Washington, Feb 2 (PTI) Scientists have found that a heightened activation in the amygdala of one's brain in response to seeing surprised and neutral facial expressions appears to be tied to developing post-traumatic stress disorder (PTSD).
The team, led by researchers from Tufts University, US, studied male identical twin pairs using fMRI studies of brain activation. By studying identical twins, who share the same genes, the researchers could show which traits are familial and which are not, the study said.
Understanding one's susceptibility to developing post-traumatic stress disorder (PTSD) is important.
