Do we only use 10% of our brain?

You've probably heard the claim that we only use 10% of our brains, leaving vast reserves of untapped potential. It’s a fascinating idea that has captured the public imagination—but what does science actually say? Take a moment to consider whether this claim might be true or false, then click "Read More" to find out!

It's false!

The idea that we only use 10% of our brain is one of the oldest and most famous neuroscience myths, but modern science has thoroughly debunked it. Thanks to advanced research tools like MRI and PET scans, we know that every part of our brain has a purpose— whether it’s helping us speak, solve problems, process emotions, or control basic functions like breathing. We don’t use our entire brain all at once, but that doesn’t mean 90% of it sits there doing nothing. Think of it like a soccer team: not every player is on the field at the same time, but each one is important when it’s their turn to play!
