  • Abstract
  • Look Inside

Development of magnetoencephalographic study on epilepsy was reviewed historically. Clinical application of magnetoencephalography (MEG) in epileptology has been almost exclusively dependent on the method of localization of spike generator by means of single dipole fit. There are, however, various problems in this method. One of them is from neurophysiological point of view, namely, intracortical propagation of spike activity and consequential inadequacy of the single dipole fitting. Another is the apparent asynchrony of MEG spikes and corresponding EEG spikes which makes it difficult to identify generators of them.
