Why do people say that we only use a small percentage of our brains. And if its true what is the rest for?

Hate to burst your bubble, but you use 100% of your brain all the time. You may be consciously aware of only 10% of your brain activity, but the other 90% is always working. Think of all the activity your brain has to mediate....sensation, perception, thoughts, movement, your circulatory system, your circadian rhythm....and that's just the tip of the iceberg.


Almost every nerve cell in our brains is active most of the time. Scientists can detect this activity by measuring the electrical currents of nerve cells near the surface of the brain. More complex tests like PET (Positron Emission Tomography) can detect oxygen consumption, blood flow or glucose consumption (the sugar that is the brain fuel) by active neurons in all areas of the brain, not just the surface. Just about ALL of the human brain is busy all the time鈥攅ven when we're sound asleep.Why do people say that we only use a small percentage of our brains. And if its true what is the rest for?
To keep your ears from clapping together in a strong wind.Why do people say that we only use a small percentage of our brains. And if its true what is the rest for?
Because each part of your brain is for a certain function.
the rest is used for storage of data and autonomical nervous systems however one can be trained to access more areas for practical purposes such as creativity and problem solving
