چکیده

There is not yet a formal definition of magnetoencephalography (MEG) spike. This study provides a parametric description and definition of clear-cut MEG spikes recorded simultaneously by MEG and depth electrodes (iEEG). A total number of 367 simultaneous MEG/iEEG spikes were selected for analysis. Distribution of morphologic spike parameters and detailed quantitative analysis of the basic morphologic characteristics of MEG spikes is provided.

Complementary use of video-electroencephalography and magnetoencephalography in frontal lobe epilepsy

PURPOSE The aim of this study was to compare magnetoencephalography (MEG) and video-electroencephalography (VEEG) source localization in frontal lobe epilepsy (FLE) and determine if these methods can be complementary to each other in clinical practice. METHOD Thirty patients with pharmaco-resistant FLE who underwent epilepsy surgery were retrospectively enrolled. Video EEG was recorded using ...

Magnetoencephalography and surgery for lesional extrahippocampal epilepsy in children

Patients with intractable epilepsy due to lesions may undergo surgical treatment of both the lesion and the seizures. The surgical plan which lesion may be completely resected and which seizures has to be controlled remains for the team of epilepsy surgery, including neurosurgeon, neurologist, and neuroradiologist. In these cases, the extent of surgical resection is sometimes guided by spikes r...

Combined EEG and MEG study of rolandic discharges in benign childhood epilepsy

Benign rolandic epilepsy of childhood (BREC) is one of the most frequent epileptic syndromes in children. Clinically the syndrome is characterized by facial motor seizures sometimes preceded by a somatosensory aura, speech arrest and by secondarily generalized tonic-clonic seizures during sleep. The prognosis is excellent and most patients become seizure-free by the age of 15 year [10, 11]. Int...

Currentodensitogram of SAM virtual sensors compared with simultaneously recorded ECoG

1 Introduction Equivalent current dipole (ECD) analysis for mag-netoencephalogram (MEG) has been useful in screening the localization of the epileptogenic zone, even though MEG was recorded in the interictal period [1] [2]. However, it requires several mathematical restrictions and often fails to estimate confidential current sources. Therefore the epileptogenic area derived from the ECD analys...

High 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...
