An improved method for recording brain activity could prove a major asset to neuroscience, according to a Nature paper just out: Moving magnetoencephalography towards real-world applications with a wearable system
The new device is an improved version of an existing technique, called magnetoencephalography (MEG). MEG scanners detect magnetic fluctuations caused by the brain’s electrical activity. Existing MEG devices, however, are bulky, expensive installations, because they rely on liquid-helium-cooled sensors, called SQUIDS.
