Dr. Burghardt’s lab studies the neural circuits that underlie the cognitive impairments and emotional symptoms associated with neuropsychiatric disorders, including depression, anxiety, and eating disorders. One focus of the lab is to understand how chronic stress during adolescence leads to long-lasting changes in the neural circuits implicated in mood and anxiety disorders. A second focus of the lab is to investigate the neural pathways involved in mediating the effects of serotonin on fear learning and innate anxiety. A third aim of the lab is to identify mechanisms that increase vulnerability to anorexia nervosa, with a focus on the relationship between anorexia nervosa and dysfunction within circuits mediating fear and/or reward
