MEG measures small electrical currents arising inside the neurons of the brain. These currents produce small magnetic fields. MEG generates a remarkably accurate representation of ... The advantage of MEG over EEG is therefore greater accuracy owing to the minimal distortion of the signal. ... In the evaluation of epilepsy,

The principle features of MEG are ... MEG is a direct measure of brain function, unlike functional measures such as fMRI, PET and SPECT that are secondary measures of brain function reflecting brain metabolism. MEG has a very high temporal resolution. ... Magnetic fields are found whenever there is a current flow,
