How does our brain put in order all the information that every second receives? A million dollar question but the answer, according to scientists, could be in two optical illusions that trick the brain into time travel to remember everything we thought we had forgotten.

How does our brain put in order all the information that every second receives? A million dollar question, but the answer, according to scientists, could be in two optical illusions that deceive the brain and make it travel through time to remember everything we thought we had forgotten.
So many times we have shown you optical illusions, but these are truly unique: one is visual, the other auditory, but they go hand in hand because both were created by a team of scientists from the California Institute of Technology.
They are called The Illusory Rabbit and The Invisible Rabbit and their mechanism has been explained in Plos One magazine. According to the team, optical illusions can investigate decision-making: how does the brain determine what objective reality is?
"It relies on assumptions given by the surrounding environment: if those assumptions are wrong, the brain is wrong," explains Noelle Stiles, co-author of the study.
Going into detail, these two illusions were created to show comand the present can alter the perception of the past, thus we speak of postdictive processes. Without going into science in the narrower sense, let's try to do the experiment directly.
Watch this video how many flashes do you see?
Explanation
Are you still trying to understand? After the initial bewilderment, let's try to explain what happens in the video. Flash and sounds are played simultaneously. The combination is three times in a row at a distance of 58 milliseconds, and the flashes appear from left to right.
As seen from the image in The Illusory Rabbit, the central flash is not shown, yet our brain hears three sounds and goes back in time by inserting the missing flash. In The Invisible Rabbit, it is the central sound that is not reproduced and the brain automatically cancels the central flash as well, under the illusion that it has not seen it.
According to scientists then the brain tends to alter what he had perceived in the past to make it consistent with the present.
