Magnetoencephalography (MEG)

Magnetoencephalography (MEG) is an advanced non-invasive functional brain imaging technique which measures the magnetic fields emitted by brain cells (neurons), which can display the location of brain activity, as it occurs in real time.

Along with being used to localize epileptic discharges in the brains of patients with seizures, MEG also localizes major functional centers in the brain that control movement, sensation, hearing, vision, and language, important for pre-surgical planning in neurosurgery.

MEG is also a powerful research tool, enhancing our understanding of human brain function. It is being used to study a number of neurological disorders such as epilepsy and stroke, as well as psychiatric disorders such as schizophrenia, dementia, and posttraumatic stress disorder.

Roland Lee, MD, is the director of the our magnetoencephalography services.
