A new study reveals something that shouldn't come as much of a surprise: the brains of people with PTSD are hyperactive even when they are "relaxed."
Using a technique called magnetoencephalography or MEG, researchers found that people with PTSD have heightened activity in the right-hand hemisphere of their brains. According to a report from HealthDay, "Compared with the healthy 'controls,' the PTSD patients showed 'hyperactive' communication between the temporal cortex -- the part of the brain thought to be responsible for reliving past experiences -- and two other areas on the right side of the brain."
This hyperactivity was present even though the patients were in a relaxed state for the MEG scan.
The study was published in the Journal of Neural Engineering. The paper is available free online for a limited time.
