Nocturnal restlessness behavior, known as Zugunruhe, is demonstrated by caged birds during the migratory period. The cause of these seasonal changes in behavior and physiology are still unknown, however recent studies in our lab indicate a role for adiponectin in regulating some aspects of these changes. Using immunohistochemistry, I am examining the location and abundance of receptors for adiponectin in order to better understand the neuronal mechanisms involved in the seasonal appearance of Zugunruhe.
