Will human ever reach the stage where we uses all the percentage of our brain?

You're probably referring to the idea that we only use 10% of our brains, but this is nothing but myth and quite easily disproved.\n\n  First of all, evolutionary, it's inconceivable that humans would evolve with such large brains only to use a small portion of it.  Metabolically, brain tissue is costly to develop and maintain.  The largest consumer of oxygen in the body is the brain.  It would be counterintuitive for all that energy to be spent on something that is only 10% efficient.  Natural selection would opt for a more efficient organ.\n\nAlso clinical evidence has shown how catastrophic losing less than 90% of the brain is to individuals.  Moreover, by observing the effects of strokes, head trauma or other damages to the brain, scientists have found that there isn't an area of the brain that can be destroyed without leaving the patient with some kind of functional defecit.  \n\nAlso, there are brain scans that can detect electrical activity in the brain in all sorts of situations.  I'm sure we've all seen a MRI or PET scan with more than 10% of the brain being illuminated with activity. \n\nThe evidence against the 10% myth is overwhelming.  One of the reasons this myth has been so sucessfully maintained is due to the New Age movement.  Many New Age "scholars" believe that man's next step great step in evolution is being able to use more than 10% of the brain and having psychic and telepathic powers as well as the ability to create your own reality with nothing more than brain power.  \n\nThe 10% theory has also had success in the media.  There have been tons of advertisements that tout the 10% myth in order to promote the potential of their product.  I distinclty remember a crappy Albert Brooks movie called "Defending Your Life" that featured an afterlife where people use more and more of their brains as they progress toward heaven.  Some science fiction films also feature "advanced" races of people with rediculously oversized heads and telekenetic or psychic abilities that also draws from this myth.

You use 100% of your brain but only about 10% at any given time. If you used 100% at any given time you would have a seizure because your brain cannot cope with so many neurons being fired all at once.

True artificial intelligence is probably not going to happen for a long time.  We still have a very imperfect idea of how the brain works except to say that it is probably quite different from how a computer works.  But even if we ever get to a computer that passes the Turing test which is the current standard for deciding whether a program is intelligent the next question would be: Is it really alive?  Would a so-called silicon life form have self awareness or consciousness or would it just be a machine going through the motions?\n\nOf course before we try to answer that we have to decide whether we humans are more than carbon based machines going through the motions.\n\nI think that before we replace ourselves with silicon minds we will find a way to enhance our bodies with artificial parts (think: a human brain and nervous system inside some sort of mechanical "body").

The more active your mind is, and the more pathways you have built in your brain, the longer it takes for you to degenerate.  It's no guarantee.

I would say about 50% think of the future. It seems to me that everything on this planet seems to be divided 50% yes'er and 50% no'ers... Dr Checko... (Nickname)

It's impossible to be all-knowing. The more you know, the more complex your brain would need to be. And that increases the amount of information there is to know. Can a computer be aware of every atom it is composed of? And to know the future is even more impossible.

I'm guessing 90 percent. The rest of us already know everything.  :-)\nPS   I'm 50

Actually, "smarter" mammal have larger brains in ratio to the size of their body.  If you were to take the ratio of size/weight of a human brain and his body and compare that with an elephant, you would find that a human's ratio is much higher.  I've heard contradicting theories with regard to actual percentage used.  We do in fact use most areas of our brain.  Why other areas are not in use probably have to do with evolution.  What sets us apart from other mammals is the amount of things we create for comfort and not survival.  All animals, there may be case by case exceptions, operate under the need to survive.  We operate under what is comfortable.

The model that humans only use 10% of their brain was a myth developed about 30 years ago and completely discredited.  The misunderstanding is due to the fact that most of the brain is not involved in conscious processing or abstract reasoning.  But's still busy, involved with sensory processing, motor control, language etc.  (and these tasks are a lot harder than we ever thought.....)

Just to add to webserfun's excellent answer:\n\n"That tired Ten-Percent claim pops up all the time. In 1998, national magazine ads for U.S. Satellite Broadcasting showed a drawing of a brain. Under it was the caption, "You only use 11 percent of its potential." Well, they're a little closer than the ten-percent figure, but still off by about 89 percent. In July 1998, ABC television ran promotional spots for The Secret Lives of Men, one of their offerings for the fall season's lineup. The spot featured a full-screen blurb that read, "Men only use ten percent of their brains."\n\nOne reason this myth has endured is that it has been adopted by psychics and other paranormal pushers to explain psychic powers.\n1) Brain imaging research techniques such as PET scans (positron emission tomography) and fMRI (functional magnetic resonance imaging) clearly show that the vast majority of the brain does not lie fallow. Indeed, although certain minor functions may use only a small part of the brain at one time, any sufficiently complex set of activities or thought patterns will indeed use many parts of the brain. Just as people don't use all of their muscle groups at one time, they also don't use all of their brain at once. For any given activity, such as eating, watching television, making love, or reading, you may use a few specific parts of your brain. Over the course of a whole day, however, just about all of the brain is used at one time or another."

You have your facts a little messed up. The truth is that we use all our brain. However, at any given moment, we are only using about 5% or less of our brain. This is why we can't do a million things at once and why some people have trouble chewing gum and walking at the same time. So while only 5% of our brain is in use at any given moment, there is not a single part of brain that does not perform a function and we do in fact use 100% of our brain throughout the day.

No one has use their brain to it maximum extent.Einstein, Newton and other Greats used 5 to 6%, which has been a proved fact.\n\nTheir brilliancy is rated based upon their expertise in a particular field and contribution to society by Nobel Prize Awards. Here are some:Peace ,Literature,Science,Medicine,etc...

It has to do with what we now know about the brain and its' development.  Younger than 18 all the parts that you need to cope and use for your self control aren't done until them.  While the brain doesn't finish 'growing' until around 20 -21 by 18 most of what you need to function in an adult world is there.

The part of the body that are use more often, become more complex, in the same manner, part of the body that are less useful to survival will eventually be select against (It waste energy without generating enough benefit). Therefore mother nature tell us that, (Darwin's natural selection) we only have what we need. If we use this as an argument. We can assume that all animals today would use 100% of the brain, those who had use less than that would have been eliminated through the course of history. Unless it was beneficial to their survival, in that case, their brain will have "de-evolve" to maintain a lower energy consuming. The process of de-evolving would led them to use 100% of their brain...

Yes.  The human mind is just an incredibly complex computer which can manufacture it's own connections.  All we need to do is get the software and hardware sides of our current technology up to the level of our brains and beyond...  Easier said than done, I know.

Even Albert Einstien could not use 100% of his brain. According to a research , humans use only 10% of their brain and Einstien used 90% of his intellect. So you can realise what the potential of human brain is. If at all you come to know how one can use 100 % of his brain , let me know too.And if you are able to do so, I hail to you as a true genius(no kidding).All the best , may god bless you!\nYours sincerely,\nVanchit

Don't get worried when u heard that we only use 10% of our brain. The president uses none at all.
