Emotion, Motivation, Reward, and Addiction

Emotion, Motivation, Reward, and Addiction

The study of the neural systems that underlie emotion, motivation and reward, with particular focus on circuit level interactions between these systems. Research is focused on understanding the mechanisms that drive behavior, and how these systems explain the process of addiction.
