sorts of things you should probably know 

  • Be able to explain the intracranial self-stimulation paradigm and delineate the reward pathways of the brain.
  • Be able to discuss how dopamine is implicated in drug reward and critically evaluate the empirical evidence
  • Demonstrate knowledge of acute and chronic drug effects particularly in relation to dopamine
  • Demonstrate comprehensive understanding of the various biological theories of addiction and be able to articulate their strengths and limitations

 

typical exam questions

1) Evaluate the evidence that dopamine is critical for drug reward 

2) Critically evaluate how well evidence from the study of drug effects, pleasure centres and addiction support a central role for dopamine. 

3) Discuss the role of dopamine in the neurobiology of reward and addiction.
