Current Research Interests

Sex Differences in Effects of Social Stress

One important feature of many mood disorders is that women are almost twice as likely as men to be affected. For a variety of reasons however, most animal models examining neurobiological mechanisms related to depression focus on males. Indeed, there is an urgent need for the development of model systems in which behaviors related to depression and anxiety can be studied in both sexes. We are studying how social stress affects behavior in male and female California mice (Peromyscus californicus). Current research projects are investigating how sex differences in neurobiological responses to stress mediate long term behavioral changes, such as social withdrawal. Diferent projects are focusing the roles of the dopaminergic, neuropeptide, neurotrophin, and endogenous opioid systems. We are using the unique biology of the California mouse to examine sex differences in neurobiological mechanisms that mediate the effects of social stress on affective behaviors.
