(University of Alabama at Birmingham) Neurobiologist Lynn Dobrunz has discovered a novel mechanism 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.
