A magnetoencefalografia. Aplicações Clínicas.

Abstract

Magnetoencephalography (MEG) is a technique that enables the measurement of the magnetic fields produced by the brain. It is a noninvasive method that allows, similarly to electroencephalography (EEG), to follow the evolution of electrophysiological processes in the millisecond scale. It is used for localizing functional regions of the brain, with a better spatial resolution than EEG, and for assessing the health of sensory pathways. The most important clinical applications of MEG are the presurgical functional localization and the localization of epileptiform activity.
