I always thought there was something a bit fishy with this one. It made no sense that brain matter (As exremely valuable as it is and impotant as it
is) would sit there housed in your bones waiting to be "unlocked".
While I do beleive the mind is capable of man great things, even things we do not understand; from what I have gathered in readings is the 10% saying
is false. We in fact use much more of our brain at any given time.
Below are some excepts from an article written a while back I came across that might help to answer some questions...
Imaging the Active Brain
"In addition to clinical evidence, brain imaging methods appear to refute the 10% brain use statement. For example, positron emission tomography
(PET) scans show that much of the brain is active during many different tasks. Often when brain scans are published, they have been manipulated to
show relative amounts of brain activity rather than absolute activity. This graphical presentation of the data shows differences in brain activity.
Therefore, it may appear that some areas of the brain are inactive when, in fact, they were active, but at a lower level compared to other sites.
Brain scans only show activity for the carefully designed isolated tasks being tested, such as memory or visual processing. They do not show activity
related to other untested abilities. Imagine the brain is a restaurant kitchen. If you looked in on the kitchen at one time, you may see the chef
preparing salad. However, you may not know that the main course is cooking in the oven. Similarly, if you image the brain during a visual task, you
will not see the other patterns of activity associated with performing different (simultaneous) tasks."
Evolution and Development Weigh In
"From an evolutionary perspective, it is unlikely that a brain that is 90% useless would develop. The brain is an expensive organ to maintain and
utilizes a large supply of the body's energy resources. Certainly there are redundant pathways that serve similar functions. This redundancy may be a
type of "safety mechanism" should one pathway for a specific function fail. Still, functional brain imaging studies show that all parts of the brain
function. Even during sleep, the brain is active. The brain is still being "used"; it is just in a different active state."
Here is the direct link to the article, iteresting read but this is about the gist of it...
