Because the other percentage is used to control involuntary actions (things that are not under your conscious control) such as the heartbeat and the proper regulation of breathing.

That's just a myth. In actuality, every part of the human brain has a known purpose; the entire brain is used. It is true that only about 10% of the brain's neurons are firing at any given time, and that about 10% of the brain's cells are neurons, but they are always used at the capacity required for a given task. In fact, the brain of a more intelligent person is less active when performing the same tasks as a less intelligent person.

This is an urban myth.
There is a very wide-spread belief that we humans only ever use 10 to 20% of our brain. Attributed to Albert Einstein, it is one of the ‘grab’ statements used to recruit people for the cult of ‘Scientology.’
The reason for its wide acceptance may be because Dale Carnegie’s popular 1936 book, How to Win Friends and Influence People, stated that most people only use 15% of their brains—a ‘fact’ probably pulled from thin air.

Well, the other 81% are just for display. How many % do you use? Because "there" should be "their".
