Optical illusions, which make us think our brains are playing tricks on us, are among the methods used in the scientific world to understand the brain. A How we perceive optical illusion may shed light on our evolution.

One of the latest studies in the world of science has just been published. This time, the illusion that was examined and judged on our response was the one you see below:

One side of the bar looks lighter and the other side darker, right?

Not really. This rectangle has only one color. But due to the gradient in the back, our brains do not perceive any color. So, why does our brain see it that way?

Here is the secret behind this illusion revealed in the latest research:

In new research published in PLOS Computational Biology, Dr. Jolyon Troscianko and his team show the gray bar in the image above. why we see it as different colors investigated.

• Analysis of an illusion through the eyes of the model. As can be seen at the top right, he himself is a victim of illusion and sees tones differently.

Previous research has demonstrated this illusion lack of processing power of our brain claims to have arisen as a result. But Troscianko came to different conclusions.

The team used a computer model that shows how we see optical illusions by mimicking our eyes. Simply put, the model trained with natural images after being exposed to various illusions He was stunned to see the high contrasts. Later he began to perceive illusions in the same way as humans.

So what does this tell us?

The model, which sees natural images like the human eye, suddenly encounters high contrasts and sheds light on human evolution. According to scientists, the model is intended for functions such as seeing variations of neurons in our body in different colors. how you evolved reveals.

In other words, the reason why we fall into these illusions is because of the evolutionary process that we have been in for hundreds of years. It is due to the proportion that falls on our eyes to distinguish colors from each other.
