A 24- year old woman went to a hospital in China complaining of nausea and dizziness. She also has had problems with walking steadily and was a slow developer as a child. After a CAT scan, doctors found that the woman was missing her cerebellum, a region underneath the two hemispheres that makes up 10% of the brain. The cerebellum is known as the "little brain" as it contains a different structure, made up of denser folds and contains 50% of the brain's neurons. Most people die with such a condition and normally suffer from conditions like severe mental impairment, movement disorder, epilepsy, or buildup of fluid.
On a similar topic, if one was missing or damaged their occipital lobe, he/ she would probably live. They, however, would possibly have symptoms like loss of some/all vision, inability to identify colors, or hallucinations (brainandspinalcord.org). Since damage to the occipital lobe affects the vision, the body would lose visual function and perception, and therefore would need to compensate. In an effort to rebalance the body, the other sense would have to work more. The brain does this by sending the signals from the occipital lobe to other parts of the brain such as the temporal lobe, which processes sound (NCBI).
