Déjà Vu What Happens in the Brain

Abstract

Déjà vu is a common phenomenon that most healthy people experience. Despite its commonness, it is difficult to stimulate in a lab situation, making information on this experience scarce. In order to combat this, researchers have come up with multiple theories on where déjà vu takes place, what occurs, and why it actually happens. Researchers have also begun to study mental disorders that involve déjà vu in order to possibly learn more about the elusive experience. Understanding déjà vu is crucial to gaining a fuller understanding of memory, and how the brain reacts when memories are altered or off kilter; as further technology is developed, scientists will be able to test out all theories surrounding déjà vu and narrow down the true cause.
