We are interested in the role of brain dopamine in learning and motivation. Dopamine activity is implicated in the reinforcing effects of cocaine, amphetamine and natural rewards like food, water and sex. Our laboratory examines the neurochemical bases of learning and motivation, particularly with respect to dopamine activity within its major brain target sites. Over the course of learning, as goal-directed behaviors become automatized habits, the neurobiological underpinnings of the behavior undergo important changes. What types of neurobiological changes occur as a goal-directed behavior becomes a habit?  What are the neurochemical events that contribute to the acquisition of habits? Some of our recent work has shown that while dopamine activity within key motivational regions - such as the nucleus accumbens - is necessary for the performance of a goal-directed behavior, dopamine involvement decreases as the behavior becomes a well-acquired habit.
