Key Points

• Wernicke vs Broca Areas
  • Wernicke’s Area
    • Located in the temporal lobe
    • Primarily functions in language comprehension
      • Wernicke’s Aphasia (receptive aphasia)
        • Individuals with damage to the Wernicke's Area can properly produce words (although the sentences will be meaningless), but they cannot understand language
  • Broca’s Area
    • Located in the frontal lobe
    • Primarily functions in language production
      • Broca’s Aphasia (expressive aphasia)
        • Individuals with damage to the Broca’s Area are unable to properly produce words, however, they can still understand the language of others
  • Arcuate Fasciculus
    • Connects Wernicke's Area and Broca's Area
    • Primarily functions in language repetition
      • Conduction Aphasia
        • Individuals with damage to the Arcuate Fasciculus have intact language comprehension and fluent speech production, but they have poor speech repetition.
  • Global Aphasia
    • Occurs when both Wernicke’s and Broca’s areas are damaged.
      • Affected individuals will have impaired language production and comprehension.
