Aphasia - Coggle Diagram

- - - - Broca's area intact but connection cut to frontal lobe
      - Repetition ability remains intact
      - Language motor functions impaired
    - - production compromised
      - Comprehension preserved
      - Damage to posterior left inferior frontal gyrus
        Frontal Lobe
  - - - Theorized by connectionist model
      - Damage to arcuate fasciculus (white matter connection between Broca's and Wernicke's areas
      - Very rare
      - Difficulty generating and repeating speech (paraphasic), normal comprehension
    - - Repetition ability remains intact
      - Wernicke's area intact but connection cut from angular gyrus (association complex)
      - Paraphasia
        
        word substitution ex. I slipped on lice
    - - Comprehension compromised
      - Production preserved
      - Damage to posterior left superior temporal gyrus
        Temporal Lobe
    - - Damage to ventral temporal lobe (object identification)
      - extensive/persistent lack of ability to name objects
- - - - Thalamus-Primary auditory complex connection
      - Right-Left Hemisphere connection (Corpus Callosum)
