Abstract
Magnetoencephalography(MEG) has many advantages over the electroencephalography (EEG) as it detects the magnetic fields originating from the intracellualr currents within neurons, which are not attenuated or distorted by intervening tissues. Over the several years, it has developed to a whole-head system that enables its routine clinical application for epilepsy patients. MEG is indicated for localization of the irritative zone in lesional and nonlesional epilepsy surgery patients, with having the superiority in neocortical epilepsy, functional mapping of eloquent cortex and defining its relationship with the brain lesion or epileptogenic area, and assessment of normal and abnormal language development. Because of its high spatial and temporal resolution, MEG provides promises to be a powerful tool in the investigation of normal and abnormal brain function including sensory, motor, memory and cognitive processes in the developing brain in the future.
