Visual brain teasers are a great way to stimulate your brain. These “optical illusions” show that not everything you see is true! According to Susana Martinez-Conde, director of the visual neuroscience laboratory at Barrow Neurological Institute in Phoenix, Arizona:

“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 fun way to pass the time, but they are also beneficial to your intelligence! This frog image, for example, is actually a photograph of something quite else!

Yes, that is a photograph of a frog. Is there more to it, though, than meets the eye? Take a good look! Don’t give up too easily; all it needs is some time and patience to recognize that this frog image is of a different species! Technically, this image is not an optical illusion.

This is due to the fact that it has less to do with optics in your eye and more to do with how your brain functions and perceives images. “The brain is always constructing things, which helps you survive,” explains Mark Changizi, a neurobiologist and assistant professor of cognitive science at Rensselaer Polytechnic Institute. Some of these structures could be made up.”

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 spot the hidden animal in this frog image?

Don’t be alarmed; it’s not that simple! So you’d be entirely excused if you didn’t notice the other animal. Even though the horse is in clear sight, I struggled at first! Are you ready for the big reveal?

Here comes the horse!

Take another look at the frog photo. He has been emphasized this time. If you can’t see the horse, the second image will make you say, “OH! “There you have it!”

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