The new diagnostic procedure uses magnetoencephalography (MEG), a way of monitoring the flow of electrical signals along the brain's neural pathways from cell to cell. By using a helmet with 248 noninvasive sensors arrayed around the head, scientists can map patterns of electrical activity inside the skull and detect abnormalities. The Minnesota researchers used MEG to assess 74 U.S. veterans believed to be suffering from PTSD...
