Do we really use 10% of brain?

We have heard the saying from many that we use only 10% of our brain or some might go to the extent saying we use only 2% and more over they add that if we could never use our 100%. Some also say Albert Einstein itself used only 20% and bla and bla...

So, We took their taunt or advise as truth and believed it. Even though their claim was not supported by any research or Fact.

But now a new research has proved them wrong. Below is the article published in Economic Times on 8th December, 2012

The 10% of brain myth is the widely perpetuated urban legend that most or all humans only make use of 20%, 10% or some other small percentage of their brains. It has been misattributed to people including Albert Einstein. By association, it is suggested that a person may harness this unused potential and increase intelligence.

Origin of Myth

The 10% myth most likely arose from a misunderstanding of neurological research in the late 19th century or early 20th century. For example, the functions of many brain regions (especially in the cerebral cortex) are complex enough that the effects of damage are subtle, leading early neurologists to wonder what these regions did. The brain was also discovered to consist mostly of glial cells, which seemed to have very minor functions. Some early neuroscientists used the figure of about 10% to refer to the proportion of neurons in the brain that fire at any given time or to refer to percentage of the brain's functions that had been mapped at the time , it is easy to imagine that the myth propagated simply by a truncation of the statement that "humans use 10% of their brains at any given time."
