How do optical illusions manipulate the brain?

I will talk about what optical illusions are, the three types of illusions, and lastly how do optical illusions manipulate the brain. I will also some examples of optical illusions.

Problem

How do Optical illusions manipulate the brain?

 

Method

I used websites. 

  • I tried using websites that are very known
  • I looked for websites that specialize in the kind of information I am seeking
  • Tried finding websites that are from the 2000 (not less or it would be too old)
  • Does the webpage have any authors listed?
    • If yes does it have back up information?​​​​​​​

Research

How Do Optical Illusions Manipulate the Brain?

Hypothesis

My hypothesis is that the brains of different people can interpret the images they see in different ways.


What are optical illusions?

Optical illusions are shapes, images or designs that make you see things differently than they actually are.


Know the three different types of optical illusions.

  • Literal: Literal optical illusions can be created by putting together different smaller images to make up a main image or focal point. 

 All is a Vanity (1892) .  By: Charles Allan Gilbert

  • Physiological: A physiological illusion is when The eye “sees” so much of light, movement, tilt, color, dimension and size which causes confusion in  the brain.

Hermann Grid Illusion (1870) Ludimar Hermann

  • Cognitive: Cognitive illusions are based on an individual’s assumption about the world. Each of us has different ways on how we see things based on our awareness and consciousness. 

Rabbit or Duck (1892) By: Jospeh Jastrow


How do optical illusions manipulate the brain?

The retina receives the impulses of light from the eye and sends them through the optic nerve to the brain. The brain then processes the data and interprets it as images to become like reality the way we (humans) know it.

CAUSES...

Most optical illusions happen either from the sensory center when they are received by the retina or they are caused by misinterpretation when they are processed in the brain.

Story of Prophet Musa (Moses): Was it an optical illusion?

Summary and Conclusion

Data

Some Images I wanted to include but couldn't:

Conclusion

My hypothises was partly correct, beacuse most optical illusions happen either from the sensory center when they are received by the retina or they are caused by misinterpretation when they are processed in the brain.  Also different brains of different people interpret the images in different ways so it it is different for everyone.
