Magnetoencephalography in pediatric epilepsy
Magnetoencephalography (MEG) records the magnetic field generated by electrical activity of cortical neurons. The signal is not distorted or attenuated, and it is contactless recording that can be performed comfortably even for longer than an hour. It has excellent and decent temporal resolution, especially when it is combined with the patient's own brain magnetic resonance imaging (magnetic so...
متن کاملMagnetoencephalography of focal cerebral ischemia in rats.
BACKGROUND AND PURPOSE The purpose of this study was to use magnetoencephalography to record magnetic field changes in the brain during middle cerebral artery occlusion. METHODS A direct-current electrocorticogram (two channels) and a direct-current magnetoencephalogram (seven channels) were simultaneously recorded from five rats subjected to middle cerebral artery occlusion for 1-2 hours. ...
متن کاملMagnetoencephalography in the presurgical evaluation of epilepsy.
Magnetoencephalography (MEG) is an important tool in the presurgical evaluation of patients with medically refractory epilepsy. The appropriate utilization and interpretation of MEG studies can increase the proportion of patients who may be able to further pursue surgical evaluation, refine surgical planning, and potentially increase the probability of seizure freedom after surgery. The aim of ...
متن کاملMagnetoencephalography in Pediatric Lesional Epilepsy Surgery
This study was performed to assess the usefulness of magnetoencephalography (MEG) as a presurgical evaluation modality in Korean pediatric patients with lesional localization-related epilepsy. The medical records and MEG findings of 13 pediatric patients (6 boys and 7 girls) with localization-related epilepsy, who underwent epilepsy surgery at Seoul National University Children's Hospital, were...
متن کاملNeuropsychiatric morbidity in focal epilepsy.
BACKGROUND Previous work has identified elevated prevalence rates for psychiatric disorders in individuals with medically refractory focal epilepsy, particularly temporal lobe epilepsy. Many studies were undertaken before the advent of video electroencephalogram monitoring (VEM) and magnetic resonance imaging (MRI). AIMS To investigate which characteristics of the focal epilepsy syndromes are...
