Are we relly using the human brain to only 4%

Hmm, I'd like to see more research being done though.
Surely we can't know for certain?

Yes we can. Researchers pop their test subjects in an MRI machine and give them various tasks to do. They can watch the various parts of the brain 'light up like a Christmas tree'. Some tasks require more brain activity than others, and no part of the brain is unused.
The whole thing simply is not open to question. There are many interesting questions about brain activity still to be answered, but how much of the brain is used is not one of them.

go to Best Buy and purchase a dvd called
1. "what the bleep" "down the rabbit hole"
2. it will change your life
3. and it might also stop people like kmguru from being so defensive to information he or she does not understand.

A: just a few quick comments

1. my cousin bought it, we watch it, what a waste, its a mixed bag of science, pseudo-science & new age, nice graphics :)
2. its some kind of new age cult that did this, its not science but uses science as a prop, to lend credibility to itself
3. all information is good to know, but how or why you use it is the difference, K seems to be on the right track, while you are off-track

There is a woman called Sharon Parker who was born with hydrocephalus.

So, we can definitely function without 85% to 90% of our brains.
Sharon is proof of that.[/url]

No she isn't. Read the whole article...

For Sharon, the most important discovery the American doctors made concerned the size of her brain. Something that only the very latest technology allowed them to measure. Having been told, all her life, that she has only 10-15% of a normal brain the result came as a welcome surprise, but it was something of a shock for Dave. While the volume of Dave's brain was 1300cc Sharon took great delight in telling him that hers was 2300cc.

The American doctors had discovered that although Sharon's ventricles expanded hugely because of her hydrocephalus, it was not at the expense of brain size. Part of the brain mass was pushed to the bottom rear of her skull and because her infant head swelled slightly her brain is actually occupying a larger space.

They're seeing things that "aren't there" but how do we know that the things that they're seeing aren't actually there?

Actually they usually are just seeing echos and distortions, as opposed to seeing things which "aren't there." Despite the name, it takes a pretty stiff dose to actually see full on hullucinations. Other substances, or means, can more readily produce hullicinations, tropanes (warning - unlike acid, tropane overdoses can easily become fatal), sleep deprivation, sensory deprevation, hypnosis, etc.

Maybe they are there, we just can't see them because the amount of brain power we're using isn't strong enough to let us see those things.

Something which one person only can see, which has no physical presence detectible by any one else, is "there" only in their mind.

You may have a point there, but since our scientists do not research these stuff for the fear of being ridiculed, we will never know.

Actually they did quite a bit of research until the government shut them down. Quite a number of very promising treatments for a number of difficult problems were cut off.

There is still a dedicated group of scientists working with these substances, some interesting results recently for cluster headaches and mushrooms, MDMA and PTSD, MDMA and terminal illness, mushrooms and DMT and religious responses, and ibogain and opiate addiction.

50% of the brain is used to process information from the eye. Think about it, space...depth...color...movement...threats. Think about the process of driving a car or riding a bicycle down a busy road. Or better, looking for threats to your life while hunting for food. Processing the information, reaction and decision making takes a lot of computing power.
 
Actually, I believe that even if there was a way of how to use the full capacity of our brain it wouldn't do us good. It would be like overheating a motor, and that doesn't seem quite good now does it?

Also, I don't think that it is possible to use 100% of the brain at once as there is no task, at least not known to me, that would need the full potential of our brain...mmh maybe multi-tasking, but even then....
