Update on temporal lobe‐dependent information processing, in health and disease

Abstract The past decade has been characterized by a lot of remodeling in the field of learning and memory. Both of them, often associated with neuronal oscillations, an emergent property of brain networks, are governed by temporal lobe (TL) functional connectivity. An impairment of oscillatory mechanisms indeed often leads to TL‐dependent cognitive deficits. While the classical view assigned the TL a major role in spatial information processing, new theories rather confer to the TL a more general function in cognitive processes beyond space representation. The present review covers, both in humans and in animal models, (a) the updated role of the TL in cognitive processes, addressing current debates in the field and proposing a scenario on how TL structures cooperate in order to bind an integrated representation of afferent information, (b) the oscillatory mechanisms underlying these TL‐dependent cognitive functions (theta, gamma, sharp wave ripples) and (c) how TL‐dependent cognition is altered during temporal lobe epilepsy, proposing a scenario on how reorganized TL networks in TLE leads to rhythmopathies and cognitive deficits. Temporal lobe epilepsy (TLE) is a well‐studied neurological disease. Patients do not only suffer from epileptic seizures but also from cognitive and behavioral deficits between their seizures called comorbidities. TLE animal models are therefore used to understand how and when these comorbidities arise and what their underlying mechanisms are.
