Magnetoencephalography (MEG) is an imaging technique that maps brain activity by recording magnetic fields produced by electrical currents in the brain. Unlike electroencephalography, which uses electrodes attached to the head, MEG uses sensors positioned over the head and takes place in a vaultlike machine that eliminates interference from magnetic fields produced by various sources. MEG is sometimes used to pinpoint areas of pathological activity before surgery to treat what conditions?
