Une méthodologie basée sur une analyse en composantes indépendantes spatiale (ACI) a été développée spécifiquement pour des données d’électroencéphalographie (EEG) pour extraire des réseaux fonctionnels à large échelle. Les résultats préliminaires sont présentés dans cet article. Les données EEG ont été enregistrées chez 15 sujets effectuant une tâche visuelle. Elles ont été prétraitées et reconstruites...
Performing an accurate localization of sources of interictal spikes from EEG scalp measurements is of particular interest during the presurgical investigation of epilepsy. The purpose of this paper is to study the ability of six distributed source localization methods to recover extended sources of activated cortex. Due to the frequent lack of a gold standard to evaluate source localization methods,...
Brain imaging studies in TEP, functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have shown that visuospatial short-term memory tasks depend on dorsal parietofrontal networks. Knowing the spatiotemporal dynamics of this network would provide further understanding of the neural bases of the encoding process. We combined magnetoencephalography (MEG) with EEG and fMRI techniques...
