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.
