That is untrue. PET scans of the brain show that much of the brain is active. From an evolutionary point of view it does not make sense for the brain to develop 90% of useless brain either. It is established and proven that we use 100% of our brain, but not all of it at the same time, we use different parts for different reasons but overall the whole brain is used. Therefore do not be tricked by those adverts offering to tap into your unused brain power as you probably don’t have such a thing as unused brain.
