ASSESSMENT EXAM QUESTIONS WITH
CORRECT ANSWERS (LATEST 2026 /
2027), (A+ GUARANTEE).
1. Which neurotransmitter is primarily responsible for the ‘reward’ pathway and is highly
involved in the pathophysiology of addiction and schizophrenia?
A. Serotonin
B. Gamma-aminobutyric acid (GABA)
C. Glutamate
D. Dopamine
Answer: D
Conceptual Explanation: Dopamine is the key neurotransmitter in the brain’s reward
system, particularly in the mesolimbic pathway. Dysregulation of dopamine is central to
the symptoms of schizophrenia and the mechanism of addiction.
2. The ‘low-road’ processing of emotional stimuli, which bypasses the cortex for a rapid
response to danger, primarily involves which brain structure?
A. Hippocampus
,B. Thalamus
C. Prefrontal Cortex
D. Amygdala
Answer: D
Conceptual Explanation: The amygdala processes emotional stimuli rapidly via a ‘low-
road’ shortcut from the thalamus, allowing for immediate fight-or-flight responses before
the cortex fully analyzes the threat.
3. A patient with a mutation in the MTHFR gene may have difficulty processing which
substance, potentially impacting neurotransmitter synthesis?
A. Vitamin B12
B. Iron
C. Folate (Vitamin B9)
D. Vitamin D
Answer: C
Conceptual Explanation: The MTHFR gene provides instructions for making an enzyme
that processes folate. Deficiency in this process can lead to low levels of L-methylfolate,
which is a precursor to neurotransmitters like serotonin and dopamine.
, 4. Which part of the brain is most associated with executive functions, such as decision-
making, impulse control, and personality expression?
A. Occipital Lobe
B. Cerebellum
C. Prefrontal Cortex
D. Pons
Answer: C
Conceptual Explanation: The prefrontal cortex (PFC) is responsible for higher-order
cognitive functions, including executive function, social behavior, and complex planning.
5. The theory of ‘Neuroplasticity’ suggests that the brain is capable of which of the following?
A. Remaining static after the age of 25
B. Only losing neurons over time without any growth
C. Reorganizing itself by forming new neural connections throughout life
D. Repairing damaged spinal cord nerves spontaneously
Answer: C
Conceptual Explanation: Neuroplasticity is the brain’s ability to reorganize itself by
forming new neural connections in response to learning, experience, or following injury.
