A technique of brain imaging that measures the magnetic fields created by the induction of electrical activity of nerve cells. Unlike conventional EEG that detects radially oriented electrical activity, which is perpendicular to the cortical surface, MEG measures activity tangentially, with less scalp-induced distortion than EEG.
