We have all heard of the stories that we humans only use 10 percent of our brain capacity. These allegations all imply that the unused 90 percent of the brain is capable of extraordinary feats, namely psychic powers, telekinesis and ESP.
"It is a myth that man uses only 10 percent of present brain capacity; evolution theory argues against such a monumental waste of available resources."
Evolution theory engineers all beings to be as efficient as possible, thus it is highly improbable that humans would have such a big percentage of unused grey matter. Neurologist Barry Gordon (famous for his efforts in debunking this myth) states that man uses virtually every part of the brain, and that [most of] the brain is active at all times.
Gordon also tells us that the myth's durability feeds on people's conceptions about their own faults as being attributed to untapped brain power. What is correct, however, is that at certain moments (rest/sleep) we might be only using 10 percent of the brain.
The human brain consists of the cerebellum, the cerebrum and the brain stem. (Basic high school biology/science class knowledge that you already know. Otherwise: http://tinyurl.com/dfrk89)
The cerebrum is the large hefty blob that is responsible for all cognitive functions. The cerebellum manages all your motor functions; while the brain stem is dedicated to involuntary actions such as breathing.
The majority of the power consumed by the brain powers the rapid firing of millions of neurons communicating with each other. Scientists think it is such neuronal firing and connecting that gives rise to all of the brain's higher functions.

Evolution: The brain is enormously costly to the rest of the body, in terms of oxygen and nutrient consumption. It can require up to twenty percent of the body's energy--more than any other organ--despite making up only 2% of the human body by weight. If 90% of it were unnecessary, there would be a large survival advantage to humans with smaller, more efficient brains. If this were true, the process of natural selection would have eliminated the inefficient brains. By the same token, it is also highly unlikely that a brain with so much redundant matter would have evolved in the first place.
TL;DR :It is a myth that man uses only 10 percent of present brain capacity
|Where are we going?|
We are getting closer to the Corridor Theory.
Consider the notions:
if neurons could be smaller and still fulfill their role in the brain.
What happens when man finally discovers the boundaries of the universe?
Can escape velocity can be applied to the universe? On such scales, where the (approaching) infinite number of forces interact together, what happens?
And the most important question of all:
All of the above are under investigation, and (the findings) would be presented in a more concise format when the time comes. No promises.
