  • Schizophrenia is produced by a single dominant gene

Question 5

Question
Imagine that you have been handed a list of drugs and that beside each drug name is a number that represents the potency of that drug for blocking midbrain dopamine receptors (where a low number means a greater potency at blocking). Which would you choose for the treatment of schizophrenia?
Answer
  • Potency value = 0.1
  • Potency value = 0.3
  • Potency value = 1.0
  • Potency value = 5.0

Question
Administration of high doses of which of the following drugs would be expected to produce the positive symptoms of schizophrenia:
