BC Exam Study Guide
200 High-Yield Practice Questions with
Answers & Rationales (2026/2027)

DOMAIN 1: SCIENTIFIC FOUNDATIONS (Neurobiology &
Neurotransmitters)
1. Which neurotransmitter pathway is primarily responsible for the positive
symptoms of schizophrenia?
A) Mesocortical pathway
B) Mesolimbic pathway
C) Nigrostriatal pathway
D) Tuberoinfundibular pathway
Answer: B) Mesolimbic pathway
Rationale: The mesolimbic pathway projects from the ventral tegmental area to the
nucleus accumbens and limbic structures. Excess dopamine activity in this
pathway causes positive symptoms such as hallucinations and delusions. The
mesocortical pathway (low dopamine) is associated with negative symptoms, while
the nigrostriatal pathway relates to EPS when blocked.


2. Which brain region is responsible for executive functioning, judgment, and
impulse control?
A) Amygdala
B) Hippocampus
C) Prefrontal cortex
D) Basal ganglia
Answer: C) Prefrontal cortex

,Rationale: The prefrontal cortex is the "CEO" of the brain, responsible for
executive functions including working memory, planning, prioritizing, insight, and
impulse control. The amygdala processes raw emotion and fear, while the
hippocampus is involved in memory formation.


3. The primary excitatory neurotransmitter in the brain is:
A) GABA
B) Serotonin
C) Dopamine
D) Glutamate
Answer: D) Glutamate
Rationale: Glutamate is the primary excitatory neurotransmitter in the central
nervous system. GABA (gamma-aminobutyric acid) is the primary inhibitory
neurotransmitter. Serotonin and dopamine are modulatory neurotransmitters
involved in mood, reward, and various psychiatric disorders.


4. What part of the brain is responsible for the perception of pain?
A) Temporal lobe
B) Prefrontal cortex
C) Occipital lobe
D) Cerebellum
Answer: B) Prefrontal cortex
Rationale: The prefrontal cortex is involved in the cognitive and affective
processing of pain. This explains why transcranial magnetic stimulation (TMS) can
be effective for pain management. The temporal lobe processes auditory
information, and the occipital lobe processes visual information.


5. The amygdala's primary function in response to distress is to:

,A) Process visual information
B) Regulate body temperature
C) Send signals to the hypothalamus, which then communicates to the rest of the
body
D) Control voluntary movement
Answer: C) Send signals to the hypothalamus, which then communicates to
the rest of the body
Rationale: The amygdala detects threats and sends distress signals to the
hypothalamus, which then activates the sympathetic nervous system through the
autonomic nervous system, triggering the fight-or-flight response.


6. The anterior cingulate cortex is critical for which function and is implicated
in which condition?
A) Processing taste; eating disorders
B) Stress response; childhood trauma
C) Balance and coordination; cerebellar disorders
D) Sleep-wake cycles; insomnia
Answer: B) Stress response; childhood trauma
Rationale: The anterior cingulate cortex is critical for the stress response and has
been implicated in the neurobiological effects of childhood trauma. It plays a role
in emotional regulation and conflict monitoring.


7. Extrapyramidal symptoms (EPS) are caused by dopamine blockade in
which pathway?
A) Mesolimbic pathway
B) Mesocortical pathway
C) Nigrostriatal pathway
D) Tuberoinfundibular pathway
Answer: C) Nigrostriatal pathway

, Rationale: The nigrostriatal pathway projects from the substantia nigra to the
k k k k k k k k k k




striatum. Blockade of dopamine in this pathway leads to movement disorders
k k k k k k k k k k k




including dystonia, parkinsonism, and akathisia. This pathway is most affected by
k k k k k k k k k k k




typical antipsychotics.

8. The dorsolateral prefrontal cortex is responsible for:
k k k k k k




A) Emotional regulation k




B) Executive functioning k




C) Visual processing k




D) Hearing and language k k




Answer: B) Executive functioning
k k k




Rationale: The dorsolateral prefrontal cortex is responsible for executive functioning.
k k k k k k k k k




It undergoes maturation until early adulthood, which explains why impulse control

and planning abilities develop progressively through adolescence.

9. The orbitofrontal cortex controls which functions?
k k k k k




A) Visual processing and color perception
k k k k




B) Impulses and attention k k




C) Language comprehension k




D) Motor coordination k




Answer: B) Impulses and attention
k k k k




Rationale: The orbitofrontal cortex is the region of the brain that controls impulses and
k k k k k k k k k k k k k




attention. This area is implicated in ADHD pathophysiology and impulse control
k k k k k k k k k k k




disorders.

10. Issues with which lobe can lead to visual or auditory hallucinations?
k k k k k k k k k k




A) Frontal lobe k




B) Parietal lobe k
