Déjà experiences in epilepsy: contributions from memory research

This chapter attempts to classify the déjà states in epilepsy according to known models of memory function and the emerging research work on déjà experiences in other groups. It conducts a review of temporal lobe epilepsy — a condition in which déjà experiences are commonly reported as accompanying seizures. It describes how qualitative differences in the subjective experience associated with different déjà sensations provide support for dual process theories of memory. It considers both stimulation studies and accounts of spontaneous déjà experiences. The chapter argues that more widespread activation of hippocampal-cortical networks produces déjà vécu, distinguishable from déjà vu by the erroneous sensation of recollecting contextual information. The present neuroscientific account and classification of these memory based phenomenon will be a useful guide to future research in this area, and applicable to déjà experiences in healthy populations.
