Epileptic seizure localized by whole head MEG
1 Introduction Magnetoencephalography (MEG) is currently used clinically for presurgical localization of epileptic tissue, based on signals from interictal spikes, using single equivalent current dipole (ECD) modeling [1,2,3,4]. There has been a long-standing question " Do interictal spikes co-localize to the same area as epileptic seizures? " Minassin, et al. found that the interictal MEG loca...
متن کاملSimultaneous EEG/MEG and ECoG source characterization of interictal spikes
For some TLE patients that do not respond the pharmacological treatment, epilepsy surgery is an option. In those cases, the determination of the location of the sources and the sequence in which they become active is of prime importance. In this paper, we investigate the interpretability and validity of dipole source localization based on EEG, MEG and simultaneous EEG+MEG for TLE interictal spi...
متن کاملIctal magnetoencephalographic discharges from elementary visual hallucinations of status epilepticus.
PURPOSE To report the rare opportunity to study ictal magnetoencephalography (MEG) in a 26 year old man with simple partial status epilepticus that presented as elementary visual hallucinations (EVHs) in the right upper visual field. METHODS The patient described his EVHs as "snowing on TV," "flickering lights," and "rotating coloured balls" that continued for several days. MEG and simultaneo...
متن کاملHigh resolution spatio-temporal EEG-MEG analysis of rolandic spikes.
Using high resolution EEG and MEG and a realistic volume conductor model, the authors investigated spatio-temporal aspects of the sources of spikes in children with benign rolandic epilepsy. A 64-channel EEG and simultaneous 151-channel MEG of interictal spike activity in five children all having general and/or focal seizures were recorded. A spatio-temporal multiple signal classification (MUSI...
متن کاملMagnetoencephalographic mapping of interictal spike propagation: a technical and clinical report.
Distinguishing propagated epileptic activity from primary epileptic foci is of critical importance in presurgical evaluation of patients with medically intractable focal epilepsy. We studied an 11-year-old patient with complex partial epilepsy by using simultaneous magnetoencephalography (MEG) and electroencephalography (EEG). In EEG, bilateral interictal discharges appeared synchronous, wherea...
