# NR546 Midterm Exam 2026/2027 –
Advanced Psychopharmacology and
Neurobiology
### NEUROANATOMY AND BRAIN STRUCTURE QUESTIONS
**1. How does the orbitofrontal cortex (OFC) affect the amygdala?**
A) Only inhibits the amygdala
B) Only activates the amygdala
C) Inhibits and activates the amygdala
D) Has no effect on the amygdala
💫ANSWER✔️✔️: C
💫RATIONALE✔️✔️: The orbitofrontal cortex (OFC) provides top-down regulation of emotional
responses through its dual effect on the amygdala—it both inhibits and activates this structure. This
regulatory function is essential for emotional control and is a key consideration in psychopharmacology
for mood disorders .
**2. Wernicke's area is associated with which of the following?**
A) Speech production
B) Speech comprehension
,C) Motor coordination
D) Visual processing
💫ANSWER✔️✔️: B
💫RATIONALE✔️✔️: Wernicke's area, located in the temporal lobe, is responsible for speech
comprehension. Damage to this area results in receptive aphasia, where the patient can produce speech
but cannot understand language .
**3. The limbic system is associated with which of the following?**
A) Motor coordination
B) Speech production
C) Emotion and learning
D) Visual processing
💫ANSWER✔️✔️: C
💫RATIONALE✔️✔️: The limbic system is the brain's emotional and memory center. It includes
structures such as the amygdala, hippocampus, and nucleus accumbens, and is involved in pleasure,
reward, and reinforcing behavior .
**4. Which brain structure is most associated with long-term memory?**
A) Amygdala
B) Thalamus
C) Hippocampus
D) Basal ganglia
💫ANSWER✔️✔️: C
, 💫RATIONALE✔️✔️: The hippocampus, located deep in the temporal lobes, is involved in anxiety,
memory, and shifting short-term to long-term memory. Hippocampal function is impaired in
schizophrenia and dementia .
**5. Which brain structure is involved in the reward circuit and reinforces addictive behaviors?**
A) Dorsal striatum
B) Nucleus accumbens
C) Thalamus
D) Corpus callosum
💫ANSWER✔️✔️: B
💫RATIONALE✔️✔️: The nucleus accumbens is a key structure in the reward circuit. Drug abuse
affects the limbic system, disrupting emotions and feelings associated with normal behavior. The
nucleus accumbens reinforces addictive behaviors .
**6. Which structure controls communication between the two brain hemispheres?**
A) Central sulcus
B) Thalamus
C) Corpus callosum
D) Basal ganglia
💫ANSWER✔️✔️: C
💫RATIONALE✔️✔️: The corpus callosum controls communication between the two brain
hemispheres. It is involved in attention, impulse control, and emotion regulation, integrating impulses
from both sides of the brain .
**7. The mesolimbic dopamine pathway is associated with which of the following?**
