Synchronized extracellular currents in a few square centimeters of cortex generate magnetic fields measurable with sensors on the surface of the scalp. The biggest advantage of MEG, as compared with electroencephalography (EEG), is its high spatial resolution due to less of an effect of cerebrospinal fluid, skull, and skin, since magnetic fields are not affected by electric current conductivity.
