This sounds like an assumption.
In fact, it sounds like the same thing I've been hearing for 20 years
Is it still true that we use only ten percent of our brains?
No, that is nothing but a myth.
The 10% statement may have been started with a misquote of Albert Einstein or the
misinterpretation of the work of Pierre Flourens in the 1800s. It may have been
William James who wrote in 1908: "We are making use of only a small
part of our possible mental and physical resources" (from The Energies of
Men, p. 12). Perhaps it was the work of Karl Lashley in the 1920s and
1930s that started it.
Perhaps when people use the 10% brain statement, they mean that only one out of every ten nerve cells is
essential or used at any one time? How would such a measurement be made? Even if neurons are not
firing action potentials, they may still be receiving signals from other neurons.
