Biology For the Win: Woman with Half a Brain, Literally

One arm? No problem. No legs? Still Alive. One kidney? Hardly notice the difference? Half a brain? Yeah...kind of an issue there.

In Virginia lives an extraordinary woman by the name of Michelle Mack. What's so amazing about her? She has half a brain. Now all of you who have or haven't taken Biology, it usually takes one whole brain (100% physically of a brain) to survive...doesn't it? Apparently, Mack only has the right hemisphere of her brain.

Despite this "little" handicap, she still manages to do her household chores and maintain a steady job managing data for the church (I bet some full brained people can't even manage data). However, she does need some help and lives with her mom, which is granted since she is missing half of the most important organ in the body.

Now diving into the scientific aspect of this finding, Mack's right hemisphere has adapted to the situation by taking it upon itself to do some vital jobs of the left hemisphere, like speaking and reading. However, this caused the right hemisphere to lose some of its capacity as well, due to the extra jobs. Apparently, a lesion in Mack's brain at the time around her birth caused 95% of her left hemisphere to be missing.



Besides just keeping her alive, her rewiring also has allowed her to have an affinity towards remembering specific dates, which comes in handy with her church job. She specifically requested this article on CNN to be published to send out the message that she is normal. This definitely, goes under one of those inspirational stories and maybe "Ripley's Believe it or Not".
