The NeuroMagnetic Brain Imaging laboratory houses a state-of-the-art Elekta Neuromag-Triux Magnetoencephalography (MEG) system equipped with 306 MEG channels and 64 Electroencephalography (EEG) channels integrated for simultaneous recording of electro-magnetic brain activity. MEG is a neurophysiology recording technology that measures very small magnetic fields produced by synchronized neural activity in the brain and allows for exquisite spatiotemporal imaging of brain function. This is accomplished via specialized super-conducting sensors that map activity in the brain such as epilepsy. The procedure is totally non-invasive and therefore can be applied to adults and children.
In our MEG imaging center, we can pinpoint brain localizations of epilepsy and essential “eloquent” functional cortex which involves speech comprehension, somatosensory and motor functions. These procedures are considered a part of pre-surgical evaluation of neurosurgical candidates that are being treated for Medically Intractable Epilepsy or Brain Tumor.

The MEG evaluation is highly recommended for patients who potentially may consider brain pacemaker to suppress an ictal activity in the brain. However, a clinical-research study recently published in Epilepsy Research Journal demonstrated the high level of better outcomes for patients who undergo brain surgery who did have MEG evaluation prior to the surgery as compared to those who did not.

For MEG mapping we are requesting the anatomical brain images (e.g., MRI), which allow us to overlay MEG data and structural anatomical data (MRI) visualization of MEG results by the neurologist/neurosurgeon.
