SECTION 1: FOUNDATIONS OF PSYCHOPHARMACOLOGY &
NEUROANATOMY (15 Questions)
Q1: What area of the brain is most associated with cognitive symptoms (executive
dysfunction, working memory deficits) in psychiatric disorders?
A. Orbitofrontal cortex
B. Dorsolateral prefrontal cortex [CORRECT]
C. Amygdala
D. Hippocampus
Correct Answer: B
Rationale: The dorsolateral prefrontal cortex (DLPFC) is critical for executive functions
including working memory, abstract thinking, cognitive flexibility, and decision-making.
Dysfunction here produces cognitive symptoms seen in schizophrenia, depression, and
,ADHD. The orbitofrontal cortex (A) regulates emotional impulses; amygdala (C)
processes fear; hippocampus (D) consolidates memory.
Q2: A patient presents with aggressive outbursts, impulsivity, and poor emotional
regulation following traumatic brain injury. Which brain area and connection is most
likely affected?
A. Occipital lobe and visual cortex
B. Orbitofrontal cortex and its connections to the amygdala [CORRECT]
C. Parietal lobe and somatosensory cortex
D. Cerebellum and motor coordination centers
Correct Answer: B
Rationale: The orbitofrontal cortex and its connections to the amygdala regulate
emotional impulses and aggression. Damage here disinhibits aggressive responses and
impairs social judgment (Phineas Gage classic case). The occipital lobe (A) processes
vision; parietal lobe (C) processes sensory information; cerebellum (D) coordinates
movement.
Q3: Damage to the parietal lobe, particularly the anterior portion, may result in:
A. Visual hallucinations
B. Astereogenesis (inability to recognize objects by touch) [CORRECT]
C. Personality changes and emotional dyscontrol
D. Impaired short-term memory conversion
Correct Answer: B
Rationale: The parietal lobe processes sensory information including touch, pain,
temperature, and spatial relationships. Anterior parietal damage can cause
,astereogenesis—inability to recognize objects through touch alone—sometimes seen
after cerebrovascular accidents. This demonstrates the parietal lobe's role in
somatosensory integration.
Q4: A patient has difficulty recognizing faces (prosopagnosia) despite intact visual
acuity. Which lobe is most likely affected?
A. Frontal lobe
B. Temporal lobe
C. Occipital lobe [CORRECT]
D. Parietal lobe
Correct Answer: C
Rationale: The occipital lobe contains primary and association visual cortex. Bilateral
damage to visual association areas can cause visual agnosia—inability to recognize
items by sight despite intact vision. The fusiform gyrus (temporal-occipital junction)
specifically processes faces. This illustrates hierarchical visual processing.
Q5: The structure that connects the two cerebral hemispheres and facilitates
interhemispheric communication is the:
A. Thalamus
B. Corpus callosum [CORRECT]
C. Basal ganglia
D. Central sulcus
Correct Answer: B
Rationale: The corpus callosum is the largest white matter tract, containing over 200
million axons connecting homologous areas of left and right hemispheres. It integrates
, motor, sensory, and cognitive functions across hemispheres. Damage causes
"split-brain" syndrome. The thalamus (A) relays sensory information; basal ganglia (C)
control movement; central sulcus (D) separates frontal from parietal lobes.
Q6: The hippocampus, located deep in the temporal lobes, is primarily involved in:
A. Motor coordination and balance
B. Anxiety responses, memory formation, and converting short-term to long-term
memory [CORRECT]
C. Visual processing and object recognition
D. Regulation of hunger and body temperature
Correct Answer: B
Rationale: The hippocampus is critical for declarative memory formation, spatial
navigation, and emotional regulation (via connections to amygdala and HPA axis). It
converts short-term to long-term memory and is vulnerable to stress (cortisol),
explaining hippocampal volume reduction in depression and PTSD. This supports the
neurotrophic hypothesis of depression.
Q7: All olfactory signals travel directly to which structure, bypassing the thalamus,
making smells powerful emotional triggers?
A. Thalamus
B. Amygdala [CORRECT]
C. Hypothalamus
D. Basal ganglia
Correct Answer: B
