Dopamine and Drug addiction:
Part 1. Describe the mechanism of action for Dopamine (DA) agonist drugs (e.g., L-Dopa, cocaine) and describe the hypothesized role of DA release in the reinforcing effects of psychostimulants.
Part 2. The research on sensitization of the nucleus accumbens has dealt with addictive drugs, mainly cocaine. Would you expect a gambling addiction to have similar effects? How could someone test this possibility?
