L1.2.1.1.1.3: Specialized Areas of Cerebral Cortex

• SPECIALIZED AREAS OF CEREBRAL CORTEX

  ● BROCA’S AREA — motor speech area

  ● ANTERIOR ASSOCIATION AREA — prefrontal cortex

  ● POSTERIOR ASSOCIATION AREA

  ● WERNICKE’S AREA
• ● BROCA’S AREA — motor speech area

  ○ Function:

  ■ Helps us speak by sending the motor signals that allow us to form words without our mouths

  ■ Speech production and articulation
• ● BROCA’S AREA — motor speech area

  ○ Location:

  ■ Precentral gyrus; based of the frontal lobe
• ● BROCA’S AREA — motor speech area

  ○ Motor Aphasia (Expressive)

  ■ Damage to broca’s area, usually the left

  ■ You know what to say but can’t vocalize the words
• ● ANTERIOR ASSOCIATION AREA — prefrontal cortex

  ○ Function:

  ■ Higher intellectual reasoning

  ■ Socially acceptable behavior

  ■ Stores complex memories in the temporal and frontal lobes
• ● ANTERIOR ASSOCIATION AREA — prefrontal cortex

  ○ Location:

  ■ Anterior frontal lobe
• ● POSTERIOR ASSOCIATION AREA

  ○ Function:

  ■ Recognizes patterns and faces

  ■ Blends several inputs into an understanding of the whole situation
• ● POSTERIOR ASSOCIATION AREA

  ○ Location:

  ■ Posterior cortex
• ● WERNICKE’S AREA

  ○ Function:

  ■ Language processing (can be written or spoken)

  ■ Helps in comprehension

  ■ General interpretation area
• ● WERNICKE’S AREA

  ○ Location:

  ■ Within the posterior association area
• ● WERNICKE’S AREA

  ○ Sensory Aphasia (Receptive)

  ■ Difficulty to understand language

  ■ Can speak long sentences but have no meaning
