Dr. Northcutt’s main research interests are the neurobiology and neuroendocrinology of social behavior. She is particularly interested in neurochemical systems that influence the social interactions of juveniles (particularly play behavior in rats), and the ways that these systems change throughout adolescence, resulting in a decrease in affiliative behavior in adults. In addition, there are marked sex differences in the degree to which play occurs in some rat strains, and Dr. Northcutt is also exploring the neural underpinnings of these sex differences. Finally, she is interested in how hormones, including estrogens, androgens, and thyroid hormones, affect the development of typical social behavior.
