why is it that we only use a small percetage of our brain?

Question

what keeps us from using entire brain?

Answer 1

I don't believe this tale anymore. I've seen the real-time PET scans of the brain when people are asked series of questions and shown images and activity is shown all over the place.
Also, during brain surgery, folks are sometimes kept awake to avoid damaging critical functions, active areas are so close together. (The brain itself doesn't have nerves that cause pain during surgery.) Just because they can remove portions and the people are okay, it doesn't necessarily mean the areas did nothing, so much as the brain can rewire itself to some extent.
Nature isn't known for being wasteful, either. I don't think women would have to pass these big heads through the birth canal that are only designed to hold a bunch of mostly useless gray matter. Not buying it...
It tells me that our understanding of the brain leaves much to be desired still.

Answer 2

By spelling "percetage" itself its clear that you don't use the brain properly. Brain is not something where you can go in and make its full use. In the human body, every organ is made with lots of spare capacity( sometimes more than you can imagine) and that's why our abuse of the organs are never noticed as diseases!! Similarly. the almighty knows that there are millions of uses for the brain and does not want the man's hard disk to go out of space. Defragging is done everyday to keep the information organized and its a never ending process. There is no rest for the brain throughout life and thus he has kept enough to spare and you can't do much about it than trying to use it!!!

Answer 3

Scientists thought this in the past because there was no activity coming from large areas when people were thinking. We later discovered that the "non-active" areas are used from memory storage, so we do actually use all of our Brain.

Think of it this way: how big is your computer's processor compared to the hard drive? The processor does all the "thinking", but the hard drive is important too.

Answer 4

Imagine if we were able to use all of our brains! Wouldn't that be amazing? Guess what? We do!
Well, I do. I don't know about some of the people I know, though...
I have heard that people only use 10% of their brains potential.

I hope I have helped!

Answer 5

Good question. i heard most of the brain after tens of thousands of years of evolutionary process we dont need it anymore. so it's "hibernating".
though in tibetan meditation teachings, they say that there's a certain sleepig part inside the brain, they refer to as " the third eye", when awakened, unlocks mass amounts of intuition/wisdom. dont know if this is true...

Answer 6

it is not that we use a small percentage of our brains, it is that they get picked by people who either have no brains or are jealous, and cannot think for themselves,

Answer 7

There are people that use their entire brain at once.
They are called epileptics, and they are having a seizure!

Answer 8

My guess is that it's used for memory and involuntary actions.

Answer 9

it is the way humans have evolved- we no longer need all the primitive survival areas.

Answer 10

I don't know but it sure explains why everybody is so STUPID
