Review
The significance of deja vu is widely recognised in the context of temporal lobe epilepsy, and enquiry about deja vu is frequently made in the clinical assessment of patients with possible epilepsy. Deja vu has also been associated with several psychiatric disorders. The historical context of current understanding of deja vu is discussed. The literature reveals deja vu to be a common phenomenon consistent with normality. Several authors have suggested the existence of a "pathological" form of deja vu that differs, qualitatively or quantitatively, from "non-pathological" deja vu. The features of deja vu suggesting neurological or psychiatric pathology are discussed. Several neuroanatomical and psychological models of the deja vu experience are highlighted, implicating the perceptual, mnemonic and affective regions of the lateral temporal cortex, hippocampus and amygdala in the genesis of deja vu. A possible genetic basis for a neurochemical model of deja vu is discussed. Clinical approaches to the patient presenting with possible deja vu are proposed.

Review
Illusions of inappropriate familiarity with the current experience or hallucinatory recall of memories are reported in temporal lobe seizures. Pathophysiological hypotheses have been proposed, involving temporal limbic regions (Hughlings-Jackson), temporal neocortex ("interpretive cortex", Penfield), or both (Bancaud). Recent data acquired from presurgical investigations using intracerebral electrode recordings, demonstrate a critical role for the sub- and para-hippocampal cortices. From this, a novel hypothesis of cortico-limbic networks emerged: déjà-vu results from an abnormal synchronization between rhinal cortices and hippocampus, and reminiscences ("dreamy state") from activation of the associational function of the hippocampus in re-assembling elements of the past experience networks. "Experiential" phenomena are better scrutinized during direct cortical stimulation than during spontaneous occurrence, because it allows precise spatiotemporal correlations to be made between the illusion/hallucination and the electrical discharge features and localization. Therefore, we present a summary of the stimulation data published since Penfield's seminal studies, review the anatomical and physiological correlations of stimulation findings, and question their functional significance. We reappraise the distinct and coactive roles of the various regions involved in perception-memory processes including the hippocampus, rhinal cortices, temporal neocortex and constituent elements of the ventral stream. Additionally, we draw insights from what is known about the perception-cognition continuum underlying the construction of episodic memories. Finally, we compare the results from cortical stimulation in the epileptogenic zone with the use of stimulation for memory enhancement and explore what this reveals about the mechanisms of stimulation.

A recent laboratory study by Cleary and Claxton [2018. Déjà vu: An illusion of prediction. , (4), 635-644. http://journals.sagepub.com/doi/full/10.1177/0956797617743018] documented a relationship between déjà vu and feelings of premonition. During instances of retrieval failure, participants reported stronger feelings of prediction during déjà vu than non-déjà vu states, despite displaying no actual predictive ability in such instances. The present study further explored the link between déjà vu reports and feelings of prediction. Although feelings of prediction were more likely to occur during reports of déjà vu than non-déjà vu, they were not the sole defining feature of déjà vu, accounting for just over half of all reported déjà vu states. Instances of déjà vu that were accompanied by feelings of prediction were associated with greater feelings of familiarity than instances that were not. This was shown by a greater likelihood of reporting that the scene felt familiar and also by a higher rated intensity of the feeling of familiarity elicited by the scene when it did feel familiar. Though the present study was mainly descriptive in characterising the interrelations between déjà vu, feelings of prediction, and familiarity, the full pattern points toward the possibility that high familiarity intensity may contribute to the feeling of prediction during déjà vu.

Review
Déjà vu can be defined as conflict between a subjective evaluation of familiarity and a concurrent evaluation of novelty. Accounts of the déjà vu experience have not explicitly referred to a "conflict account of déjà vu" despite the acceptance of conflict-based definitions of déjà vu and relatively recent neuroimaging work that has implicated brain areas associated with conflict as underpinning the experience. Conflict monitoring functioning follows a similar age-related trajectory to déjà vu with a peak in young adulthood and a subsequent age-related decline. In this narrative review of the literature to date, we consider how déjà vu is defined and how this has influenced the understanding of déjà vu. We also review how déjà vu can be understood within theories of recognition memory and cognitive control. Finally, we summarise the conflict account of déjà vu and propose that this account of the experience may provide a coherent explanation as to why déjà vu experiences tend to decrease with age in the non-clinical population.
