You only use a small portion of your brain at any given time. Like if you're listening to what someone is saying, there may be activity in Wernicke's area, Broca's area, the frontal cortex, etc., but you may not have any activity in your brain where it deals with balance and movement.

EDIT: That's exactly what the dude said above me.
