Research Interests:

Behavioral disorders are often pathological extensions of normal behavioral processes. Just as depression may be an inappropriate expression of grief addiction can be viewed as a corruption of motivated behaviors. The focus of this laboratory's research is the use of female sexual behavior in rodents as a model system to further our understanding of neural mechanisms of motivation, and by extension compare these mechanisms to those mediating addiction. One approach that we take is based on the observation that repeated drug use produces changes in the structure and cellular properties of dopaminergic neurons. We have found that a similar neural plasticity in dopamine pathways is seen following repeated sexual experience in female hamsters. By comparing neural changes to drugs with those resulting from engaging in natural behaviors, we can parse the neural components of drug addiction consequent to exposure to powerful pharmacological agents from the endogenous neural plasticity that underlies activities in everyday life.
