Answer to Question 1

Answer: 4
Explanation: Norepinephrine is an exciting neurotransmitter involved in the fight or flight response. Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that is calming, quieting, and relaxing. Serotonin is a modulating neurotransmitter involved in impulse control, mood, and affect. Dopamine is a modulating neurotransmitter involved in reward seeking behavior.

Answer to Question 2

Answer: 1
Explanation: A PET scan provides information about the metabolic functioning of the brain. CT, MRI, and SPECT are imaging techniques to examine the structure, not function, of the brain.
