Déjà Vu According To Neuroscience

According to neuroscientists, déjà vu isn’t a memory error or a sign of an unhealthy mind. It happens as the frontal regions of the brain, which process billions of neurons, tries to correct an inaccurate memory, fact-checking the information it is receiving. This can happen once a month on average, but being stressed out, tired or fatigued may increase the chances of experiencing this feeling.

Dopamine, which is a mood-boosting neurotransmitter, plays a part in déjà vu, especially in people who experiment with dopaminergic drugs.
