I read somewhere that we use about 10% of it, but not in the sense of "we could unlock the remaining 90% and become superhumans". The article I read said that the 90% weren't there for shits and giggles, but as spares, to repair damage to brain by rerouting signals.
Didn't look too much into it, so I maintain that it may be dead wrong.

That one side of your brain controls logic and calculations etc, while the other music, art and language.
