This article just goes to show how adaptable the human body is. The featured woman was 24 years old when it was discovered she is missing her whole cerebellum and despite a few struggles with motor skills and speech, she manages just fine. It begs the question: could we survive with other parts of our brain missing? The article says it is not unheard of to be missing parts of the brain. We know that a missing cerebellum creates a few impediments, but what does a missing brain part mean for longevity, or long-term health concerns?
From my research, it appears that theoretically a person could survive without a parieto-occipital sulcus. The parieto-occipital sulcus is the ridge between the parietal lobe and the occipital lobe. person may also have a connected parietal and occipital lobe, leading to a whole new breed of problems. It appears to help with planning things - so maybe a person would struggle with forethought without it. The frontal lobe is also involved in planning, so it is possible that if the parieto-occipital sulcus was missing, the frontal lobe could just take over.
