Anda Popescu, a physicist with the Magnetoencephalography (MEG) Laboratory at the National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center in Bethesda, Md., attaches sensors to a subject's head March 21, 2017. Unlike its cousin, the more commonly used electroencephalography (EEG), the MEG brain scan can see changes in structures that reside deep in the brain tissue. By measuring minute changes in magnetic fields generated by the cerebral cortex while resting, while thinking and while engaged in some particular task, deficits in the brain can be measured and localized.
