We investigate a new generation of magnetoencephalography system. The hardware develops a sensor that uses the magnetic effect of atomic spins to realize a technique for measuring weak magnetic fields. The Spin Exchange Retardation Free (SERF) atomic magnetometer is a new type of light-pumped atomic magnetometer that has gained rapid development in recent years. By eliminating the atomic system tracking retardation due to spin exchange collisions, the SERF magnetometer is two orders of magnitude more sensitive than conventional light-pumped magnetometers under the same physical conditions. In addition, the SERF magnetometer is equipped with an adapted analysis software (i.e., MEG Processor) for use not only with the new pMEG but also with existing MEG magnetoencephalography, complete big data processing and analysis, fusion with conventional images such as CT/MIR, complete documentation and accurate localization, and Magnetic Source Locator (MSL), a tool necessary for advanced brain function studies. Source Locator (MSL), a technical software package for imaging functional brain activity; BrainX for brain science, brain behavior, neurological function, magnetoencephalography (MEG), electroencephalography (EEG), functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), etc.
