Others encode motivational salience, supporting brain networks for orienting, cognition, and general motivation. Some dopamine neurons encode motivational value, supporting brain networks for seeking, evaluation, and value learning. Based on this data, we propose that dopamine neurons come in multiple types that are connected with distinct brain networks and have distinct roles in motivational control. Here we review recent advances in understanding the reward and nonreward functions of dopamine. It has become increasingly clear, however, that dopamine neurons also transmit signals related to salient but nonrewarding experiences such as aversive and alerting events. Midbrain dopamine neurons are well known for their strong responses to rewards and their critical role in positive motivation. ![]()
