BUSM researchers move one step closer to understanding brain
Researchers at Boston University School of Medicine (BUSM) and the VA Boston Healthcare System are one step closer to understanding the specific nature of brain changes associated with Posttraumatic Stress Disorder (PTSD).

Guided by evidence that this network can be subdivided into distinct parts that have specialized functions, Danielle R. Miller, PhD, and her colleagues studied the communication within this network of brain regions in more detail. Sixty-nine returning war Veterans with PTSD and 44 Veterans with a history of trauma but without PTSD underwent functional Magnetic Resonance Imaging (fMRI) of the brain to measure brain activity through blood flow.

The researchers found that in Veterans with PTSD, disruptions of the aforementioned network affected specifically the communication between brain regions involved in memory...
