Unit 3 Free Response Question Assignment

• Joe was involved in a car accident that smashed
  in the whole left side of his head.  His left ear
  is damaged completely, and he will probably lose
  vision in his left eye.  His whole right side was
  completely untouched.  He is currently in an
  induced coma, but doctors know that he will
  survive.  However, they are not able to fully
  assess what will be affected and how Joe will
  function when he awakens.  Speculate how each of
  the following aspects of the brain and nervous
  system could influence Joes recovery in the
  coming weeks and months. State how Joe will be
  affected and how he will function.
•      
• Limbic System
• Temporal Lobe
• Brocas Area
• Wernickes Area      
• Thalamus
• Cerebellum
• Primary Motor Cortex
