Biobehavioral Psychology
BIO
My research interests involve understanding the neurobiological mechanisms of stress, emotion and resilience. I use a variety of techniques to investigate these mechanisms, which include assessing conditioned and unconditioned fear and anxiety, pharmacological manipulations, neuroanatomical techniques, molecular, and intracellular electrophysiological techniques. I am particularly interested in the involvement of serotonin and stress-related neuropeptides in mediating the behavioral consequences of exposure to stressful stimuli, as well as the neurochemical changes mediating stress-resilience (for example, why does exercise reduce anxiety and make you more resilient in the face of stressors). Specific questions include:
- What is the role of the bed nucleus of the stria terminalis (BNST) in mediating fear/anxiety behaviors, and how does it accomplish this role?
- How do brain areas that mediate fear/anxiety behaviors (such as the BNST) respond to serotonin, and is the response to serotonin altered by inescapable stress, chronic stress, or exercise?
- What are the roles of pituitary adenylate cyclase-activating polypeptide (PACAP) and corticotropin-releasing hormone (CRH) in mediating the behavioral and physiological consequences of stressor exposure?
- How does exercise alter brain circuits that mediate fear/anxiety behaviors?
