Dr. Fadok’s research is focused on understanding how the brain controls the formation and expression of emotional memory at the level of defined neuronal circuits. He is currently interested in understanding how brain-wide neuronal networks interact to influence learning and adaptive behavior. Work in his laboratory involves using cutting-edge methodology such as large-scale in vivo recordings of neuronal activity, targeted manipulations of function in behaving animals, as well as cell-type specific neuroanatomical tracing techniques.
