Dr. Kravitz is an Investigator in the Eating and Addiction Section, Diabetes, Endocrinology, and Obesity Branch of the National Institute of Diabetes and Digestive and Kidney Diseases. His work focuses on the study of basal ganglia circuits and how their function changes in disease states such as obesity, addiction, and depression. Under normal conditions, the basal ganglia drives animals toward the selection of specific behavioral outcomes. Learning can bias this selection process toward specific behavior by altering synapses within and outside the basal ganglia. In extreme cases, these synaptic alterations can produce pathological behavioral selection, as in obesity or addiction. Using behavioral testing, optogenetics, and in vivo electrophysiology and optical measurements, the lab characterizes changes in behavior following learning in a feeding context and attempts to understand the neural correlates and causes of these changes in behavior.
