21. 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 Joe’s recovery in the coming weeks and months. State how Joe will be affected and how he will function.
     
Limbic System
Temporal Lobe
Broca’s Area
Wernicke’s Area
