Optical illusion of a ‘hollow mask’ reveals shocking truths about the way your brain is wired – what do you see?

ONE optical illusion of a hollow mask reveals shocking truths about how your brain is wired.

The hollow mask illusion activates certain regions of the brain.

The rotating hollow mask presents an optical illusion

In this illusion, you may perceive a concave face, as if you were to see the back side of the mask, as a normal face.

The illusion calls upon the way our brain processes the visual world.

This means the brain is using bottom-up processing, or what it usually sees, with top-down processing, which is what it expects to see based on previous experiences.

Because of this, we may not pick up on shadows and depth perception.

But not everyone will be able to see this illusion.

For example, those who live with schizophrenia may not be fooled by this illusion.

That’s because the sensory and conceptual areas of their brains are wired differently.

The same may be true for those who are under the influence of alcohol or drugs.

The face presents an interesting illusion for other reasons as well.

Some neuroscientists believe we have special relationships to faces, as we have regions of the brain specifically dedicated to processing them.

This makes it difficult to process the illusion.

But for some, the illusion is so strong they’re unable to revert to the concave face.
