Rewarding Dopamine Wolfram Schultz University of Cambridge, United Kingdom
Dr. Schultz will discuss the behavioral functions of explicit dopamine signals which concern primarily reward value and risk and, to a much lesser extent, punishment and physical salience. In coding reward information, the dopamine neurons are a component of the brain’s reward system, which includes also the striatum, orbitofrontal cortex and amygdala, whose functions will be briefly mentioned. Despite the well characterized role in reward, the overall functions of the dopamine system extend beyond reward and include a permissive role in a large number of movement and cognitive processes which are deficient in diseases such as Parkinson’s.
