Seems like close to a year ago, I believe it was on Paul Harvey News -- a
report that science suspected we may only use something like 3% of our
brain, not 10% as previously believed.
Old wives tale? Joseph Pearce claims his statements come from extensive
research. He is very outspoken - many lectures and several books. I have not
seen anyone knock him down (see reviews at amazon.com). Glancing at "Making
Connections: Teaching and the Human Brain" I see confirmation of Pearce's
information (though nothing on percent brain used). I don't believe it is a
matter of whether the neurons fire, but rather, what is the extent of
myalination occurring in the multitude of possible neural connections,
especially during youth. Also, tension shifts function to the more primitive
brain structures. Of course they would be more developed, perhaps to the
exclusion of higher brain development (except perhaps at SVS).
Anybody else looked into this? I will certainly continue - this is a vital
issue. Isn't it strange, people soon notice whether they have a watch or if
a clock is in the room, yet fail to notice if they are using their head to
