"The Woman with a hole in her brain"

This article is about a 24 year old woman who had realized she was living without a cerebellum. This woman lived most of her life normally aside from her unsteady walking and her not being able to normally speak until she was 6. This article vaguely mentions that there are very little people in this world that deals with the same thing she does. The cerebellum plays a role in movement and balance which explains her difficulty to walk. Its suggested that the cortex takes the place of the missing cerebellum.
The Central sulcus is a fold in the cerebral cortex in the brain. It separates the pariental lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex. Although it is not really clear, but, I think we would not be able to live without it. It is an important part of the brain and keeps the brain funcioning in a way.
