what percentage of our brain do we have access to
Best Answer: We usually use an average of 3% and 10% of our brain at the time. This doesn't mean that the rest of the brain is not accessed, it's a common misconception coming from the idea suggested by some psychologist that we only use 10% of our potential: it only means that let's say you're studying, you have the potential to do 90% better, you just don't know how to do that. We actually access 100% of our brain: as a matter of fact, even the smallest damages to the brain cause some kind of disability, regardless which part of the brain has been damaged. Accessing the brain and using the brain are 2 different things: we actually access all our brain, but that doesn't mean that when reading this post you're using all of it, as every part of the brain has different tasks.
