Check Out the Optical Illusion That Doesn’t Allow You To See All The Dots At Once

Well, our life is very much limited by as much as our brain let us do. Everything like smells, light, shapes, colours etc. depends on our brain and in case it is not damaged or injured, we perceive everything in an average way, like others do. In order to understand how our brains work, optical illusions is one of the methods to do that. They are scientific tests to assist in observing the human brain.

Popular across the internet in recent times, the grid optical illusion picture is among the good samples of an optical illusion. The picture is a version of Jacques Ninio’s works on the Hermann grid as an extinction illusion. The origin of this picture is the page of Psychology Professor Akiyoshi Kitaoka, from Kyoto, Japan. 12 dots are included in it, however our brain does not let us see them all accurately. Only 4 dots are seen by an average person.

Two types of nerve cells fill the retina known as rods and cones. They can detect or sense light. Rods become more active in low light and therefore are responsible for sensing the low levels of light.

There is one problem that only black and white or shades of grey can be detected by them. As light enters our eyes, the nerve cells start communication with others and some of them communicate that others can ‘sleep and rest’. This is called lateral inhibition by scientists. As per neurobiologists, a contrast in stimulation is created by this which allows increased sensory perception. Also known as lateral antagonism, it occurs mainly in visual processes.

First of all, the most obvious parts are being picked by our brain to see, and the rest of the image requires more attention and focus to be seen. Basically, this is what is going on in this image. Your brain fills the uncompleted parts in the picture in accordance with the patterns it identifies in the rest of the image. Therefore, the correcting capacity of the brain is based on how much information your brain can handle and store at one time.

Appointed in a geometrical grid base, there are really 12 dots in that picture. Only 4 of them are seen at the first sight, however, if we concentrate to see them all, we become capable of seeing them provided that there is no mechanical problem in our eyes or brain. There are some diseases such as dyslexia which cause more complex problems with processing the data, and the brain completes the missing parts faster than normal.

In order to understand the precise reasons for them, scientists like the Psychology Professor Akiyoshi Kitaoka and Jacques Ninio, are still working on visual illusions. The brain is a micro universe and there are still many mysteries to solve. The only thing we can do is have fun by looking at these optical illusions.
