[measurement of magnetic activity of the brain, usually conducted externally by sensitive devices such as SQUID's; electric currents generated in the brain by neural activity are accompanied by orthogonal magnetic fields and the measurement of these fields provide information about the localization of brain activity which is complementary to that provided by electroencephalography.
