Woman of 24 found to have no cerebellum in her brain
This also reminds me of Hemispherectomy[0] where an entire half of the brain is surgically removed in extreme cases to prevent seizures. And amazingly, especially if you do this on younger children:<p>"Studies have found no significant long-term effects on memory, personality, or humor,[4] and minimal changes in cognitive function overall."<p>If you don't _really_ need half of the brain and you don't _really_ need the cerebellum, I wonder how little (and what part) of the brain we actually do _really_ need. And then there are so many people living just fine with lesions in so many parts of the brain.<p>It's just amazing. Imagine going into our code bases and tearing out entire classes or modules; That wouldn't go down well.<p>[0] <a href="http://en.wikipedia.org/wiki/Hemispherectomy" rel="nofollow">http://en.wikipedia.org/wiki/Hemispherectomy</a>
