The localizing value of epileptic auras: pitfalls in semiology and involved networks.

A more complete understanding of the epileptic aura represents an important challenge for localizing the epileptogenic zone and understanding brain networks. This review re-visits the localizing value of the epileptic aura, focusing on clinical pitfalls in epileptogenic zone detection and the importance of defining functional connectivity. We review the role of network node activation or alteration and its relationship to hub activation.
