    Technologies such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) allow the activity of the living brain to be monitored. They reveal that even during sleep, all parts of the brain show some level of activity. Only in the case of serious damage does a brain have “silent” areas.

  2. Thats what we call the 40 million dollar quesition @ros0011. Who every can answer that one, has a great chance of improving that percentage and becomign very rich 🙂

    I think trying to calculate the percentage of brain used is more of a misunderstanding of how the brain works as opposed to saying with confidence that we dont understands exactly just what is happening in the brain. Maybe we should ask the Brain Zone!
