In quest for autism biomarkers, this technique has magnetic appeal
To find biological markers of autism, scientists would be wise to measure the brain’s electrical activity along with the resulting magnetic fields.

A brain imaging technique called magnetoencephalography characterizes not just what is happening in the brain, but also where and when, making it ideally suited for studying autism.
There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.
