ESI and fMRI of interictal and ictal epileptic discharges
A major challenge in planning and performing resective surgery in drug-resistant epilepsy is the accurate identification of the epileptogenic zone. Currently, intracranial EEG is considered to be the most reliable preresective functional localisation method. Our objective is to non-invasively localise the epileptogenic zone using simultaneous high-density EEG source imaging (ESI) and fMRI of in...
متن کاملSimultaneous intracranial EEG and fMRI of interictal epileptic discharges in humans
Simultaneous scalp EEG-fMRI measurements allow the study of epileptic networks and more generally, of the coupling between neuronal activity and haemodynamic changes in the brain. Intracranial EEG (icEEG) has greater sensitivity and spatial specificity than scalp EEG but limited spatial sampling. We performed simultaneous icEEG and functional MRI recordings in epileptic patients to study the ha...

متن کاملImaging haemodynamic changes related to seizures: Comparison of EEG-based general linear model, independent component analysis of fMRI and intracranial EEG
BACKGROUND Simultaneous EEG-fMRI can reveal haemodynamic changes associated with epileptic activity which may contribute to understanding seizure onset and propagation. METHODS Nine of 83 patients with focal epilepsy undergoing pre-surgical evaluation had seizures during EEG-fMRI and analysed using three approaches, two based on the general linear model (GLM) and one using independent compone...
متن کاملEEG-fMRI study of the ictal and interictal epileptic activity in patients with eyelid myoclonia with absences.
PURPOSE To investigate the blood oxygenation level-dependent (BOLD) signal changes correlated with ictal and interictal epileptic discharges using electroencephalography-correlated functional magnetic resonance imaging (EEG-fMRI) in patients with eyelid myoclonia with absences (EMA) and then to explore the pathophysiological mechanisms of epileptic discharges and their effect on brain function....
