From actions to habits: neuroadaptations leading to dependence.

Alcohol Research & Health | December 22, 2008| | Copyright

Addiction is a series of misguided actions. Yet how the brain selects and generates actions has received surprisingly little attention in addiction research. In recent years, considerable progress has been made in identifying the neural circuits responsible for the control of goal-directed actions and habit formation. It is becoming increasingly clear that drugs of abuse can alter these neural pathways. This article discusses the mechanisms underlying reward-guided action selection and their implications for research on alcohol addiction.
