Magnetoencephalography as a tool to identify high frequency brain signals in pediatric patients with epilepsy

Takeaway

  • Magnetoencephalography (MEG) may be a non-invasive method to help distinguish pathological from physiological high frequency brain signals (HFBS) and in doing so, may help to provide useful information to guide clinical invasive recordings and direct the surgical treatment of epilepsy.

Why this matters

    Intracranial studies have shown HFBS to be a novel biomarker for epilepsy, however, it can be difficult to distinguish if such HFBS are pathological (i.e. epileptic) or physiological in origin.
