This review highlights the critical role of the dopaminergic system in reward processing and human behavior. Neuroimaging studies now allow exploration of neuronal circuits underlying emotions, drive, and motivation.

Area of Science:

  • Neuroscience
  • Neurobiology
  • Behavioral Science

Background:

  • Animal studies on reward processing have advanced, enabling translation to human in vivo research.
  • The dopaminergic system is fundamental to reward mechanisms.
  • Understanding the neural basis of human behavior requires examining reward circuitry.

Purpose of the Study:

  • To review concepts of reward processing.
  • To summarize the importance of the dopaminergic system.
  • To discuss human neuroimaging studies on reward and behavior.

Main Methods:

  • Review of existing literature.
  • Analysis of neuroimaging studies in humans.
  • Conceptual definition of reward-related behaviors.

Main Results:

  • The dopaminergic system is crucial for organizing motor and motivational systems.
  • Abstract human behaviors like emotions and drive are linked to neuronal circuit organization.
  • Neuroimaging facilitates in vivo study of reward processing in humans.

Conclusions:

  • The dopaminergic system is central to reward, motivation, and motor control.
  • Human neuroimaging offers new avenues to study the neural basis of complex behaviors.
  • Further research can elucidate the neuronal circuitry of reward in humans.
