered. In this study, functional connectivity was investigated as ...

EEG microstate sequences in healthy humans at rest reveal scale-free dynamics

Dimitri Nestor Alice Van De Ville

Recent findings identified electroencephalography (EEG) microstates as the electrophysiological correlates of fMRI resting-state networks. Microstates are defined as short periods (100 ms) during which the EEG scalp topography remains quasi-stable; that is ...

BOLD correlates of EEG topography reveal rapid resting-state network dynamics

Dimitri Nestor Alice Van De Ville

Resting-state functional connectivity studies with fMRI showed that the brain is intrinsically organized into large-scale functional networks for which the hemodynamic signature is stable for about 10 s. Spatial analyses of the topography of the spontaneou ...

Whole-brain structural connectivity in patients with focal epilepsy studied with MRI diffusion spectrum imaging (DSI)

Jean-Philippe Thiran, Tobias Kober, Reto Meuli, Leila Cammoun, Alia Lemkaddem, François Lazeyras, Christoph Michel

In patients with focal epilepsy, diffusion MRI often reveals structural changes extending beyond visible lesions or show structural abnormalities even when the clinical scans are normal. MR Tractography based on diffusion tensor imaging allows non-invasive ...
