Question

Quizplus · Accepted Answer

Broca's area, located in the left inferior frontal cortex, is responsible for speech production. Tan's difficulty generating spontaneous speech and only being able to say "tan" suggests damage to this area. The softening of tissue in the left inferior frontal cortex seen in the postmortem autopsy is consistent with this type of damage.
