The brain is the human body's most mysterious organ. 

It learns. It changes. It adapts.

 It tells us what we see, what we hear. It lets us feel love. 

Maybe it holds our soul. 

But no matter how much research we do, no one can really say how all the delicate gray matter inside our skull works. 

And when it's hurt, when the human brain is traumatized, well, that's when it gets even more mysterious.
