Magnetoencephalography: Clinical and Research Practices.Magnetoencephalography (MEG) is a neurophysiological technique that detects the magnetic fields associated with brain activity.  Synthetic aperture magnetometry (SAM), a MEG magnetic source imaging technique, can be used to construct both detailed maps of global brain activity as well as virtual electrode signals, which provide information that is similar to invasive electrode recordings.  For individuals with epilepsy, MEG provides valuable, nonredundant information.  MEG accurately localizes the irritative zone associated with interictal spikes, often detecting epileptiform activity other methods cannot, and may give localizing information when other methods fail.  MEG methods can be readily adapted to research settings, allowing noninvasive assessment of whole brain neurophysiological activity, with a theoretical spatial range down to submillimeter voxels, and in both humans and nonhuman primates.  The combination of clinical and research activities with MEG offers a unique opportunity to advance translational research from bench to bedside and back.
