So, cool idea for a movie – if we used 100% of our brains we could eat a mountain for breakfast, and memorize The Tale of Genji while brushing our teeth, and get from Seattle to Stockholm in a single bound. Except that we couldn’t, because we already do, and we can’t.
The fact is, people use all of their brains. Brain imaging research techniques such as PET (positron emission tomography) scans and fMRI (functional magnetic resonance imaging) clearly show that the vast majority of the brain does not lie unused. Although certain activities may use only a small part of the brain at a time (for example, watching reality TV shows), any sufficiently complex set of activities will use many parts of the brain.
