I dont know how much Einstein use but i heard about juz 9% of the brain.. hmm.. kinda tangle there.. dun u think?..

average people may b can use 3% - 6%.. y?

where did about 90% of our brain gone?

Is it because its burnout just like fuse?

Seems like the <10% of brain being used was a myth.
If we use only 10% of it, is it ok then to remove the 90% since it's not being used?
If so, one would then question 'How do we know which part to remove?'

Exactly, if we do not know which part to remove, how did we came to the conclusion that only 10% is being used?

Maybe we haven't come across something that needs to fully use our brain.

We can't just use the strength of lifting 50kg dumbbell to lift a tissue paper, can we ? Not heavy enough to force your muscle to put your strength into use.

Good analogy there, I get exactly what you mean smile.gif (Although there will be people insisting lifting weights is not the same as using brain. doh.gif ).

Have any of you experienced this?

Sometimes during exam, when the questions are like very difficult, when I had to think really hard and recall everything I've learnt, after the exam I felt as though my brain has been fried. I'm saying not only headache, but I felt as though my head was heating up.

I can't exert my experience unto you guys. You might beg to differ and it's fine by me. But occasions like this is what made me felt perhaps it is true that we can't optimise our brain all the time. If the usage exceeds the rating (tongue.gif), the brain might just be fried.

Are all brains created equal?
Can our brains be trained to be equal?

Eg.
Whats the difference between a smart person and a not so smart person. Can the not so smart person be as smart as the smart person with proper training?
*
The main difference between a smart person and a not-so-smart student is just whether or not they use their brains before saying or doing anything.

And that is why i asked....are all brains created equal and can they be trained to function equally if they are not.

Sorry I can't provide an absolute answer to your question, but I can only give you my opinion.

As someone has mentioned, neurons are unlike muscle cells that can regrow and replace itself.
But, will inactive neurons die off? That I'm not sure. (It'd be helpful if someone can provide some proof to this)

However, I know for a fact that if one sharpens his/her mind, the brain can be used more efficiently.
Practice makes perfect perhaps?

I think this is also one of the possible reason. Maybe when your brain usage passes certain limit, you will start to feel dizzy, headache, pass out or even die as long as you could force yourself to break that limit which is kinda impossible in my opinion. When you try to push your brain over a certain limit, your brain starts to warn you with the symptoms mentioned, making you weak and unable to continue.

It's like trying to choke oneself to death, you would pass out and breath reflexively before you are even dead.

I remembered reading an article that a Korean guy passed away after playing a computer game (It's Starcraft, I think) non-stop for >48 hours.

im just talking about the brain, bro. not personality and physical attributes.

Likewise, how the neurons are created aren't equal for everyone. For some unlucky ones, the neurons didn't develop, and hence became mentally challenged.

3-6% for thinking... other for background process... if wanna knoe, ctrl + alt + del, click at process tab.. u'll see wahts background process u r doing

The thing about this is, how did the idea of 3-6% of the brain being used, comes about?
For one, we can't determine which part of the brain will be functioning for what specific purpose.
I do remember there was a chart showing which part of the brain controls which function of the body, but I wasn't aware if there was any scientific backings to that.

I could be wrong, I'm open to ideas and further discussions. smile.gif

The percentage rating of brain usage to me is a total nonsense. Those researchers who came up with that claims didn't really know what was going on also. If you do read up more about how the brain function, the brain is like a System Unit (a whole computer).

And inside a computer you have different parts like GPU, CPU, sound cards and stuff. Our brain has specific regions just for that specific job. Some people who suffer from certain brain disease, neurologist sometimes temporary disables certain part of the brain to identify the problem.

You can't rate the brain like say "oh, my brain only running at 6%". Cuz your brain is not just one big part itself, its multiple parts joined and working together; a component. So if some random guy comes saying, "my brain is running at 100%!". So he's saying that the speech control part is working non-stop, aka he won't stop talking. Imagine every part working at maximum, fear control and all those- the person will go kookoo. Feel scared, brave, funny, and everything at the same time.

And the thing about being smart, to me everyone is smart. But the question is, smart in which situation?
Some of us might be PC pros, but if we were sent for guerilla warfares, how good are we? The only time when one is not smart, maybe brain disablilities...

Correct, exactly as what we've been discussing so far.

Perhaps the percentages quoted has already included everything u mentioned above, leaving roughly 90% + more of our brain yet to be explored.
*
XD Aha! How do we know that?
But it'd be wonderful if we can device a method to point out which section of the brain does what.

there are somethings in life, we just couldnt find answers for

why pigeons are able to find their way home, despite thousands of miles apart?

why the earth circles the sun in perfect timing/order, never missing its proper cycle?

why we are different from any other animals, despite all having brains?

or the ever question - why are we here?

We human are curious creatures. We'd seek answers to all questions.

For questions that we can't answer, there's religion.

Correction. Muscle cell can't grow and replace itself.. When you have a tear or an injury on a skeletal muscle, fibrous tissue will grow in it's place, thus replacing the muscle tissue in it's place. Thus you'll never gain 100 percent of it's function back...

And why would skeletal muscle seems to grow larger when we go to gym or workout? They undergo hyertrophy which is an increse in cell size, not hyperplasia which is an increase in number of cells... biggrin.gif

I see. Thanks for clearing it up. I do admit this isn't my field of study, was just recalling some biology knowledge in SPM. biggrin.gif
