Question: Brodmann's areas are differentiated by the:
A) Cellular architecture
B) Vascular supply
C) Functional connectivity
D) Neurotransmitter density
Correct Answer: A Cellular architecture
Expert Rationale: Brodmann's areas are defined by their distinct cytoarchitecture (cellular
structure and organization). Understanding this is essential because Brodmann's map
divides the cerebral cortex into 52 areas based on cell density, layer thickness, and cellular
morphology. These areas correlate with different functions.
Question: The orbitofrontal aspect of the PFC describes the area:
A) At the top of the PFC
B) At the base of the PFC
C) In the middle of the PFC
D) At the back of the PFC
Correct Answer: B At the base of the PFC
Expert Rationale: The orbitofrontal cortex is located at the base of the prefrontal cortex,
just above the orbits (eye sockets). Understanding this is essential because the
orbitofrontal cortex is involved in decision-making, reward processing, and impulse
control. Damage to this area can result in disinhibition and poor judgment.
Question: Lesions of the medial (also ventromedial) PFC are associated with:
