What percentage of the human brain is understood by researchers?

Question

I once heard it was just 10% - is this true?

Answer 1

Not true. This all started when some newspaper misquoted some researchers. Only 10% of your brain is firing at anyone time in terms of numbers and percentages of neurons firing. This number is normal and healthy. If too many neurons fire at the same time, we call that a seizure. And it would not be healthy.

As far as understood, we know pretty much what each part of our brain in responsible for. Memory, information processing and decision making are a small example of topics that still need exploring.

Answer 2

It is said that only 10% or less of the human brain is being used - but that is actually a folkloric statement. It is a misconception.Read this: http://en.wikipedia.org/wiki/Human_brain#Popular_misconceptions
I believe that researchers had struggled far to uncover to understand the human brain. Most of its part has been theoretically explained but I would say that the mystery of the brain remains. What we understood currently are just the basics of its anatomy and physiology and a fraction of its marvelous works.

Answer 3

Untrue.

We cannot know PERCENTAGE without knowing the denominator, which means we would have to know how much there IS to know, and then how much we ACTUALLY know.

Can't be done. We will never know it ALL. As soon as questions are answered, more complex questions arise.
