Resumen de Wearable scanner snaps moving brains
Magnetoencephalography (MEG) involves analysing the brain's electrical activity via the magnetic fields it generates just outside the skull. Richard Bowtell at the University of Nottingham, UK, and his colleagues have designed a portable MEG device that is worn like a helmet, allowing people to move freely during scanning. The device was made portable by replacing traditional sensors, which require a heavy and bulky cooling system, with miniature ones that detect the brain's magnetic field in a different way.
