According to a survey from 2017, around 65 percent of Americans believe that we only use 10 percent of our brain.
But this is just a myth, according to an interview with neurologist Barry Gordon in Scientific American. He explained that the majority of the brain is almost always active.
The 10 percent myth was also debunked in a study published in Frontiers in Human Neuroscience.
One common brain imaging technique, called functional magnetic resonance imaging (fMRI), can measure activity in the brain while a person is performing different tasks.
Using this and similar methods, researchers show that most of our brain is in use most of the time, even when a person is performing a very simple action.
A lot of the brain is even active when a person is resting or sleeping.
The percentage of the brain in use at any given time varies from person to person. It also depends on what a person is doing or thinking about.
