The Dopamine Pathway

In Unit 8 you learned about the neural control of emotion and the reward system in the brain. As part of your readings for Unit 8, you were introduced to the mesolimbic dopamine pathway and how the dopamine pathway is involved in behavioral motivation and reward. For this discussion, you will need to find an article in the library discussing the role of the dopamine pathway in the regulation of behavior. Summarize the main points from the article you find, and address the following as part of your post:

How might the dopamine pathway be implicated in behavioral problems?
What role does the dopamine pathway play in emotion?
How do you think knowledge of the dopamine pathway could be used to help someone with a problem involving compulsive behavior?
