A patient visits a neurologist and complains of memory problems, such as trouble remembering telephone numbers. After a few tests, the neurologist determines that there is a large impairment in the digit span, but no impairment in remembering the past or in forming new memories. Which brain area is the most likely to be impaired?
A)the left medial temporal lobe
B)the right medial temporal lobe
C)the left perisylvian cortex
D)the right perisylvian cortex

Question

Quizplus · Accepted Answer

The left perisylvian cortex is involved in language and working memory processes, including the manipulation and temporary storage of verbal information such as telephone numbers. Impairment in digit span, which is a measure of working memory capacity for numbers, would likely be associated with dysfunction in this area, rather than areas more closely associated with long-term memory or spatial processing.
