I don't think there is a technical answer to this as I don't think anyone has ever ran their brains to full capacity.. How could you say that a person has used 25% of their brain when there's no way to measure the 100%.. I heard many years ago that Einstein only used 15%.  How do they know this?? 

I would guess that if a person had an accident and lost 25% of their brain matter physically lost it and recovered, they are now functioning on 75% of their physical brain.. 

Storage and logic potential has no percentage, we have no way of measuring this.. I know of no person in history that had overflowed their mental storage capacity. or just one day, their brain blew up.. LOL

I use a small percetage, say about 10%, of my brain.  That's why I seldom need to take Tylenol for headache.

That depends on where their brain is situated.

" Through the course of a day we use 100 % of our brain."

Less than 10%, for sure.  Judging by some of the spelling and questions here (and I love all of us), I'd say there are a few who use less than 5%.

We are supposed to keep our brains stimulated.  Puzzles like sudoku are good because they encourage us to use our logical and reasoning skills.

The statement about we only use a small fraction of our brains is total rubbish. Then again it depends on what you mean. Most of the time we attend to some specific and the " usage : of our brain is limited. Obviously when the cognitive load of a particular task, or task number would increase the " Fraction of the brain " That we use. So ; The short answer is; We use all of our brain.
