ABCN ABCN Brain-Behavior Relationships and Neuroanatomy 1 — Questions and Answers
Question 1: Which lobe of the brain is primarily associated with executive functions such as planning, working memory, and inhibition?
- Frontal lobe (Correct answer)
- Parietal lobe
- Temporal lobe
- Occipital lobe
Correct answer: Frontal lobe
The prefrontal cortex within the frontal lobe is the primary substrate for executive functions including planning, inhibitory control, and working memory.
Question 2: Broca's area, critical for expressive language production, is located in the:
- Left inferior frontal gyrus (Correct answer)
- Left superior temporal gyrus
- Right parietal lobe
- Anterior cingulate cortex
Correct answer: Left inferior frontal gyrus
Broca's area resides in the left inferior frontal gyrus (pars triangularis and pars opercularis) and is essential for speech production and language formulation.
Question 3: A patient presents with severe anterograde amnesia following a bilateral surgical resection. Which structure was most likely damaged?
- Hippocampus (Correct answer)
- Amygdala
- Thalamus
- Caudate nucleus
Correct answer: Hippocampus
Bilateral hippocampal damage is the classic cause of severe anterograde amnesia, as illustrated by the famous patient H.M.
Question 4: Which neuropsychological syndrome is characterized by inability to recognize familiar faces despite intact visual acuity?
- Prosopagnosia (Correct answer)
- Simultanagnosia
- Anosognosia
- Alexia without agraphia
Correct answer: Prosopagnosia
Prosopagnosia is the selective inability to recognize familiar faces and is typically associated with bilateral or right fusiform gyrus lesions.
Question 5: Damage to the right parietal lobe is most commonly associated with which neuropsychological deficit?
- Hemispatial neglect of the left visual field (Correct answer)
- Broca's aphasia
- Anterograde amnesia
- Prosopagnosia
Correct answer: Hemispatial neglect of the left visual field
Right parietal lobe lesions classically produce left hemispatial neglect, where patients fail to attend to stimuli in the contralesional left visual field.
Question 6: The dorsolateral prefrontal cortex (DLPFC) is most closely associated with which cognitive function?
- Working memory and cognitive flexibility (Correct answer)
- Emotional regulation and fear conditioning
- Primary sensory processing
- Procedural motor learning
Correct answer: Working memory and cognitive flexibility
The DLPFC is a key substrate for working memory, cognitive flexibility, and goal-directed behavior within the executive function network.
