What Is Magnetoencephalography?
The subject's head is placed in a particularly sensitive ultra-cold electromagnetic measuring device, and the very weak brain magnetic waves of the brain can be measured by a special instrument. The brain magnetic waves are recorded by a recording device to form a pattern. Such graphics are called magnetoencephalograms.

- There is also a magnetic field around the human skull. This magnetic field is called the brain magnetic field. However, this magnetic field strength is very weak, and it can be measured and recorded with special equipment. It is necessary to establish a tight electromagnetic field shielding room. In this shielding room, the subject's head is placed in a particularly sensitive ultra-cold electromagnetic measuring device, and the very weak brain magnetic waves of the brain can be measured by special instruments. This recording is then used to record this brain magnetic wave to form a pattern. This pattern is called a magnetoencephalogram. It reflects the change of the magnetic field of the brain, which is different from the change of the electric field of the brain reflected by EEG. Magnetoencephalography is more accurate in the diagnosis of brain injury than EEG. In addition, the magnetoencephalography is not affected by the skull, and the image is clear and easy to identify. Therefore, it is a new method for brain diseases. The role of EEG should be combined with EEG, and complementarity is insufficient. EEG is susceptible to interference from excessive electrical activity, and is also affected by the skull, attenuation of amplitude, etc., and its diagnosis is more accurate.
