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.

Current Studies

Autism is a neurodevelopmental disorder that is associated with impairments in reciprocal social interaction, communication, and stereotyped, restricted, and repetitive patterns of interests and behaviors. Language and communication abnormalities occur across the entire autism spectrum disorders (ASD) at varying degrees and are very important in the diagnosis of ASD.  We are interested in studying the brain correlates of psycholinguistic processes in typically developing children, children with ASD, and children who are at high risk for developing ASD. Our findings will help understand the brain mechanisms of language and communication problems seen in ASD and hope that our findings will shed light on identifying early biomarkers for this disorder.
