ABSTRACT

A second way of scientifically explaining the déjà vu experience is that it is a byproduct of momentary biological dysfunction in the brain, which can take one of two forms. At the global level, a déjà vu may occur as a result of a spontaneous electrical discharge, or seizure. At the micro level, a déjà vu might result from a slight alteration in the normal speed of the neural message, involving either slowed or increased synaptic transmission along one specific pathway. Interestingly, some of these proposals trace back to speculation over a hundred years old that corresponds remarkably well to modern interpretations based on a more sophisticated understanding of the human nervous system.
