In the first study of its kind, researchers at Massachusetts General Hospital identified a mechanism for the anorexigenic effect of oxytocin. It attenuates functional connectivity between the ventral tegmental area and other brain regions involved in processing visual food cues.

Dr. Lawson is a clinical researcher who studies the role of the hormone oxytocin in a range of disorders, including hypopituitarism, eating disorders, obesity, and osteopenia/osteoporosis. Her research also focuses on endocrine regulation of eating behavior and metabolism in eating disorders and obesity.
