** [https://www.sciencealert.com/a-man-who-lives-without-90-of-his-brain-is-challenging-our-understanding-of-consciousness This] 44 years old public servant uses 10% of his brain, all the time, because, well, 10% is all that remains.
* One source of the myth itself (of many possible ones) is a series of experiments done on rodents in whch the poor creatures had large parts of their brains burned away but could still run a particular maze. However, all this proves is that memory is distributed in the brain rather than localized; the rodents still lost other functions. Besides, mice aren't men.
* Approximately 90% of cells in the brain are not actually neurons, but glial helper cells that keep the neurons alive and functioning. So only 10% of the cells are used directly; the other 90% are vital to keeping that 10% healthy and alive.
* The famous [[wikipedia:Phineas Gage|Phineas Gage]] had a railroad spike driven through his brain, causing massive damage to his frontal lobes. Besides being the logic center of your brain, the frontal lobe also controls your personality. He recovered and his memories and abilities were intact, but his friends said he was "no longer Gage" - he lost his moral compass and was much more irritable, profane, and dishonest. (To be fair, who ''wouldn't'' be incredibly irritable after having an iron spike driven through their head?)
* Dolphins and other cetaceans have adapted to function actively while 50% of their cerebrum is ''asleep''. This is good, since their breathing is entirely under conscious control, and total loss of consciousness thus equals suffocation.
