"The Woman With a Hole in Her Brain"

This article talks about a woman that basically had lived during 24 years with our Cerebellum, organ that have 50 % of the total of nerves of the brain. She started talking when she was 6 years and to walk when she was 7. The doctors where impressed because the other cases that were know were discovered in the autopsy, this people die when they are so young. Related to the subject of Anatomy & Physiology we can learn that the Cerebellum is responsible of the body control, voluntary movements and balance. But this girl talked and walked, the doctor said that the explanation for that was that maybe the cerebral cortex have been taken over this.

Midbrain: Imagine that a person have missed or severely damaged this structure, what would they not be able to do? Could they survive without it? Could other parts of the brain take over? 
The Midbrain is responsible for transfer visual & auditory input to the brain and motor information from the brain. It is located in the brainstem, between forebrain and hindbrain. 
So basically any person would not be able to see or move if no-one of the other structures could helping the transfer of the information. I think that they could survive but with all their lives without moving. Maybe other parts of the brain could help like the ones that are involved in processing information.
