How We Decide: The Neuronal Reward Signal
Using electrophysiologic measures of neuronal activity, we tested theories of reward and decision-making and have found neuronal mechanisms in circuits including dopamine neurons, the striatum, the frontal cortex, and the amygdala that reflect reward and decisions.
