just an idea

[foolish]

No, the thing with the water is right, however is it 90%? Maybe more like 80… When you dehydrate you get a headache, this is because parts of your brain start to dry out. I’m not sure why but maybe the braincells work so hard they use up a lot of water, so the 90 or 80 or whatever percent is like a reservior, waiting to be used up.

One interesting thing is that the percentage of water in our brains is very similar to the percentage of water on the planet…

As for how much of our brain we use, I have no experience in this field but here are some of my suggestions:

Maybe we are only capable of using 10% at one time?? We still use the whole brain, but at different times. Perhaps the subconscious needs 90% to work, otherwise we could overload our brain with too much information and get confused. Like feeding so much info to a computer until it crashes.

Again I am claiming no experience in neuro-psychology, these are just ideas and possibilities I have thought about. Another thing I have heard is that the 90% is used for psychic abilities. IMHO this is not impossible. My own thought on the matter is that we only need 10% to carry out bodily functions, monitor senses, do normal everyday tasks and feel emotions. Think about how people only seem to do the minumum amount of work they can, spending more time playing (i.e. in this context, playing with subconscious thoughts) The other 90 can be utilised, but we really cannot be bothered to use it.

Perhaps enlightenment includes this… using your full potential and making use of everything. In which case LD are an important step towards self-knowledge as they use your conscious mind in combintion with limitless imagination, helping you to use the rest of your mind. Sorry, brain.

I will stress again that I know NOTHING about this. These are just possibilities that make some sort of sense to me. By all means criticize what I have said. Only by careful thought and refining of ideas can we get close to the truth. I hope we get close soon.

Shade, You are right.
The whole 10% thing is a myth…

ok i am going to quote myself

ok i dont know if i missed somthing here but how do we know what using 100% ofour brains is like. i mean how whouldthey know if we were using all our brain power any way. it is easy to see if a car is using all its power, just push the acc. but then the car gives in. no fule. could we do this to a human? i think not. for one it is unethical nad two, in my opion impossible. humans stop when they think theyare at their limit but really they are no hwere near it. “we can go further after we say we cant than we know”.

that pretty much sums up my point. how do they know we are using it all we got.

From the Snopes article:

1. 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.

2. The myth presupposes an extreme localization of functions in the brain. If the “used” or “necessary” parts of the brain were scattered all around the organ, that would imply that much of the brain is in fact necessary. But the myth implies that the “used” part of the brain is a discrete area, and the “unused” part is like an appendix or tonsil, taking up space but essentially unnecessary. But if all those parts of the brain are unused, removal or damage to the “unused” part of the brain should be minor or unnoticed. Yet people who have suffered head trauma, a stroke, or other brain injury are frequently severely impaired. Have you ever heard a doctor say, “. . . But luckily when that bullet entered his skull, it only damaged the 90 percent of his brain he didn’t use”? Of course not.

That’s how they know.
