A Woman with a Hole in her Brian!

A Woman with a Hole in her Brian!
In the article "The Woman with a Hole in her Brain", by Helen Thomson, a woman was admitted to a hospital in the Shandong Province after experiencing nausea and dizziness. Turns out she was missing her cerebellum; this part of the brain controls the body's motion and balance. At a young age she learned to speak later than most kids, age 6, and also was a later walker than most. Considering this, her motion most likely came from the temporal lobe or the parietal lobe because they have to do with speech and language. If those two lobes took over her motion and balance then she would be slow to function and develop in both areas, speech and motion. 

Image result for hypothalamusHypothalamus: The hypothalamus is located south of the thalamus and controls the body's homeostasis (temperature, osmosis, etc). When signals are sent through the hypothalamus, the way the body keeps its homeostasis is by the secretion of hormones. I f a person were to be missing their hypothalamus, they would not grow properly, they would have hormone imbalance and they would have a hard time keeping a normal body temperature. Certain aspects of the hypothalamus can be controlled by the brain stem such as heart rate but the other aspects such as regulation of emotional hormones could be taken over by the frontal cortex and the signals for thirst or hunger could go through the somatosensory cortex in the parietal lobe of the cerebrum cortex.
