Scientists have a new explanation for one of the weirdest features of our brain – phenomenon déjà vu. Scottish Professor Akira O’Connor believes that the “Matrix inverse” is only a process of verifying facts by our own brain.


To prove this theory, Dr. O’Connor has carried out a number of experiments that artificially included the challenge of déjà vu. The method was to show the participant of this experiment, a series of words associated with common, but deliberately abandoned concepts. For example, in a series; pillow, bed, night, no sleep.

Immediately after the participants were told this string of words, the researchers asked them whether they heard the word with ‘s’ in it, and the answer was negative. However, later, when the same question was posed to them, participants generally said ‘sleep’. Participants were thinking as if they actually heard the word because “sleep” was a very logical addition to a series. The brain of the participants was overwhelmed by their own memories, which then led them to feel a powerful déjà vu immediately after.

Functional magnetic resonance showed that the most active parts of the brain at those moments were those responsible for making decisions, not memories. Dr. O’Connor assumes that these areas of the brain create a déjà vu because they follow our memories and look for errors in them. When they find inconsistency, they are activated one time, and we experience a frustrating feeling as if that had happened before.

Another researcher, Stefan Köhler from Canada, thinks that there is some clash of brain events during déjà vu.


Scientists still need to collect more data to prove these theories. But if they are truly true, the déjà vu a phenomenon will ultimately be resolved and expanded. This will then mean that our brain checks the quality of our memories and seeks inconsistencies between what we really remember and what we think we have remembered.
