Visual mind teasers are an excellent method to stimulate your brain. These “optical illusions” demonstrate that not everything you see is always true! Susana Martinez-Conde, director of the laboratory of visual neuroscience at Barrow Neurological Institute in Phoenix, Arizona, says:

“They’re important tools in visual research because they help us understand how visual processing works in both the normal and diseased brain.” That is, they are not only a pleasant method to keep yourself busy, but they are also good for your intellect! This frog photo, for example, is actually a picture of something completely different!

Yes, that is a frog photo. Is there, however, more to it than meets the eye? Take a close look! Don’t give up too easily; all it takes is a little time and patience to realize that this frog image is actually of another species! This image is not, technically, an optical illusion.

That’s because it has less to do with optics in your eye and more to do with how your brain works and perceives images. “The brain is always constructing things, which helps you survive,” says Mark Changizi, a neurobiologist and assistant professor of cognitive science at Rensselaer Polytechnic Institute. Some of these structures may be fictitious.”

So, what do you see in the image below? Do you just see the frog sitting on the ground or perhaps at the edge of a pond?

Still can’t see the hidden animal in this picture of a frog?

Don’t worry; it’s not that simple at all! So you’d be completely forgiven if you did not manage to spot the other animal. Although the horse is hidden in plain sight, I struggled at first, too! Ready for the revelation?

Here’s the horse!

Have a look at this picture of the frog one more time. This time he has been highlighted. If you still are not able to see the horse, the second image will make you say “OH! There it is!“

Just flip the image around and hey presto! You’ll see the horses head.
