How did scienctist discover what percentage Einstine used?
What happens to the part of the brain not used is it just dormant?

Thank you Frank N for your informative input. I usually learn something new in this forum!

That wasn't discovered, it was hypothesized. That hypothesis has since been discredited. The idea probably started from observations of when neurons fire. But the brain works by parallel and associative processing. Picture 1000 students in an auditorium. The speaker announces, "Charles Smith, please stand up." How many students responded? The five who stood up? Yes, but also the 993 who listened, decided they were not Charles Smith, and stayed seated. Only the two who were asleep didn't respond.
That's a good metaphor for how the brain works. Each neuron continually 'listens' to its inputs. Once the state of the inputs matches its training, it fires. After a brief recovery period, it's ready to do it again. It doesn't matter what the rest of the brain is doing, it responds only to its inputs.
Intelligence is a measure of how well some of these processes work or are capable of working. Mental competence and performance is a function of intelligence plus training and practice.

That is a commonly misinterpreted fact. We do use all of our brain, just not all at once. At any given time we are only using ten percent, but in one second that could be the ten percent int the front, then next second the ten percent in the back, and so on.
In the rare case where part of the brain is unable to be used, as in lobotomy or stroke, the unused portion of the brain atrophies and dies.

We use most of our brain, but we don't use it all at the same time.
People who have more overall intelligence (if there is such a thing) don't use more of their brain than anyone else. In fact they may even use less of their brain because it's more efficient.
