Novel underlying mechanism involved in PTSD and other anxiety disorders described

A novel mechanism has been identified for how stress-induced anxiety — which can produce post-traumatic stress disorder, or PTSD — affects circuit function in the hippocampus, the area of the brain where aversive memories are formed. These studies fill an important gap in knowledge between the molecular, circuit and behavioral effects of the brain-signaling molecule called neuropeptide Y, and could lead to new therapeutic targets for patients with anxiety disorders….
