This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is comparing two advanced brain imaging tests — one called MEG (magnetoencephalography) and another called high-resolution EEG — to see which one better helps doctors identify exactly where seizures are starting in your brain. This information is crucial for planning epilepsy surgery. Both tests are non-invasive and simply record electrical activity in your brain using sensors placed on your scalp.
For people with epilepsy that doesn't respond to medication, surgery may be the best treatment option — but only if doctors can pinpoint exactly where in the brain the seizures begin. While both MEG and high-resolution EEG can help locate this area, no large study has directly compared which one works better in real patients, so researchers want to find out.

You will receive both a MEG scan and a high-resolution EEG recording (which uses 128 electrodes placed on your scalp) as part of your regular pre-surgery assessment. These are non-invasive tests where you sit still while the equipment records electrical signals from your brain. Some participants may also receive an intracranial EEG (electrodes placed inside the brain during surgery) as part of their standard surgical care. The study will help your surgical team get the most accurate picture of where your seizures originate.
