People have been repeating this myth for decades. Psychics-people who say they can tell what others are thinking or predict the future-often repeat it. They say that people can learn to use the
“Unused” 90 percent of their brain for psychic activities. But it’s not true. All of us almost all of our brain, every single day.
The brain is more complicated than any computer. It receives messages about everything your body does seeing, hearing, testing, smelling, and touching. Then it sorts out this information by doing some heavy work. It remembers things, compares them, and sorts them. It solves problems you didn’t even know you had. It also figures out what the other parts of your body should do in any situation.
The brain has three main parts. The outside layer is the cerebrum. It has different areas that receive different kinds of messages. One area gets all the messages about hearing. Another gets all the messages about touch. The cerebellum is smaller brain part. It sits at the bottom of the brain. It’s in charge of coordinating muscles. The third brain part is the brain stem. This tube is in charge of keeping automatic body systems working. It keeps your heart beating so you don’t have to think about it.

It seems as if it would be hard to do all these things with only 10 percent of a brain, doesn’t it?

And indeed, doctors can prove that we use all of our brains. They use PET scans to look at the brain. PET stands for positron-emission tomography. This technology lets doctors see what’s going on side the body. With PET scans, doctors have seen that all areas of the brain are used.

NOTE:

Your brain grows until you are about twenty years old. But it can keep on learning new things long after that. In fact, your brain never really stops learning. It can make new connections until you are at least one hundred.
