Déjà Vu is a French term meaning “already seen” and it’s reported to occur on an occasional basis in 60-80% of people.
Researcher Akira O’Connor using magnetic resonance watched the work of the brain of volunteers who during the filming underwent a procedure that causes the same feeling like Déjà Vu. He discovers a sense that produces parts of the brain responsible for checking existing memories and not the false memories.
What does it means?
This means that Déjà Vu is not a mistake in our brains, but error prevention or correction of the error in our memories. One theory is that Déjà Vu indicates good memory, while another theory is that it may be a sign that people do not experience Déjà Vu have a better memory, because the system does not need to prevent error.
