RESEARCH

Dr. David Morilak’s research addresses the neurobiology of stress and its negative impact on health and brain function. He studies how the brain adapts to effectively cope with stress; how chronic stress can lead to serious psychiatric disorders, including depression, PTSD and other illnesses; and his laboratory investigates new and more effective therapeutic strategies for the treatment of such disorders. Approaches span the molecular to the behavioral, incorporating measures of gene and protein expression, receptor function and signal transduction, neurotransmitter release, and behavioral assays for anxiety, coping strategies, cognitive flexibility and stress reactivity in rats. Techniques include rtPCR, western blot, cell culture, in situ hybridization, immunocytochemistry, microdialysis, stereotaxic surgery, intracerebral and systemic drug administration and behavioral pharmacology. His work is funded by grants from the NIH, DoD, VA, and the pharmaceutical industry.
