What is MEG?

 

What is MEG?

Magnetoencephalography (MEG) is a completely non-invasive, non-hazardous neuroimaging method that measures electromagnetic signals generated by the human brain. It detects magnetic flux occurring at the scalp surface by underlying intracellular electrical currents in the brain. Signals arise from synchronous firing of a large number of neurons across several layers of the cortex. The MEG system utilizes a two layer array of 375 magnetometers to provide extremely sensitive spatial information about brain activity in real time. MEG provides direct, real-time monitoring of the dynamics of neural signals with high spatial (several millimeters to couple centimeters) and temporal (milliseconds) resolution.

Projects and Studies

Research

In addition to its clinical function, MEG is also a valuable research tool for helping our scientists gain insight to a variety of neurodevelopmental disorders including Cerebral Palsy, Autism Spectrum Disorders, Down Syndrome, Tuberous Sclerosis Complex, Fetal Alcohol Syndrome, as well as hearing impairments, vision deficits, and focal brain malformations.

Clinical

Clinically, MEG is most often used to localize seizure activity in patients with epilepsy. Since FDA approval in April 2016, the BabyMEG has been used to evaluate several children with refractory epilepsy prior to surgery. Clinical MEG measurements can assist physicians and surgeons by localizing interictal and ictal activity as well as eloquent areas of the brain.
