Which region is associated with repetition ability?

• A. Orbital frontal cortex
• B. Angular gyrus
• C. Arcuate fasciculus
• D. BA 39

Answer: (B)

Repetition of verbal material depends on phonological processing and short-term verbal memory within a left temporoparietal hub. The angular gyrus (BA39) sits at the junction of temporal and parietal language areas and acts as a central integrator for auditory-verbal information, linking what is heard to phonological representations that can be rehearsed and produced again. This region supports translating heard words into the articulatory plan and maintaining them in working memory long enough to repeat them. In contrast, the orbital frontal cortex is more about decision making and behavior regulation, and the arcuate fasciculus is a white matter tract connecting language regions rather than a cortical site itself. Therefore, the angular gyrus best accounts for repetition ability.
