A recent study has revealed that the recurrences of the previous events faced by people suffering from post-traumatic stress disorder (PTSD) are linked with the increased hyperactivity on the right side of the brain.

The research was conducted by the researchers at the University of Minnesota in Minneapolis involving 80 people with PTSD, 18 with reduction in the PTSD condition and 284 those with not having the disorder.

A technique called magnetoencephalography or MEG was employed by the researchers, in order to examine the magnetic charges released when there is connection and interaction between neurons in the brain. The participants were made to wear a MEG helmet when they were shown a spot for a minute at a distance of 65 centimeters.

It was found that there was increased hyperactivity between the temporal cortex (the part of the brain that recalls past experiences) and two other parts on the right side of the brain in comparison to the controlled subjects. Less but the same hyperactivity was found in PTSD patients in remission, while those not affected with the condition showed no upheaval in the brain.

Dr. Apostolos Georgopoulos, the study leader said, "Having a diagnostic exam capable of confirming post-traumatic stress disorder is critical in treating these patients properly".

The findings of the study appeared in the Journal of Neural Engineering.
