SECTION 1: NEUROBIOLOGY & NEUROTRANSMISSION
1. Which neurotransmitter is most commonly associated with the pathophysiology of
depression?
A) Dopamine
B) Serotonin
C) Acetylcholine
,D) Glutamate
Correct Answer: B. Serotonin
Rationale: Serotonin (5-HT) is strongly implicated in depression, and most
antidepressants target serotonergic systems.
2. Which neurotransmitter is primarily associated with schizophrenia?
A) Serotonin
B) Dopamine
C) GABA
D) Norepinephrine
Correct Answer: B. Dopamine
Rationale: The dopamine hypothesis of schizophrenia suggests that excessive
dopaminergic activity in mesolimbic pathways contributes to positive symptoms.
3. Which neurotransmitter is the primary inhibitory neurotransmitter in the central
nervous system?
A) Glutamate
B) GABA
C) Dopamine
D) Serotonin
Correct Answer: B. GABA
,Rationale: GABA (gamma-aminobutyric acid) is the major inhibitory neurotransmitter
in the CNS, reducing neuronal excitability.
4. Which neurotransmitter is the primary excitatory neurotransmitter in the CNS?
A) GABA
B) Glutamate
C) Serotonin
D) Dopamine
Correct Answer: B. Glutamate
Rationale: Glutamate is the primary excitatory neurotransmitter, involved in
learning, memory, and synaptic plasticity.
5. Which receptor type is most associated with the mechanism of action of
benzodiazepines?
A) Serotonin 5-HT2A
B) Dopamine D2
C) GABA-A
D) NMDA
Correct Answer: C. GABA-A
Rationale: Benzodiazepines bind to the GABA-A receptor, enhancing the inhibitory
effects of GABA.
, 6. Which enzyme is responsible for the breakdown of dopamine, norepinephrine,
and serotonin?
A) Acetylcholinesterase
B) Monoamine oxidase (MAO)
C) Catechol-O-methyltransferase (COMT)
D) Both B and C
Correct Answer: D. Both B and C
Rationale: MAO and COMT are both enzymes involved in the breakdown of
monoamine neurotransmitters.
7. What is the primary mechanism of action of selective serotonin reuptake
inhibitors (SSRIs)?
A) Blockade of serotonin receptors
B) Inhibition of serotonin reuptake
C) Stimulation of serotonin release
D) Inhibition of MAO
Correct Answer: B. Inhibition of serotonin reuptake
Rationale: SSRIs block the serotonin transporter (SERT), increasing synaptic serotonin
levels.
8. Which brain region is most associated with the reward pathway and is involved
in substance use disorders?
A) Prefrontal cortex
