Answer to Question 1

Answer: Answers will vary depending on chosen drugs. Agonists should clearly demonstrate an increase in neurotransmitter action, whereas antagonists should clearly indicate a decrease in neurotransmitter action.

Answer to Question 2

Answer: This would involve the student reproducing Figure 4.7a on page 98.
Possible answers include:
Blockade of synthesis (administration of a drug that inhibits an enzyme required for synthesis.
Administration of a drug such as reserpine that inhibits storage within the vesicles.
Administration of a drug that blocks release of the transmitter (or induces release).
Administration of a drug that binds to and activates the postsynaptic receptors.
Administration of a drug that blocks reuptake of the transmitter.
