Biosketch

Jeff Wickens leads the Neurobiology Research Unit. The unit's research concerns the neural mechanisms underlying learning and adaptive behavior in the mammalian brain, and uses a combination of experimental and computational approaches focused on the striatum of the basal ganglia and the neuromodulators, dopamine and acetylcholine, that play a central role in the cellular mechanisms of reinforcement.
