A woman, at the not-so-young age of 24, had gone to the "Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province" feeling dizzy and nauseated. No small wonder, as the doctors found out, because she was missing a very, er, central portion of her brain: a cerebellum. The cerebellum, though consisting of about a mere 10% of the brain's total volume, consists of around half of the brain's total neurons. Since it controls the motor functions and stores some muscle memory, there were a few- now explained- complications during her childhood, like trouble speaking or walking.

What if you were missing... an occipital lobe?
Since the occipital lobe processes information from the eyes, without one, there would be no way to fully sort, process, and utilize the immense visual information constantly streaming from the eyes, thus, blindness or heavily impaired vision would not be outside the realm of possibility.
