In the Movie...

Norman, a brain scientist in the movie, said that the maximum human brain capacity is 10%, and the only animal among living things that uses more brain capacity than humans is the dolphin. Explain that you have the ability to do it. Norman explains that when the average human brain usage reaches 24%, complete control over the body becomes possible, when it reaches 40%, it can control everything around it, and when it uses 62%, it can even control the actions of others do. 

In Fact...

The notion that a person uses only 10 percent of their brain is a myth. It's still unclear exactly what percentage of our brains use, and the numbers in academia are constantly changing. Because of the organ’s complexity, scientists are still learning about the brain.
