Reward system

Index Reward system

The reward system is a group of neural structures responsible for incentive salience (i.e., motivation and "wanting", desire, or craving for a reward), associative learning (primarily positive reinforcement and classical conditioning), and positive emotions, particularly ones which involve pleasure as a core component (e.g., joy, euphoria and ecstasy).
