The epileptogenic zone: general principles.
Sir Victor Horsley, a British neurosurgeon, pioneered epilepsy surgery and, in 1886, published the reports of successful cortical resections that resulted in a significant reduction in epileptic seizures in three patients (Horsley, 1886). At that time, V. Horsley assisted by J.H. Jackson (epileptologist) and D. Ferrier (neurophysiologist), identified the region to be resected by the location of...
متن کاملLocalization of Epileptogenic Zone With the Correction of Pathological Networks
Patients with focal drug-resistant epilepsy are potential candidates for surgery. Stereo-electroencephalograph (SEEG) is often considered as the "gold standard" to identify the epileptogenic zone (EZ) that accounts for the onset and propagation of epileptiform discharges. However, visual analysis of SEEG still prevails in clinical practice. In addition, epilepsy is increasingly understood to be...
متن کاملTime-Varying Networks of Inter-Ictal Discharging Reveal Epileptogenic Zone
The neuronal synchronous discharging may cause an epileptic seizure. Currently, most of the studies conducted to investigate the mechanism of epilepsy are based on EEGs or functional magnetic resonance imaging (fMRI) recorded during the ictal discharging or the resting-state, and few studies have probed into the dynamic patterns during the inter-ictal discharging that are much easier to record ...
متن کاملA fingerprint of the epileptogenic zone in human epilepsies
Defining a bio-electrical marker for the brain area responsible for initiating a seizure remains an unsolved problem. Fast gamma activity has been identified as the most specific marker for seizure onset, but conflicting results have been reported. In this study, we describe an alternative marker, based on an objective description of interictal to ictal transition, with the aim of identifying a...
متن کاملSemi-analytical homogeneous anisotropic capture zone delineation
We present an algorithm for the quick delineation of capture zones using complex discharge potential. The flow is steady and two-dimensional in a homogeneous domain with anisotropic transmissivity. The procedure accommodates an arbitrary number of injection and extraction wells at any locations throughout the flowfield, as well as regional flow, in the form of a uniform flow component. Capture ...
