Do we need a brain? The 100gr human brain

Do you think that a person with a brain of just 100 grams (compared to the average "normal" brain of 1500 grams) could still function normally? Sounds impossible right?

Well, meet the impossible.
A normal young guy, studying mathematics and with an IQ of 126, was diagnosed with a serious form of hydrocephalus (a condition in which part of the head is filled with liquid instead of brain).
His head was 95% filled with liquid!!! Meaning that he actually had a brain of just 100 grams!!

How is this even possible? Is all we assume about the brain false? Where does our consciousness lie, where does our "thinking" really take place? Or does it mean that actually just 100 grams of brain would suffice?

The fact that such a condition is usually fatal, that people who have it often don't survive beyond childhood and that if they do they are severely handicapped makes it even more remarkable.

I am clueless!

You can read more details in this article or search the article published in Science magazine called "Is your brain really necessary?". I read about the above in "Eindeloos bewustzijn"(Endless consciousness) from cardiologist Pim van Lommel.
