WHAT’S THIS PROCEDURE?

Magnetoencephalography

Magnetoencephalography (MEG) is a non-invasive medical test that measures the magnetic fields produced by your brain’s electrical currents. It’s performed to map brain function and to identify the exact location of the source of epileptic seizures.

MEG detects, records and analyses the magnetic fields produced by electrical currents in the brain. It creates a roadmap of the brain that’s useful for preoperative and treatment planning for people with epilepsy and for patients undergoing surgery to remove a brain tumour or other lesion.

MEG is also used as a research tool to help scientists better understand human brain function and to study neurological and psychiatric disorders.
