Final answer:
Damage to Broca's area or Wernicke's area can result in different types of aphasia that affect speech production or understanding of content.
Step-by-step explanation:
Aphasia, or loss of language and speech functions, can occur as a result of a stroke in certain brain areas related to language. In particular, damage to Broca's area or Wernicke's area can lead to different types of aphasia. Broca's area, located in the frontal lobe, is associated with expressive aphasia, which affects speech production. Wernicke's area, located near the auditory association cortex, is associated with receptive aphasia, which affects the understanding of content.
