Abstract

People with pharmacoresistant epilepsy are often candidates for resective epilepsy surgery. The presurgical evaluation for epilepsy aims to localize the epileptic network that initiates seizures (which should be disrupted or removed) and determine its spatial relationship to eloquent cortex (which should be preserved). Noninvasive functional imaging techniques play an increasingly important role in planning epilepsy surgery and assessing the feasibility, risks, and benefits of surgery. Magnetoencephalography (MEG) can be a very useful part of a comprehensive presurgical evaluation as it can model the sources of epileptiform activity and localize eloquent cortices within the same study. This review is designed to assist anyone in the field of neurology or related disciplines understand some methods and terminology relevant to clinical MEG. Every effort is made to present the information in nontechnical, approachable ways so that readers will come away with a basic understanding of how to interpret MEG findings when the reported data on one of their patients are presented to them.
