Research Topics

Our lab is interested in the neural circuits mediating associative learning and decision making and how alterations in those circuits contribute to maladaptive behaviors in neuropsychiatric disorders such as addiction. We use rats as a model system to study behaviors and neural circuits that we believe have direct relevance to understanding the human brain. Areas of particular interest include the orbitofrontal cortex, amygdala, striatum, and midbrain dopamine system. Our lab uses behavioral tasks based on principles derived from learning theory, combined with single unit recording, lesions, pharmacological and genetic manipulations to test hypotheses about how these areas interact to support learning and adaptive behavior.
