Additional Information

Dr. Hunter is fundamentally interested in how stressful or traumatic life events alter not only the course of our lives but the very structure and function of our brains as well. Why do many if not most humans and animals recover quickly from trauma and why do others go on to suffer life long impairments like depression and post traumatic stress disorder?
To  answer these questions Dr. Hunter utilizes a number of rodent models of stress and analyzes the impact of these stress models both on behavior and upon molecular and cellular changes in the nervous system. In particular he is interested in the changes in epigenetic marks and molecules occurring in stress sensitive brain regions such as the hippocampus. He has recently shown that one of these marks, Histone H3 lysine 9 trimethyl, a repressive mark, is involved in a genomic stabilizing response within the hippocampus that is targeted at transposable elements within the geneome. These elements, which comprise an order of magnitude larger portion of the genome than the genes themselves, are a almost completely unexplored territory with regard to brain function in health or in disease, yet they hold the promise of new understanding of the way the brain adapts, or fails to adapt, to stressful environments.
