Magnetoencephalography has a number of distinct advantages over electroencephalography, in that first of all it requires neither reference points nor contact with the skin, and no errors arise as a result. Because the skull has high impedance, the electroencephalogram is always blurred, but the magnetoencephalogram is penetrated, and in addition, the magnetoencephalogram can directly reflect the activity state of a field source in the brain, particularly can display the activity state of a field source in the deep brain, and can more accurately determine the strength and the position of the field source by inverting the magnetoencephalogram. Such as epilepsy, brain tumor, brain trauma, cerebrovascular disease, encephalitis, etc., can cause the change of the brain magnetic field.
