Scientists at the University of Nottingham are working with University College London (UCL) on a five-year project which has the potential to revolutionise the world of human brain imaging.Magnetoencephalography (MEG) is a technique for mapping brain activity - it measures the magnetic fields generated by electrical currents that occur naturally in the brain. A £1.6m Collaborative Award in Science from Wellcome is funding the construction of a new type of MEG scanner which, if successful, could quadruple the sensitivity of current devices.The project is a collaboration between the University of Nottingham and University College London.
