This Brain island is cool and all, but it's not real per se.

Your brain is very real, and it's a little.

While you're watching this, I'll need a few basketballs, please.

If you choose to accept it, count how many times the basketballs were passed around by the people in white shirts.

Watch closely, as the basketballs might end up being passed elsewhere.

So, did you happen to catch the gorilla walking in the background?

the arms of the people in the black shirts were inflating slightly.

Okay, next up, we're gonna see how fast you can count this time.

So count the footballs as they fly across the screen and see if you can spot the one soccer ball.

It'll happen quickly, so get ready to count.

Did you see the message on the scoreboard, though?

If you watch these videos again, you'll most likely see all the details without any problem.

So why did you miss them the first time around?

To answer that, we need to get back to the brain.

This is where your visual information is processed and translated into objects.

This happens in 200 to 300 millisecond periods of time, called fixations.

But of course, the world is full of visual information, especially in fast paced areas like a busy street or a sporting event.

So for each fixation, your brain focuses on what it thinks is the most important at the time, selects the relevant visual information, and

The rest of the visual information is barely comprehended, which is why you may not notice it.

But don't just take my word for it, Just try it out.

This image was created by researchers studying attention illusions, like the ones we showed you at the beginning of the video.

While keeping your eyes on the blue dot in the center, focus your attention on one of the surrounding gray circles.

Did you notice that the circle becomes brighter than the other two in reality?

Your brain's not illuminating that circle.

It's actively suppressing the two circles you're not focusing on.

This can lead to your brain outright ignoring objects or people in your line of sight.

This phenomenon is known as inattention blindness, where you don't see things that are right in front of you simply because you're paying attention to something else.

This may be because you're completing a certain task like counting passes or footballs, or because something is distracting you, like a bright color movement or a familiar face.

But this doesn't only happen when there's a lot of visual input.

It also occurs when your brain is expecting to see something.

Don't worry, we won't hide anything in the background this time, so go ahead and read this.

Then your brain completely missed the extra the if you like this video, let us know and we'll bring you more brain related topics like the philosophical zombie experiments.
