• Broca area in inferior frontal gyrus of frontal lobe. Associated with defective language production, aka expressive aphasia. Patients appear frustrated, insight intact.

Mnemonic

Think of a pull string doll that will talk when you pull on its string. If this becomes Broca (broken), then the doll won’t talk.

• Wernicke area in superior temporal gyrus of temporal lobe. Associated with impaired language comprehension. Patients do not have insight.

Mnemonic

Someone with Wernicke’s aphasia can still be quite Wer-dy.

• The arcuate fasciculus connects Wernicke’s area to Broca’s area. Damage to the arcuate fasciculus results in a conduction aphasia.

Mnemonic

Without an accurate fasciculus, you cannot accurately repeat what someone just said.

• Global aphasia: Broca and Wernicke areas affected.
