Previous articles on Unknownlist regarding the mechanics of the human brain have been more about the science behind cognitive reactions. More like the way we process information under circumstances such as addiction and rejection to mixed up memories.
Ponder this, if you will: What is it like when you’re actually missing part of your mind? Not in the sense that you went bonkers. More like you were born without part of it.
And you went to age 24 without noticing.
Thus was the case of a woman in China. She was actually lacking in one of the most important parts of the brain: The cerebellum.
Ok, so why is this so dang important? The quick and dirty version: It controls movement, such as fine motor control and balance, as well as playing a part in language comprehension and and attention span. It also contains a ton of the neurons. Think of those as runners in a relay race-neurons send information to the central nervous system. You want to throw a punch? Thank the neurons for getting that right hook just right.
Regarding the woman without her cerebellum, her brain did something remarkable: It adapted. Sure, she didn’t learn how to walk until she was seven, and had speech impairment as a child. Yet her brain compensated for it.
She is one of nine known cases of people missing cerebellum.
Back to the ‘pondering’ part at the beginning. You now know that the grey matter taking up all that space in your skull serves a purpose. And if you’re missing some, that grey matter is sometimes capable of accommodation.
TL;DTR: Just because you may have some freaky neurological abnormality, doesn’t necessarily mean you’ll notice. Know more.
