Fact or Fiction: Do we only use 10 percent of our brain?

By Suzanne Cho

Most students at MTHS have heard that human beings do not use the full potential of their brains, but this is in fact a myth.

The brain is one of the most important organs in the human body. It controls the central nervous system. It also helps with the coordination of walking, talking, breathing and thinking. The brain is also incredibly complex. However, research has gotten humans closer to understanding how the brain works, such as how much of the brain is used, as well as what parts of the brain are being used.

The brain uses its whole capacity to perform a human’s daily activities of eating, studying, thinking, playing, and even sleeping.

Brain imaging studies show that not one area of the brain is inactive. No matter what a person is doing, their brain is always active.  Here is an example:  If a person is sitting at a table and eating a sandwich, then the person is not actively using their feet. Instead, the person is concentrating on bringing the sandwich to their mouth, taking bites of it and chewing on it. However, that doesn’t mean that their feet aren’t working there’s still activity in them, such as blood flow, even when the person is not actually moving them. This situation is exactly related to how the brain works. While a person uses a certain part of their brain to do a task, the rest is still active.

Even when a person isn’t using their whole brain at one time, multiple tasks are done.

If a person wasn’t able to use a part of their brain, it would be useless and then there would no point of the brain being there.

Many people don’t realize that they are actively using the full capacity of their brains, even doing the simple things of resting and sleeping, but recent research has proven that this is correct.
